The Stolen Rhythm: When Vietnam Lost Xuan Son and Lost Themselves

In the press conference after the match, I sat in the last row, where the lights never reach. In my notebook, I wrote down a single number: 0. Not Vietnam's goal tally in the loss to Thailand, but the number of times Vietnamese forwards received the ball inside the opponent's penalty area during the entire second half. An empty number, literally.

I have followed Vietnam national team matches for many years, from empty training sessions at youth academies to nights of blazing stands. But this was the first time I witnessed a team in red play without any contingency plan for the absence of a single player. Nguyen Xuan Son, the naturalized striker who made his mark at the previous ASEAN Cup, was absent due to injury. And Vietnam, according to expert Doan Minh Xuong on Tuoi Tre, had surrendered before the match even began.

The core problem is not the absence of a striker, but the absence of a system to replace him.

I remember the training session the day before the Philippines match, standing on the touchline watching every movement of the players. Xuan Son was training lightly then, his left leg heavily bandaged, but he was still the focal point of every ball. Teammates sought him out like an anchor, a fulcrum. When he left the field due to a recurring injury, the entire attacking structure collapsed. It was not ordinary dependence, but a form of mutual dependence: the team needed Xuan Son to hold the ball, and Xuan Son needed the team to release him. When one link breaks, the entire chain falls.

Expert Doan Minh Xuong pointed out bluntly: Vietnam is strongest when playing defensive counter-attack, but the loss to Thailand forced them to push forward chasing an equalizer. This is the self-destructive paradox: the team strongest in a game state that doesn't require possession was pushed into a situation requiring the most possession. By pulling Vietnam out of its comfort zone, Thailand had won before Sarach Yooyen's long-range shot opened the scoring in the fifteenth minute.

The match unfolded according to a script I had seen many times following Japanese teams against West Asian opponents. Vietnam dominated possession, pushing Thailand deep, but every final ball stopped at the edge of the box or was blocked at the perimeter. Nguyen Hai Long's long-range effort, the finish disallowed by VAR for Tien Linh's offside, that was all Vietnam created. A team holding the ball for seventy percent of the time yet only managing shots from outside the box is a team that has been completely decoded.

Chanathip Songkrasin, whom I had followed since his J.League days at Consadole Sapporo, played as a false nine. He dropped deep, pulled Vietnamese center-backs out of position, then circulated the ball to the flanks for runners. It was a classic Japanese football pattern: diluting the defensive block with a forward who knows how to move, not how to score. Thailand did not need a fixed center-forward. They needed a connector, and Chanathip did it excellently.

On the bench, I noticed coach Kim Sang Sik repeatedly standing up, pointing to the central area. In the second half, he switched from a back-three to a five-midfield formation, pulling Cao Quang Vinh from left-back into central midfield. It was not a deliberate tactical change, but a response to a personnel shortage in midfield. When a full-back has to play central midfield in a decisive match, it says the team lacks enough standard central midfielders. Hoang Duc had just returned from injury, lacking the fitness for a full match. It was a truth no one wanted to admit, but it was visible on the pitch.

The notable thing is that the second-half changes helped Vietnam play more cohesively. Hai Long and Hoang Duc came on, ball circulation improved, combinations became more coherent. But the goal never came. Because the problem was not rhythm, but penetration. Vietnam passed more, but no one could hold the ball long enough to stretch Thailand's defense. No one could do what Xuan Son routinely did: stand between two center-backs and turn a long ball into a chance.

In my notes, I marked the final three minutes. That is the period I usually observe most carefully, when the match is decided and players truly reveal their nature. Thailand deliberately slowed the tempo, passing among themselves in their own half. Vietnam no longer had the strength for high pressing. Players just chased the ball in vain. I counted three times Vietnamese players looked up at the stands, where fans were still singing. They were not seeking support. They were seeking an answer to a question everyone knew but no one dared to say: what will we do if Xuan Son doesn't return in time?

Expert Doan Minh Xuong spent most of the interview discussing this issue. He emphasized that Vietnamese football needs to find a replacement for Xuan Son, not just for this match but for the near future. But I wondered whether Vietnam truly has no other strikers, or whether the problem lies in a playing philosophy too tightly bound to a single striker prototype. I have watched V.League matches and seen domestic strikers like Tien Linh or Van Toan, or rising young players. But none of them share Xuan Son's physical profile. He is taller, stronger, and most importantly, comfortable facing the big center-backs of Southeast Asia.

That is why I wrote at the beginning that the problem is not the absence of a striker. A mere striker can be replaced by another striker. But Xuan Son is not just a striker. He is a system function: holding the ball under pressure, acting as a wall for midfielders, and crucially, drawing opposing center-backs to create space for teammates' runs. When he is lost, the system loses its basic operating capability. Midfielders no longer have a safe forward passing option. Defenders no longer have a target for long balls. And opposing defenses no longer have anyone to worry about.

