Pumas and Four Gaps in the Spine: How Esteban Solari Must Rewrite His Code Before Atlético de San Luis

Pumas and Four Gaps in the Spine: How Esteban Solari Must Rewrite His Code Before Atlético de San Luis

In the 45th minute against Atlas, Álvaro Angulo went down. He had just returned from injury, had just completed his first 45 minutes in weeks, and that was all he managed to leave behind. Nobody on the Pumas bench said anything. But if you have followed this club long enough — as I have, from sleepless nights logging match footage to the moment a pandemic shut down every pitch in Europe — you know the left-back slot at Pumas has just opened a hole that the match against Atlético de San Luis cannot possibly patch with a single name.

I read the absentee list three times. Once to record it. Once to discard what I had assumed was right. Once to check for anything I had missed. Four names sit on four different lines of the team: Morales in the attack, Vite on the flank, Carrasquilla in central midfield, Angulo at left-back. One striker, one wide midfielder, one central midfielder, one full-back. If you want to paralyse a system, you do not need to break eleven positions. You only need to remove one man from each layer. That is what is happening to Pumas on Matchday 10 of the Apertura 2026.

Context: when the international calendar refuses to close

Before tactics, I have to talk about the calendar. Matchday 10 falls inside a FIFA window. Liga MX clubs still have to play while their national teams call players away. This is a structural feature of Mexican football, not an accident. The league does not pause. Clubs with more internationals lose more, and that is an inequality written into the regulations rather than a violation committed by any club.

Pumas sit in the heaviest-hit group this round. Carrasquilla of Panama, Vite of Ecuador, Angulo of Colombia, plus Morales in the attack. Four players, four nationalities, four destinations. This is what I call "geographic dispersion risk": the more nationalities a club recruits from, the more the international calendar erodes it from multiple directions at once. There is no pre-match mitigation. No compensation mechanism is cited.

Add two internal facts. First, Angulo was just back from injury and managed only 45 minutes against Atlas — meaning he had never reached the condition the coaching staff needed. Second, Calderón was already absent through injury. So at left-back, Pumas have lost both the first and second choice. This is where I want to pause longest, because it is the most dangerous part of the story, and the part a transactional transfer-news item would skim past.

Esteban Solari absorbs all of it inside a single week. He has no time to experiment. He has time only to choose.

Mapping four gaps into severity levels

I usually code every squad situation into a numbered system — what the young colleagues in Nha Trang jokingly call my "47-situation codebook". That codebook was born during six months reviewing 200 European matches from 2026 to 2026, when global football stopped. It is not an invention. It is the consequence of having nothing to watch except what had already been watched.

For Pumas, I need only four codes. Code 04: loss of a central striker inside a two-striker shape. Code 11: loss of a wide midfielder capable of stretching the pitch horizontally. Code 19: loss of a central midfielder responsible for progressing the ball from the back line to the front. Code 33: loss of a full-back on the flank the opponent most wants to attack. Four codes, four different severity levels, ranked from least to most dangerous.

Morales is Code 04. Losing a striker in a two-man frontline is a problem with a solution, because modern football supplies ready-made ways for a lone striker to remain threatening. You can push a wide player higher. You can stretch the opposing back line and attack the space behind. Every club has been through this.

Vite is Code 11. Losing a wide midfielder removes horizontal stretch, meaning the midfield must compensate by running more rather than passing more. This is the kind of loss statistics struggle to see, because it does not live in completed-pass counts but in the extra metres run to hold shape.

Carrasquilla is Code 19. Losing a central midfielder who can progress the ball is losing rhythm. But this is a special case I will return to, because the way it happened substantially reduces its real severity.

Angulo is Code 33. And Code 33 here does not stand alone. It stands alongside Calderón's injury. This is the only item on the absentee list I would call a genuine crisis.

The left flank: where the problem has no clean answer

Let us be blunt. If you are the opposing coach and you spend one evening watching Pumas footage, you will spend most of it on their left flank. Not because their left flank is bad. Because their left flank is about to have nobody in position.

Bennevendo is described as the "clearest option". I believe that, and I also believe the word "clearest" here carries a more worrying meaning than a reassuring one. Bennevendo is a utility defender, more naturally right-sided than left. When you deploy a utility player at left-back as a stopgap, you are not solving the problem — you are betting the problem will not arrive too early.

