Petkovic, his staff and his players
under OlympIA's scalpel

In Algeria, everyone is debating the record. OlympIA's AI actually crunched it.
Vladimir Petkovic reunites with his former Switzerland players before kick-off
Before kick-off of Switzerland–Algeria: Vladimir Petkovic reunites with the players he coached for seven years at the head of the Nati (2014–2021). Contrary to what went viral on social media, this photo was not taken after the defeat: it was taken before the match.

Figure 1 The starting line-ups. In yellow, the two match keys flagged by OlympIA: Manzambi (★) — three goals and two assists coming into this game, stationed opposite the flank of Mandi (⚠), 34, who has been losing sharpness and aggression for a few seasons — and Maza, the tournament's best dribbler, shifted to a No. 9 role he had never occupied.

The story of the match

Algeria start strongly: possession, a high press, and as early as the 6th minute the best Algerian chance of the night — Maza slides Belghali in, a cut-back cross, Mahrez cleverly lets it run for Aouar, whose strike from the penalty spot grazes the post. Then everything tips on Switzerland's first real transition: in the 10th minute Vargas releases Manzambi into the space behind Belghali; the young Fribourg man beats Mandi in the sprint and squares for Embolo at the far post. One goal, one move, ten minutes.

Switzerland then control without straining. Algeria regain a semblance of threat before the break — a scuffed Chaibi shot gathered by Kobel (43rd), an off-target attempt from a well-placed Maza (45th+2) — but the return from the dressing room is fatal. The 2-0 sequence deserves a freeze-frame, because it condenses the whole match: in the space of a few seconds, three Algerian balls are handed straight back to Swiss feet — a loss from Maza, a botched clearance from Bensebaini, then Belghali's clearance straight up the middle off Zakaria's driven cross. Three consecutive gifts, zero counter-pressing to repair them, and Ndoye collecting at the edge of the box with all the time to control and to place it beyond Zidane's reach (46th). This is not an individual error: it is a chain of technical insecurity within a structure that forgives no imprecision, for lack of a safety net behind the ball.

In the 50th, Mahrez's volley from a Belghali cross is cleared off its line by Zakaria — the Fennecs' only real riposte. The closing stretch is Swiss: substitute Rieder is blocked at the last instant by Belghali (75th), then misses the unmissable in front of an open goal, his effort repelled by a decisive Zidane save (81st). The 2-0 almost flatters Algeria. A few minutes after the final whistle, Riyad Mahrez announced his international retirement.

A line-up built on five gambles

Petkovic lined up a 4-3-3: Zidane; Belghali, Mandi, Bensebaini, Aït-Nouri; Bentaleb, Zerrouki, Chaibi; Mahrez, Aouar, Maza. Five players held a different role from the previous match — a game that had ended with three goals against Austria. The heaviest gamble: Ibrahim Maza, the dazzling No. 10 of the group stage and the tournament's best dribbler, planted in a No. 9 role he had never held in his career, a light profile sent out alone against the Akanji-Elvedi pairing. A false 9 only works if runners dive into the space he vacates by dropping; yet Mahrez and Aouar also drifted inside, into feet. So Maza drew in the Swiss centre-backs... for no one. Second gamble: Aouar, a creative midfielder, converted to left winger to cover Amoura's injury. Third: Chaibi dropped one line deeper. Fourth: Boudaoui, a regular starter, sent to the bench. Fifth: Zidane restored in goal after being sidelined mid-tournament. Five simultaneous gambles for a knockout match, against an opponent fielding its full reference eleven.

The block cut in two: highways and dead ends

The structural flaw comes down to one measurement: in the attacking phase, nearly fifty-five metres separated the Algerian attacking line from the Mandi-Bensebaini pairing, which stayed level with the centre circle, with Bentaleb alone to cover the vast central desert of second balls.

Figure 2 Algeria's settled attacking phase (attacking towards the left). The Swiss arrow-block shuts down the cut-backs, the flanks end in dead ends — and Manzambi is already turned towards the highway at the very moment Algeria attacks. Switzerland defend and prepare their counter from the same position.

In attack, this set-up produced dead ends. The plan was legible: Mahrez and Aouar move inside to free the flanks for wing-backs Belghali and Aït-Nouri, whose overlaps are meant to end in cut-back crosses. But a cut-back plan with no centre-forward is a car with no engine: no target in the box, and the Xhaka-Freuler double pivot locked down precisely the cut-back zone. The Swiss block, compact over twenty-five metres, systematically sent the Algerian build-up backwards — that sterile horseshoe possession that gives the illusion of control without ever threatening the keeper. The full-backs, for their part, were caught in a fatal in-between: too high to re-form a block on losing the ball, too low to offer a real option.