Thailand understood this. They played a low block, ceding the ball to Vietnam in midfield, focusing solely on protecting the box. It is a tactic J.League teams often use against opponents whose attacking system depends on one individual. If you cut the supply line to that individual, the whole system dies. And Thailand did exactly that: cut the source, not the man.

But there is another aspect I think we should view more fairly. Expert Doan Minh Xuong mentioned that many Vietnamese key players were not in optimal physical condition. This is a tournament organized in a centralized format, with a dense match schedule, directly affecting player recovery. I was once asked to follow a team in an Asian competition with a match every three days, and I clearly saw that fitness is the decisive factor. When legs are no longer fresh, every tactical idea becomes meaningless. And Vietnam paid the price.

But here, we need to distinguish between cause and effect. Poor fitness may be the cause of being unable to press high in the second half. But it does not explain why Vietnam had no alternative attacking plan in the first half, when fitness was still abundant. The lack of attacking diversity is a structural problem, not a physiological one. And if we blame only fitness, we miss the opportunity to fix that structure.

In my analyses, I always try to ask about what is not being said. Here, what is not being said? It is how Vietnam prepared to deal with Xuan Son's absence. A professional team should never depend entirely on one player. Modern football requires each position to have at least two quality options. If Vietnam cannot find a backup for Xuan Son, that is a problem of selection and development, not of this match alone.

I remember a small detail I observed in a training session of a Japanese team I once followed. When a key player was absent, the coach immediately changed the drills so the whole team could adapt to a new structure. No one tried to replace that player with a clone. Instead, they changed the operating method to optimize what they had. It is the flexible thinking Vietnamese football can learn from. Instead of scrambling to find someone like Xuan Son, find a way to play without Xuan Son.

In the second half, Kim Sang Sik tried to do that by switching to a five-midfield formation. He increased central control, hoping to create more chances from group combinations. But there was no striker capable enough to finish those combinations. Balls reached the box and stopped there. It was not the midfielders' fault. They did their job correctly. It was the fault of a system not designed to operate in a worst-case scenario.

There is another detail I do not want to overlook: Dinh Bac. This young player was pushed into the role of replacing Xuan Son, and he could not do anything. Expert Doan Minh Xuong commented as much, and I do not disagree. But I want to add that Dinh Bac was not the right person for that role. He is a striker with a tendency to make runs, not a hold-up striker prototype. Putting him in Xuan Son's position is like forcing a sprinter to compete in shot put. Failure was predictable. And the criticism he received after the match is a typical football injustice: people always blame the tool instead of the one who chose the tool.

This is not the first time I have witnessed this scenario. Throughout my career following football, I have repeatedly seen Southeast Asian teams depend on a single naturalized star or one outstanding player, then collapse when that person is absent. It is a predictable pattern, reflecting a deeper problem: insufficient depth in developing players in key positions. Vietnam does not lack strikers. Vietnam lacks strikers with the physical profile suitable for international competition. And that is a foundation problem, not a single-match problem.

But I do not want to be overly pessimistic. Football is a sport of cycles. One loss does not define a team. What defines a team is how they react after defeat. Vietnam still has a chance in this tournament, and more importantly, they still have time to rebuild their attacking structure. But to do so, they must acknowledge that the problem is not merely Xuan Son's absence. The problem is that they built a system that cannot operate without him.

At the press conference, I heard a colleague ask Kim Sang Sik about plans for the next match. He answered briefly that the team would try to improve. But I wondered what improvement means here. Is it finding a way to play better with what they have, or waiting for Xuan Son to return so the old system works again? The answer to this question will determine the future of the Vietnam national team for years to come.

I left the stadium when it was already dark. On the way home, I thought about what I had witnessed. A team dominating possession but not knowing what to do with it. A coach trying to turn the tide but lacking tools. An expert pointing out problems bluntly but not offering concrete solutions. And an absent striker whose presence matters more than what he does.

In football, dependence on an individual is not a sign of strength, but a sign of fragility. Vietnam built a system around Xuan Son, and when he was no longer there, that system collapsed. It is a lesson any team should remember, not just in Southeast Asia.

When I got home, I opened my notebook again and looked at the number 0 I had written in the last row. Not the goal tally, but the number of times Vietnamese forwards received the ball inside the opponent's penalty area in the second half. It is a telling number. It says that when you lose the rhythm keeper, you do not just lose a player. You lose the rhythm of the match. And sometimes, you lose yourself.

The goalkeeper does not need glory; he only needs a goal and a heart that keeps rhythm. But when the rhythm keeper is gone, the whole orchestra plays out of time. Vietnam played out of time against Thailand. And the biggest question now is not when Xuan Son returns, but when Vietnam learns to play without him.