I have a way of verifying these situations, and it lives outside the stat sheet. I call it "the spare metre of GPS". GPS records distance covered, top speed, sprint count. It does not record a left-back running three extra metres toward the touchline every time the opponent switches play, simply because he has to angle his run to compensate with his weaker foot. Those three metres appear in no fitness report. But three metres, multiplied by seventy switches of play, is the entire story of a match.

GPS does not point to the winner; it points to the man who dares to run one extra metre.

The thing I fear most on Pumas' left is not a specific action. It is the moment Bennevendo realises he is out of position and therefore begins to hesitate half a second before every long ball from the opponent. That half-second is what cameras miss but strikers catch. I have reviewed hundreds of matches searching for that hesitation, and it always appears. Always.

There is a solution Solari could use: keep the ball away from that zone. Play heavily to the right, accept abandoning the left to avoid exposing the weakness. But that creates another problem: the shape becomes unbalanced, and a smart opposing back line shifts across, strangles the right, and forces Pumas to recycle to the left anyway. You cannot hide from a flank for 90 minutes. You can only postpone facing it.

Central midfield: Vite's vacuum and the Trigos question

If the left flank is an open wound, central midfield is a closed one. Vite's departure leaves a vacuum in linking the back line to the front line — what modern football calls ball progression. When you lose the man who does this, your team starts playing longer passes, and longer passes mean more turnovers in midfield.

Santiago Trigos is flagged as the "natural" replacement. I want to read that word slowly. In football language, "natural" usually means "same position, same foot, same line". It rarely means "same quality". Trigos is a structural, disciplined central midfielder who holds position. That is a different profile from Vite. Vite generates attacking rhythm. Trigos keeps the structure from collapsing.

This is a change of nature, not of position. When you swap a creator for a disciplinarian, your team does not get weaker — it gets different. It shifts from proactive to containment. For a team that needs a home win, that shift runs against the wish.

I have made this misjudgement before. In 2026, when Saudi Arabia beat Argentina 2-1, I initially dismissed it as a mental collapse by the favourite. I was wrong. On my third rewatch I counted nine occasions where Argentina fell into the offside trap, with the Saudi back line pushing up to nine metres from the halfway line. Nine metres. Not a deep block, but a line standing near the halfway line, inviting the opponent into a trap they had built.

That lesson made me warier of fast conclusions. So with Pumas, I will not say losing Vite is a disaster. I will say it is a shift of identity, and that shift can only be judged once the match is over.

The attack: Juninho alone

With Morales out, the most logical option Solari has is switching from a two-striker shape to a single striker, with Juninho highest. This is a correct decision in logic, and the most counter-punchable.

A lone striker only works when there is support from behind or from the flanks. Without it, he becomes an island. The ball reaches him, he holds it, he waits, and there is nobody to pass to. In football, that is the slow death of a centre-forward.

The bright spot is that the original report spells out Plan B: pushing a wide midfielder — Huerta or Herrera — higher. This is a variant I code as Code 23 in my system: attacking through width when you lack physical superiority in the box. You do not try to win duels in central areas. You widen the pitch, drag the opposing back line out of position, and attack the space that stretching creates.

That is a sensible choice against an opponent prone to sitting deep. It is also easily neutralised. If Atlético de San Luis accept a deep block and refuse to stretch, Pumas' passes out wide simply produce crosses into a crowded box. Crossing into a crowded box with one striker is the fastest way to lose the ball without scoring.

This is why I rate the attacking risk medium, not high. Solari has a plan and the plan is sound. But both options depend on how the opponent chooses to play. When your decision depends on someone else's decision, you no longer control the match.

The contrarian angle: the number "four" is less frightening than it looks

This is the section I want to spend the most time on, because it is the one most reports will skip.

Four absentees sounds severe. But four names are not four problems of equal weight. The codebook does not need to remember; it remembers the man who made it — and here, the codebook is telling me one of the four gaps was prepared in advance.