Conversely, Switzerland built out cleanly: Akanji, Elvedi and the double pivot formed a short passing diamond in permanent superiority against an Algerian press reduced to two or three players. And in defence, the Algerian set-up opened highways: one or two vertical passes were enough to eliminate six players at once. Manzambi, permanently posted in the right half-space, attacked the space behind Belghali — drawing Mandi, thirty-four, into lateral runs that are no longer his register, a defender who retreats without committing. Note the fairness of the diagnosis: Belghali, at fault on the clearance for the 2-0, otherwise finished his match rather well (the decisive block on Rieder in the 75th, the cross for Mahrez in the 50th). The weak link was not a man, it was the architecture.

OlympIA's eye

The app breaks down every goal conceded into a causal chain: the pressing trigger, the line breached, the distance from the first defender to the shooter, the shot's preparation time. On Algeria's goals conceded this tournament, the shooter almost systematically had comfortable preparation time — the statistical signature of a structural defect, not a run of bad luck.

A press with no grammar — and the tournament's bill

Algeria's high press was a matter of individual initiative, never of system. An effective press requires collective triggers (a backwards pass, a poor touch, a ball steered towards the touchline), coordinated runs that close passing lanes, and immediate counter-pressing on the loss. Algeria had none of this: each man pressed as he pleased, always leaving an escape lane open. The cruel paradox of a disorganised press is that it worsens the very ill it claims to cure: the more the forwards push up without coordination, the wider the highway behind them grows.

The bill runs across the whole tournament: nine goals conceded in four matches — three against Argentina, one against Jordan, three against Austria, two against Switzerland — a striking share of them on shots prepared with no opposition. Messi's hat-trick in the opener (3-0) is the canonical illustration: a De Paul pass slicing through two lines before a curling strike from twenty metres, a second goal from a ball parried by Zidane after a long-range Mac Allister effort, and a third where the Argentine captain literally had time to control at the edge of the box before adjusting. Jordan's first-ever World Cup goal and Austria's counters in the 3-3 tell the same story: shooters alone, several metres from the first defender, who receive, control, advance, set, shoot — without fearing a recovery run that will never come, nor the commitment of centre-backs who defend while retreating. An analyst's precision: that retreat without commitment is the rational behaviour of abandoned defenders. With no screen in front of them and no recovery behind the ball, going in on the carrier means getting beaten. The symptom is individual; the disease is structural.

MESSI'S HAT-TRICK (ARGENTINA 3-0): THE SAME DIAGNOSIS THREE TIMES ① 17th — the pass that slices through midfield line defensive line DEP 2 lines eliminated MES 20-metre strike into the top corner — no one steps out on the carrier. ② 60th — the unguarded rebound MAC long-range shot ZID parried into the middle MES A box fox alone on the rebound: no marking in the zone of truth. ③ 76th — the time to control GON MES a bubble of time and space DEF backs off, hands behind his back Control, set-up, curled with the left at the edge of the box. 3-0.
Figure 5 Messi's hat-trick broken down: a vertical pass that eliminates two lines, an unguarded rebound, a bubble of time at the edge of the box. Three goals, one single flaw: no one between the ball and the goal to engage the duel.

The gifted balls: an inventory of the offerings

There is a common thread running through this whole campaign that deserves its own heading: balls handed straight to the opposition. Not losses under a heroic press — offerings, in the zones where they kill. OlympIA distinguishes four families, all present in Algeria's matches: the botched clearance under pressure (the defender who plays forward with no short option, for lack of a connected block); the aerial claim or free kick mishandled by the keeper; the clearance straight up the middle (the panic hoof, which lands at the edge of the box where no one covers); and the save parried into the zone of truth, with no defender for the second ball. The table below lists the most costly documented offerings.

