"Técnico que debuta, no gana": The 10th-Minute Header and the Void Reynoso Left Behind in Liga MX

There was no rain. There was no snow. Just a ball striking the crossbar and bouncing out, and Eduardo Águila — a centre-back, a man a tactical diagram never draws into the opposition box — charging in to finish. I sat in Hai Phong, fourteen time zones from San Luis Potosí, and heard that sound more clearly than the commentator in my headphones. By that minute the score was already 2-1. But it was only when Águila put the ball in the net that the match truly ended. Atlético San Luis 3, Necaxa 1. A scoreline the Liga MX table barely registers. San Luis remain 13th on 9 points. Necaxa remain 15th on 8. Both sit a distance from the Liguilla zone that has to be measured in disappointment. But this was the debut of Juan Reynoso — Peruvian, Guard1anes 2026 champion — on the Necaxa bench. And in Mexico there is a proverb for nights like these: "Técnico que debuta, no gana." A debutant coach does not win. I have followed Mexican football since the 1990s, when I was a young reporter in Madrid. I learned one thing: a proverb is the most beautiful language for concealing that you understand nothing. But a proverb is also the language forgotten fastest. And after thirty years at the keyboard, I know I have to look back at the match, not the words. Reynoso's résumé is handsome. A Liga MX title. A coaching career across several countries. A symbolic return to Necaxa — a modest club, more accustomed to selling than buying, to living in the lower half of the table. That résumé tells supporters a story: the club has found a navigator. But a résumé never recounts the moment the ball passed a man and time stopped. It does not recount that in the 10th minute, when forward Carranza headed Necaxa ahead, the stadium fell silent as if waiting for something that had not yet happened. And what had not yet happened did happen, in the cruellest possible way for a new manager. San Luis equalised through a move I had to watch three times before I understood it fully. A composed build-up down the left. The ball switched to the opposite side. David Rodríguez delivered a second cross. Felipe Mora flew through the air to head it. It is a classic attacking pattern analysts call a far-post overload — loading one flank with ball and bodies, then bending the delivery around the defensive block to find a runner arriving at the back post. Every run is an unfinished poem, waiting for someone else to complete it. Morales leapt, and the poem closed with a head. To be clear: this was no accidental goal. It was the product of clear intent. San Luis, 13th and fresh from a poor run, did not try to force the ball through the middle. They chose the left flank as their main corridor of progression, dragged the Necaxa block to one side, and punished the space on the other. That is calculated football, even if the scoreline had not yet said so. But San Luis's other two goals are a different story entirely. And this is the genuinely important part of this match. The second goal came from a scramble in the box. Rafael Llorente fired in a shot, the ball deflected, and Necaxa goalkeeper Andrade turned it into his own net. A situation professionals call the second ball — the loose ball after the first contact, where the match is decided by whoever reacts faster in that chaotic pocket of space. Some goals are not in the tactics; they are in the air. That ball did not follow a diagram. It followed the instinct of whoever charged in first. And Necaxa lost that race of instinct. The third goal tells an even clearer story. A shot against the crossbar. The ball rebounds. And Eduardo Águila — a centre-back — is first to everything to finish it. A centre-back scoring in a decisive minute is no longer unusual in modern football; it is a consequence of teams pushing centre-backs forward into set pieces and second phases. But Necaxa leaving an opposing centre-back free in their own box at the pivotal moment is a matter of defensive organisation, not luck. The sound of the ball hitting the ground is the last sound of the truth. And the truth in San Luis Potosí that night was this: two of Necaxa's three concessions came from exactly one zone — the second-ball area in their own box. One from the own goal after a deflected shot. One from the rebound off the crossbar. Both were consequences of nobody clearing the second ball before the opposition did. This is the kind of error a coach analyses on video, not with emotion. And it is the kind of error a new manager typically inherits from his predecessor rather than creating in a single training session. But the real story of this match is not Necaxa losing. It is San Luis winning — and the possibility that the win is deceiving all of us. Wait. Look at the scoreline another way. San Luis, 13th, fresh from a bad run, needed an own goal from the opposing goalkeeper to move ahead of a side sitting 15th. Two of their three goals came from scrambles, not designed moves. Remove that own goal from the equation and the match could have finished 1-1, and nobody in San Luis Potosí would be talking about a successful evening. This is not criticism. It is a reading of the