Carrasquilla is suspended after a red card against Atlas. That is a pre-determined sanction. Solari knew before this match that he would not have Carrasquilla. He had time to prepare for that slot — a week, perhaps two — to reorganise midfield without him. That is a very different situation from an injury occurring on the Friday before a match.

There is also a signal I read from a small detail: Víctor Arteaga had already occupied Carrasquilla's bench place before the suspension took effect. This suggests Carrasquilla was no longer first choice in his position even when available. In other words, an internal competition is unfolding in Pumas' midfield, and Carrasquilla is on the losing side of it.

If that is correct, Carrasquilla's suspension is not a loss. It is a confirmation.

This is where data and intuition usually collide. Intuition says: four men out, that is bad. Data says: one of those four was no longer a starter. I always choose data in these cases, even though my cautious nature wants to doubt both. I reviewed 200 matches just to find one moment nobody saw. Here, that moment is a name on a bench before the match kicked off.

I also want to note the difference between losing players to national teams and losing them for other reasons. When a player leaves for his country, that is an external loss. Nobody blames the coach. There is no pressure for long-term tactical change. When a player leaves through injury, questions arise about training load and fitness management. When a player leaves through suspension, questions arise about discipline. At Pumas, three of four absences are international duty and one is a ban. There is no systemic discipline problem. No systemic fitness problem. This is a loss distributed from outside, not generated from within.

What does that mean for Solari? It means the pressure on him is not about cause. It is about how he handles consequence. And that pressure lasts exactly one match.

The execution blind spot: integration is not finished

If you ask me which fact in this report is the most dangerous, I will not pick the four absentees. I will pick one sentence near the end, one most readers will skim: this team is still trying to integrate its squad and establish a rhythm of play.

That is the most important sentence in the whole source. It tells me Solari's system has not matured. Pumas are not a machine with stable operating rules. They are mid-assembly.

When a structurally mature team loses four men, it replaces four men and keeps running, because the system's rules do not depend on individuals. When an immature team loses four men, it does not merely lose four players. It loses the ability to find its rules, because the very process of finding them involved the men who just left.

This is Pumas' biggest execution blind spot. And it is a blind spot precisely because it cannot be solved inside a week. You cannot accelerate the maturation of a tactical system. You can only mask it with results. Good results temporarily hide immaturity. Bad results expose it instantly.

I have watched this many times over more than forty years. A structurally immature team always shares one trait: its results swing more wildly than its true ability. It can beat a strong side and lose to a weak one inside a week. That is not psychological instability. It is structural instability. Data is a story told in numbers, but I still hear the runner — and when the runner does not yet know where to run, every number becomes meaningless.

For Pumas, this means the match against Atlético de San Luis cannot be judged by the scoreline. It must be judged by how stable the rules remain across 90 minutes. If they win with no clear rules, that is a bad sign. If they draw while the rules begin to form, that is a good sign. I know this sounds backwards to how most fans read football. But football does not reward those who read one match correctly. It rewards those who read a season correctly.

Result pressure and the media cycle

Pumas play at home, at CU. That is a real advantage, and the source implicitly concedes it by noting the team will "play again at CU". But home advantage is often overrated in matches where the hosts must change structure. Fans do not help you hold position. The louder they cheer, the more you tend to push up — and pushing up while your left flank is compromised is a familiar recipe for counter-attacking goals.

Striking is how the source frames it: "how will Solari solve them?". That is a narrative defensive of the coach. It assumes the problem is solvable, that he has options, that he only needs to choose correctly. When media start asking "how will he solve it" rather than "will he be fine", pressure is already medium-high — but not yet at the point of questioning his job.

I do not believe in reading pressure from headlines. I believe in reading it from how journalists frame questions. An open question shows patience. A demanded answer shows impatience wearing thin. Right now, Pumas are in the open-question phase. Solari still has time. Not much.

In football, pressure is always distributed asymmetrically. The four absentees carry no pressure. They are with their national teams, or sitting out a ban. Pressure lands entirely on the replacements. Trigos, Bennevendo, Arteaga step in wearing the label "natural option". That label is a promise, and a promise always has to be paid for in results.