Switzerland (0-2)46thTriple offering: Maza loss, Bensebaini botched clearance, Belghali clearance up the middleNdoye, all the time to control: 2-0

Three observations. First, the recurrence of the same signatures: Bensebaini in build-up (Nigeria 23rd, Switzerland 46th), Zidane on interventions parried towards danger (Nigeria 29th, Argentina 60th). Next, the root cause: a player does not "give" a ball away by chance. He gives it because he has no short option — the block cut in two deprives the carrier of support inside fifteen metres — because he plays under fear — the unstable dressing-room statuses — and because he knows no counter-pressing will come to repair his loss, which pushes him towards the panic clearance rather than the constructed build-up. Finally, the fatal asymmetry: every Algerian offering became a clear chance for the opponent, while the opponents' losses cost nothing — the Fennecs' disorganised press never turned a recovery into a shot. Against Nigeria, the symbol is cruel: four major offerings on one side, zero Algerian shots on target on the other.

OlympIA's eye

For each team OlympIA tracks the "passes to the opponent" metric: balls delivered straight to the opposition in one's own third, weighted by the danger of the situation created. Crossed with the average distance between lines, it explains why the same players look serene at club level and jittery on international duty: it is not the foot that trembles, it is the structure that isolates.

The first ten minutes: the false signal

Algeria monopolised the ball early on. A deliberate trap? Yes — but not in the conspiratorial sense. The Swiss plan was public in its logic: against a team that needs the ball but suffers without it, you concede a possession that does no harm, you defend in a compact block, and you strike on the first transition. Swiss observers confirmed it afterwards: this feeling-out round was expected, the Fennecs being known for wanting to keep the ball precisely because they dread being deprived of it. Algeria's dominance in the first ten minutes was therefore not a conquest, it was a concession. And does it take a leak, a plan "whispered" to the opponent, to explain such a perfect reading? No. Algeria's flaws had been plainly visible since the 3-3 against Austria, every modern analysis unit has the group-stage data — and the irony of the tie was that the true insider was Petkovic himself, seven years at the head of the Nati. Switzerland did not guess: they read what Algeria had been spelling out for three matches. And, as we shall see, for far longer than three matches.

Part Two — Evaluating the coaching: Petkovic and his staff

The analysis of a knockout match does not stop at the pitch. OlympIA evaluates a staff across seven domains: the lesson of precedents, squad construction, the playing model, match preparation, man-management, in-game coaching, and the capacity for self-correction. Over this cycle, the verdict is harsh on all seven.

01The Nigerian precedent: the error foretold, punished, then replayed

Everything was written five months before Vancouver. Quarter-final of AFCON 2025, Marrakech: Petkovic prefers Amoura to Baghdad Bounedjah up front. Nigeria impose their rhythm from kick-off, pin the Greens back in their own half, and Algeria can count themselves lucky to reach the break without chasing the game. They crack after the interval, lose 0-2, and never recover — no reaction, no revolt, the three late attacking changes in the 59th (Hadj Moussa, Boulbina, Bounedjah) never seriously troubling the Nigerian keeper. The Vancouver script, all but identical in score, was already written: opponent dominance from start to finish, no focal point, substitutions with no effect, no grit to come back.

The most damning came from the opposite bench. Nigeria coach Eric Chelle publicly described his relief on seeing the line-up without Bounedjah, explaining that his defence then had no threat to watch; he also flagged the non-use of Abdelli and how late the Algerian substitutions came. When the opponent explains your own flaw in a press conference, the professional minimum is to take note. Petkovic did the opposite: Bounedjah was dropped from the March camp — a sidelining perceived as brutal even in the dressing room, for a man who had played four of the five AFCON matches — then from the World Cup squad. And for an even more prestigious occasion, the staff tried the false-9 experiment again, this time with Maza, an absolute newcomer to the role. Same gamble, same physically superior opponent through the middle, same 0-2, same absence of reaction. An error made once is a lost gamble; the same error replayed after being publicly explained by an opponent is a professional failing. The Marrakech warning ignored

The two Nigerian goals deserve their illustrative diagrams, because they already show everything that would recur at Vancouver: the marking absent in the box, and the wide channels opened behind an exposed defence. A chilling detail: Nigeria's 1-0 falls in the 46th minute, in the first minute of the second half — exactly like Switzerland's 2-0 five months later. Twice, Algeria are caught on the return from the dressing room, the precise moment a well-coached team tightens its vigilance.

Osimhen places his header unopposed. 1-0, 46th.
Figure 6 Nigeria 1-0 (46th): Onyemaechi cross from the left, Osimhen abandoned at the far post. Marking in the box is a reflex of automatism — precisely what a team reshuffled every match does not have.

Figure 7 Nigeria 2-0 (57th): the big central channel behind an exposed defence — the same highway Manzambi would exploit five months later in Vancouver. Note: that day, Algeria finished the match without a single shot on target.