result with the caution the scoreline does not provide. Three points are still three points. But a team wanting to escape the lower half cannot rely on opponents putting the ball into their own net every week. And their next match — away at Pumas, a traditional Liga MX heavyweight — will be a far more honest test than last night. And Necaxa? They host América next. This is the fixture every lower-half Liga MX side must endure with eyes shut. América have just entered their Clásico Nacional test against Chivas, and no deep analysis is needed to see that a side 15th on 8 points, having just lost its new manager's debut, faces one of the hardest games of the season. This is where I must confront that proverb. "Técnico que debuta, no gana." It is good. It is compact. It is memorable. And it is doing the job proverbs do best: making people believe a random result is a rule. One match is not enough to judge a coaching project. It is not enough to prove a proverb either. Reynoso has had exactly 90 minutes under the Necaxa lights, and in those 90 minutes his team took the lead in the 10th minute with a textbook header. Had the match ended at minute 15, today's story would be about a champion returning at the right moment. More striking is how Mexican media framed the fixture before the ball rolled. The proverb appeared in the headline, turning an ordinary sporting event into a fairy tale that had not yet happened. But a coach cannot be judged by what did not happen to his predecessor's team. Reynoso's résumé was handsome before this match. Reynoso's résumé is handsome after it. The problem is that the résumé is not the answer to Necaxa's problem. Necaxa need a defence that clears second balls. Necaxa need a goalkeeper who stands in the right place after a deflection. Necaxa need a defensive system that does not leave an opposition centre-back free in the box in a decisive minute. These are three very specific tactical requirements, and Reynoso can solve them. But he cannot solve them in one evening. I wonder whether anyone at Necaxa is looking at the same thing I am. Three goals conceded in two scrambles. One from an own goal. One from a rebound off the crossbar. If the club's analysts are seeing this, it is a very specific week of work: video, forwards, clearing combinations, defensive organisation. If they are not, the América fixture will be another night like this — a beautiful image in the first 15 minutes, and an ending nobody wants to remember. But let me be honest about the limits of what I know. I do not have this match's expected goals. I have no pressing metrics, no possession figures, no official lineups. I have four goals, described in a short report, and thirty years of experience reading matches from very little data like this. Those thirty years taught me two things. First, matches decided by second balls usually speak about defensive preparation more than attacking quality. Second, wins that require an opponent's own goal are usually rated more highly than their true value. So I am not saying San Luis just played a great match. I am not saying Reynoso just failed. I am saying San Luis just hit the jackpot, and Necaxa just exposed a fixable weakness. And I am saying Mexican football, like every other football, prefers stories about heroes and failures over stories about the second ball in the box. That is why I was still at the screen near dawn, rewatching the slow-motion of the 10th-minute header. Before it, Necaxa led. Cabrera beat his man, the ball was played in, Carranza headed home. A move so fine it made you forget it came just 10 minutes after the whistle. In that moment, Reynoso's project had just been born, and it breathed. It had shape. It had direction. By the 90th minute and beyond, that project was still breathing, but on a different rhythm. Not the rhythm of a navigator, but the rhythm of a man clinging to what was left of an evening. I do not know what will happen to Juan Reynoso. Nobody does. But I know that after last night, every Necaxa match will be viewed through the lens of a proverb. If Necaxa beat América, the proverb will be forgotten. If Necaxa keep losing, the proverb will become a verdict. And between those two possibilities sits a 55-year-old coach trying to do what modern football makes hardest: build something slow enough to stand, in an environment demanding instant results. There is a question I want to put to everyone who has read this far. When we call a match a "success" or a "failure", what are we calling it? Three points on the table? Or a style of defending that can carry those three points across a whole season? San Luis have three points but no answer yet. Necaxa have no points but now have one very specific question to answer this week. And all of us — sitting fourteen hours from the stadium, rewatching slow-motion clips near dawn — should perhaps ask ourselves with whose eyes we are watching it. We do not watch football with our eyes; we watch it with our memory. But sometimes memory needs to be filled with one specific number: the 10th minute, one header, one ball passing a man, and time stopping. No rain fell in San Luis Potosí. But Reynoso's history at Necaxa has just begun to get wet.