This is what I want young analysts to notice. When a team has stars, pressure belongs to the stars. When a team loses its stars, pressure does not vanish. It flows downward, to those beneath. It becomes more insidious, harder to see, and sometimes crueller. Over more than forty years, I have seen many young players crushed by opportunity rather than by failure. Before buying a player, I let him run three matches, and only then do I trust the offer. For Pumas, those three matches are beginning.

Talent flow: a signal about squad economics

The source contains not a single financial figure. No transfer fees, no wages, no contract lengths, no market values. I will not invent them. But there is one indirect signal worth reading.

Every solution Solari has comes from within. Arteaga, Trigos, Bennevendo, Juninho, Huerta, Herrera. Not one was bought. This is a model I call "development-first depth" — either the squad is thin, or the club deliberately cultivates youth rather than buying proven names.

For a club with UNAM's development tradition, the latter is more likely. But I only state this at low confidence, because the source provides no confirmation. A single mispronunciation taught me to rename precision. And precision here demands I say: I do not know, and I should not guess.

What I can say is this. A club relying on internal options to fill four gaps at once is a club with thin depth, whether that depth is built by budget or by philosophy. Competitively, the outcome is the same. Managerially, the cause differs. And different causes lead to different fixes. If it is budget, you must sell to buy. If it is philosophy, you must be patient. Solari does not get to choose between those two this week.

The short Apertura and the value of a single point

One thing those who do not follow Liga MX often miss: the Apertura format is very short. Around seventeen rounds, then the Liguilla. Matchday 10 is in the back half. That means time to repair dropped points is draining week by week.

In a long season, dropped points at home are a scratch. In a short one, they are a cut. And for a team that needs to return to winning ways, a home fixture against a direct Liguilla rival is a match where the value of three points cannot be measured in three points. It must be measured by the gap those three points create over the chasing pack.

This is why I call this a "six-pointer" in the broad sense. Not because it directly decides the table, but because it lands at the moment of maximum table volatility. A team can drop three places from one Matchday 10 defeat. A team can climb three from one win. For Pumas, this is a time to win, not to experiment.

But it is also a time when Solari is forced to experiment. That is football's most beautiful and most cruel paradox. You need results most exactly when you have the fewest tools.

What I will track

I do not give scoreline predictions. I never do, and I do not trust scoreline prediction as a display of expertise. Instead, I offer points to track. That is how I work, and how I advise the young to work.

First, the starting XI. I want to know whether Bennevendo starts at left-back. If he does, I want to see where he receives the ball and which spaces Atlético de San Luis attack. Pumas' left flank is where the match's story will be written.

Second, the number of strikers. I want to know whether Solari picks one or two up front. If one, I want to see whether Huerta or Herrera is pushed higher. The difference between an isolated striker and a supported one is the difference between a stalemate and a goal.

Third, passing rhythm. I want to count Pumas' unnecessary long balls in the first 20 minutes. If that number is high, Vite's vacuum has not been filled by Trigos. If it is low, Trigos is doing the structural job correctly.

Fourth, second-half stability. An immature system usually shows itself most clearly after the 60th minute, when fitness drops and instinct takes over decisions. If the rules still hold at the 75th minute, that is a genuinely positive signal.

Fifth, and most important, how the replacements react after every mistake. No stat sheet records this. A young player who errs then runs an extra metre is a player who will grow. A young player who errs then shrinks is a player who needs time. GPS does not point to the winner; it points to the man who dares to run one extra metre. In this match, the man who dares to run one extra metre will be the most important player on the pitch, even if he does not score.

A thought to leave behind

I have written about football for over forty years, and what I have learned is that matches like this teach more than any grand victory. A team in a personnel crisis does not show you how strong it is. It shows you how well it understands itself. And understanding, in football as in writing, is the one thing money cannot buy.

For Pumas, the question is not whether they beat Atlético de San Luis. The question is whether four absentees force them to rewrite their codebook in a way that, three weeks from now, when those players return, they will no longer want to revert to the old one. Sometimes a gap is the best thing that can happen to an incomplete system. It forces the system to know what it lacks.

I will rewatch this match at least three times. Once for the left flank. Once for Juninho's movement off the ball. Once for Solari's expression in the 80th minute. Three times, no more. Then I will switch off and wait for the next round, because football always answers in the following match, not the one just finished.