02Squad construction — the original sin

The squad unveiled on 31 May counted four goalkeepers (Zidane, Benbot, Mastil, plus Ramdane, a reservist accompanying the group) for a position where only one plays — while the attacking sector contained no penetrating left winger. Mahrez and Hadj Moussa are right-footers of the right flank, Gouiri and Amoura are central, Benbouali is a target man: the Brahimi-Belaïli profile, that unbalancing dribbler who has historically structured the Fennecs' attacking play, did not exist in the group. Left out: Bounedjah, the only true box No. 9 able to give a target for the wing-backs' cut-backs — and whose absence also stripped the group of experience, mileage and grit, precisely what was missing at 0-2; Kebbal and Abdelli, creative left-footers; Bennacer, who publicly voiced his bafflement. Asked about these choices, Petkovic declined to justify them in detail. Direct consequence: the day Amoura got injured, there was no like-for-like cover — hence Aouar as winger and Maza as No. 9. And the day they had to chase the game, the bench held neither a focal point nor a game-breaker. The choices of May closed off the options of July. Major failure

03The playing model — nowhere to be found

A national coach has little training time; his only wealth is repetition. Petkovic did the opposite: five different line-ups in five AFCON 2025 matches, three different elevens in three World Cup group games, a fourth reshuffle for the Round of 32. And the nuance makes it worse: the great coaches who rotate change names, never the structure — the position is defined before the man. Petkovic changed the roles themselves: Aouar as winger then withdrawn, Maza as 10 then 9, Chaibi as a shuttler then dropped deeper, Boudaoui a starter then banished, the keeper in permanent competition. No automatism can be born in these conditions — not the instinctive one-two, nor the anticipated shift, nor the reflex cover. That is precisely what was missing in the dead ends and on the highways. No identifiable project

04Match preparation — five gambles against a settled eleven

To field five players in new roles for a knockout match, including his best performer of the tournament in an unprecedented position, against an opponent whose number-one strength — stability — Petkovic knew better than anyone: the preparation of this match stacks up the contraindications. Add to that the absence of any anticipated answer to obvious threats: Manzambi was coming off two and a half matches with three goals and two assists, his lane of action was identified by every observer, and no doubling arrangement was planned on his flank. The popular call for a back three to protect Mandi was debatable mid-tournament; but the minimal fix — a real screen and a block tightened to fifteen metres — required no revolution and was never applied. Preparation against type

05Man-management — trust squandered

Three cases sum up the problem. The keeper: Luca Zidane a starter, sidelined mid-tournament after middling displays, then restored for the knockout match after public hesitation — the worst possible treatment for a position whose value rests entirely on trust and on automatisms with the defensive pairing; that he ended up saving the 3-0 in the 81st does not absolve the method. Maza: rewarded for his status as the competition's best dribbler with a move to a role he had never held. Boudaoui: starter, banished, recalled in the 71st of a lost match. Add Bounedjah, dropped in a manner felt as brutal even in the dressing room, Bennacer with no convincing explanation, and Mahrez — for whom this was the final tournament, his international retirement announced in the wake of the whistle — left without a single combination partner for his farewell. A dressing room reads these signals: when statuses change every week, psychological safety disappears, and with it risk-taking and grit. The three consecutive losses on the 2-0 — Maza, Bensebaini, Belghali, three balls handed back to Swiss feet — are that too: the technical signature of players playing with fear in their gut. Erratic management

06In-game coaching — swaps, not a plan

Trailing 2-0, Algeria needed a restructuring; they got swaps. In the 59th, Gouiri and Hadjam for Aouar and Zerrouki; in the 71st, Hadj Moussa and Boudaoui for Bentaleb and Mahrez. Four like-for-like changes, no modification of the block, no target added in the box to finally give the cut-back crosses a meaning. Gouiri came on into the same desert as Maza; Hadj Moussa, a one-on-one dribbler, found himself with no combination partner within twenty-five metres — his failed cameo is that of a structure, not a player; Hadjam, a natural left-back, was shuffled around the set-up while attacking options stayed on the bench. To take off a holding midfielder at 0-2 without reorganising the cover, then to remove the captain and the most experienced midfielder in one go: the sequence sketches no legible intention. A telling detail: against Nigeria already, Chelle had publicly judged Petkovic's changes late, coming around the hour mark. Five months later, first change in the 59th. Nothing had moved. Opposite him, Yakin changed nothing at half-time — and his first double change nearly produced the 3-0. Reactive, with no guiding idea

07The analysis staff — the blind spot

This is perhaps the most damning point, because it concerns not a choice but a function. The same structural defect — spread lines, central highways, unopposed shooters — produced goals against Argentina, against Jordan, against Austria, then against Switzerland. And the same attacking gamble — no specialist No. 9 in a knockout match — had already cost a continental quarter-final, with the instruction manual graciously provided by the opposing coach. Five top-level matches, five times the same causal chain, zero visible correction. A video-analysis staff worthy of the name identifies this pattern after the first match; it corrects it, at worst, after the second. Meanwhile, the opposing staff were reading Algeria like an open book with public data. When your opponent knows you better than your own bench, the problem is no longer tactical: it is organisational. A failing or unheard function

Proof through the line-ups: the complete history since AFCON

From the first match of AFCON 2025 to the World Cup Round of 32, here is Algeria's entire official run under Petkovic: ten matches, the systems used, and the line-ups where they are documented. Never the same starting eleven twice. And note the statistical trap: the rotation "worked" as long as the opponent was weak — four straight AFCON wins over Sudan, Burkina Faso, Equatorial Guinea and DR Congo masked the problem. As soon as the level rose, Nigeria then Switzerland, the bill came in: two knockout matches, two 0-2s, zero goals scored.

* Eleven reconstructed from the changes documented by the press for the following match (Zerrouki in for Bentaleb, Mahrez for Hadj Moussa, nine players retained). “n/a”: line-up not disclosed in our sources — the specialist press documents five different line-ups in five AFCON matches.

The raw record: ten official matches, ten different starting elevens, and a nominal system that is almost constant — 4-3-3 (or 4-2-3-1 against Nigeria and, depending on the reading, against Switzerland) — which masks total instability of men and roles inside the shape. This is the most subtle and the gravest point: the number on the blackboard barely changed, but everything changed within it. Follow the individual trajectories and the chaos leaps out. Maza: a No. 10 playmaker against Nigeria, Argentina and Jordan — then an unprecedented No. 9 against Switzerland. Boudaoui: a starter in the AFCON quarter-final and the first two World Cup matches — banished against Austria and Switzerland, recalled in the 71st of a lost match. Gouiri: a starting centre-forward and decisive scorer — sent to the bench for the knockout match in favour of an improvised false 9. Aouar: substitute, substitute, starter-provider on the left, then withdrawn on the hour of the next match. Aït-Nouri: starter, starter, starter, bench, starter. The keeper: in open competition mid-tournament. Across the documented matches alone, sixteen different outfield players were fielded from the start, and not a single midfield trio was kept together for two matches running. That, in numbers, is the exact definition of the absence of automatisms.

A note on method: match-by-match individual ratings are not reproduced here, because no homogeneous, verifiable scale covering the whole campaign exists in public sources — we prefer established facts (scorers, providers, starts) to reconstructed ratings. Opposite them, in Vancouver, Switzerland fielded a stabilised reference eleven — and needed nothing more.

Conclusion — What to take away

The diagnosis comes down to a causal chain, each link flowing from the previous one: a continental warning ignored in Marrakech; an unbalanced squad missing key profiles; chronic instability that forbade any automatism; a possession structure cut in two, with no screen and no protection of second balls; an individual press that widened the highways instead of closing them; coaching limited to late swaps; and a staff unable to correct a flaw that recurred from January to July. Switzerland, stable and patient, only had to press.

But the heaviest finding goes beyond this match: it has recurred since the very first AFCON game. Choices that appear random, with no legible logic from one match to the next. Internal competition killed in the egg, because too many starts came down to default rather than merit — out of a squad of twenty-six, barely fourteen players truly counted in the rotation, the rest of the group serving as scenery. No automatism could ever be born: the line-ups changed, and worse, the players themselves changed role from one match to the next — Maza from 10 to 9, Aouar from midfield to wing, Chaibi from one line to another. The mechanical result: every player found himself, in every match, next to different positional neighbours. Yet international football is precisely the art of playing the same men together long enough that they no longer need to look for each other. A bitter epilogue: Riyad Mahrez announced his international retirement in the wake of the whistle, and by the next day the press was reporting that the federation was seeking to part with a coach whose contract had been extended to 2028 just before the tournament.

What a data-driven audit would have found

Let us coldly restate the facts already established in this report: an identical precedent publicly explained by the opponent five months earlier and ignored; players dropped from the squad without their profile being replaced; a keeper kept in uncertainty mid-tournament; five roles changed at once for a knockout match; a decisive player and scorer in the two previous games sent to the bench with no legible tactical justification. None of these choices, taken in isolation, is necessarily a mistake. But their accumulation, documented in black and white match after match, draws a pattern that no rigorous selection process would have let pass without correcting it. Had a tool like OlympIA — continuously evaluating, with transparency and on the sole basis of data, player performance and the coherence of the staff's choices — accompanied this campaign, several of these decisions would probably never have been validated: part of the called-up group would likely not have made the list, and part of the starters fielded in Vancouver would probably not have earned that status. This is not one tactical opinion among others: it is what the facts, once laid end to end, indicate with rare consistency.

The perspective

A World Cup is not won on individual quality alone. It is won with heart and grit — look at what far less gifted nations, a Cape Verde that shook this tournament to the point of challenging Argentina, an Egypt carried by an entire people, managed to produce with ten times less raw talent than this Algerian generation.

The next coach will therefore have a mission that goes beyond the tactics board: to pass on values. Heart, love of a flag, a sense of national responsibility — those things are not decreed in a pre-match team talk, they are embodied. He will also have to work on the base: to lean on training academies, like Paradou AC, whose youngsters grow up and play together from the earliest age — this is exactly the model that made the strength of the France team, whose backbone comes out of academies where automatisms are built over ten years, not ten days.

“That was my last match, lads. I’m disappointed to finish on a defeat, on an exit where I think maybe we could have done better.”

“Let’s be honest with ourselves, lads — this is the very top level. At this level, when you make a few mistakes, you pay for them instantly.”

“Thank you for everything, lads. It’s been a great adventure all the same. We mustn’t sell short what we’ve done. I was proud to have spent these twelve years here, with other generations, and with you now.”

“You have quality — keep going, don’t give up. The most important thing, when you come here, is to play for the country, for the flag. Keep that in mind. Every minute, every match you play with the national team, it’s for the country.”

“As for me, I did what I had to do. There were good things and less good ones. I leave with my head held high. I’m happy and proud of everything we did. I’m proud of you. I wish you the best with the national team, but also at your clubs and in your careers.”

Riyad Mahrez, captain of the Fennecs, to his teammates after his final match in the national shirt

These words, spoken in the minute that followed the elimination, say what twelve years of international football should have passed on to an entire dressing room: playing for Algeria is not one more line on a CV, it is a commitment that must inhabit every touch, every recovery run, every second of play. It is precisely that grit, and not some extra talent, that was missing on the Vancouver pitch — and it is what the next staff will have to relearn how to circulate through the group, from the youngest prospect to the most capped starter. As for the captain, football history is full of international retirements later revisited: ours waits, with respect and hope, for Riyad Mahrez to reopen that door one day.

Beyond the analysis — a word from the team

It’s too soon, captain — Algeria still needs you

Here, it is no longer OlympIA speaking. Its models, its scrapers and its data delivered their verdict — cold and documented — in the pages above. This message comes from somewhere else: from the women and men of Brains ’n Gains, football lovers before they are analysts. As human beings, and not in the name of the machine, we want to tell you one simple thing.

At thirty-five, Riyad Mahrez has chosen to close the international chapter after twelve years and one last match. We fully respect that choice — but we find it premature. Our national Messi remains, even today, the most destabilising player in this squad: the very man whose header in the 50th minute, cleared off the line, was Algeria’s only true riposte of the night. Modern football has never rewarded the longevity of the greats as it does now: Lionel Messi carries Argentina at thirty-nine, Cristiano Ronaldo is still scoring at forty-one, and Cape Verde’s veteran keeper, at nearly forty, has just given an entire people the tournament of their lives. The door should not, in our view, close so soon. An Algeria in full rebuild would need his experience, his composure and his grit to guide the rising generation — at least for one more cycle. Come back, captain.

Coming next — Report 2/2

This report laid out the diagnosis: the match, the mechanisms, and the full audit of the outgoing staff. One question remains, called for directly by the facts gathered here — who should take over, and by what criteria? Brains 'n Gains will soon publish the second part of this analysis: "Who to succeed Petkovic? The OlympIA grid for the next coach" — ten non-negotiable criteria, a scale marked out of 100, the factual profiles of every name cited in the public debate (Belmadi, Bougherra, Yahia, Halilhodžić, Desabre, Queiroz, Renard, Madoui, Abdou, Amrani), and three collegial-staff scenarios for what comes next.
