The Rhythm of a Team Getting Back on Its Feet: Notes from Vietnam's Training Ground After the My Dinh Fall

Minute 79, stand B of My Dinh Stadium, a man in a blue jacket stood up. He did not shout, did not clap, did not turn to the person beside him. He walked toward gate six, slowly, as though leaving a meeting rather than a match. I wrote in my notebook: 17:42, stand B begins to empty. On the evening of March 26, 2026, Vietnam lost 0-3 to Indonesia at home. It was the heaviest defeat to Indonesia in the memory of most supporters in the ground that night, and it was the match that closed a cycle. Less than an hour after the final whistle, the Vietnam Football Federation announced it had terminated the contract of head coach Philippe Troussier. The statement was short. It mentioned nothing about tactics. I stood in the mixed zone as the players walked through. Nobody cried. That is what I recorded, and it is what I still have not fully understood more than two years later: after the heaviest defeat in years, the Vietnamese dressing-room area was silent like a classroom copying notes. One player bent down to retie his laces, though his laces were still tied. Another stood staring at the scoreboard far longer than it takes to read three numbers. A physio folded a cold towel, unfolded it, folded it again. The stadium had no audience left, but I could still hear the pulse of the match. That night I did not file. I sat in a hotel on Kim Ma Street and copied out three pages of notes, crossed out two lines, then left the crossings in. That is how I have worked since 2026, when I was writing for local radio stations: wait until there is enough evidence, then speak. Some things never appear on the scoreboard, yet they decide everything. On May 3, 2026, the Vietnam Football Federation announced its new head coach: Kim Sang-sik, born in 2026, South Korean, who had led Jeonbuk Hyundai Motors to the K League 1 title in 2026. I read that announcement from my apartment in Haeundae District, Busan, where I have lived and worked for years as a training-ground observer, filing football stories for the Korean market. In my profession there is one thing I learned very early: a coach's reputation does not describe the rhythm of the team he leads. Kim Sang-sik's CV is beautiful in the way of a man who has won in the K League. But Korean football and Vietnamese football run on two different rhythms. One operates through intensity and block discipline; the other operates through relationships and collective emotion. Whoever can fuse those two rhythms survives. Whoever brings only one of them across dies quickly, and that death is never recorded on the electronic board. I had seen it once before. In 2026, at the age of 31, I left a job as a sports web editor to become an official training-ground observer for Busan IPark in K League 2. That season the team played 36 matches, scored 52 goals, finished third and missed promotion by exactly 4 points. I followed every tactical session of coach Kim Do-hoon, especially the 4-2-3-1 he introduced from March, and for seven straight months I watched Lee Dong-jun, number 11, improve week by week. Those numbers, 52 goals and 4 points, appear in every report. What appears in no report was the instability in the dressing room between two foreign players, which I discovered quietly but never dared to say out loud, writing it only in my personal diary. Seven years later, rereading that diary page, I understand why the Busan IPark of 2026 scored 52 goals and still did not go up. Goals are a matter of the feet. Promotion is a matter of the shoulders. In May 2026 I flew from Busan to Hanoi on an overnight flight. I wanted to see the Vietnam national team before any tournament began, because I believe a team is built in empty training sessions, not in packed nights. The first session I watched ran for more than one hour and forty minutes. Kim Sang-sik split the squad into three small groups, each working on a different combination, and what caught my attention was not the shape but the number of times he stopped to speak privately to a player. Eleven times. I counted. None lasted longer than forty seconds. The rhythm of the session did not change because of those stops. That is the mark of a man who understands that words must travel with the movement of feet, otherwise they are only noise. Every player has his own rhythm. I only look for where it begins. I found where it begins in the corridor leading to pitch two, at 16:50, when Nguyen Quang Hai and Nguyen Hoang Duc stood and waited for each other for three seconds before walking out. Those three seconds appear in no coaching manual. Those three seconds are what I wrote in my notebook, underlined twice. In December 2026, Vietnam entered the ASEAN Cup. They beat Indonesia in the group stage, beat Myanmar in the semi-final, then met Thailand in the final. The first leg in Bangkok ended 2-1 to Vietnam. The second leg in Hanoi on January 5, 2026 ended 3-2 to Vietnam, a 5-3 aggregate. It was Vietnam's third Southeast Asian title, after 2026 and 2026. But what I remember most from the night of January 5, 2026 is not the trophy. It is Nguyen Xuan Son lying on the pitch. The naturalised Brazilian-born striker had completely changed how Vietnam attacked throughout the tournament and finished as the competition's leading scorer. He scored in the first leg, and in the second leg, at exactly the rhythm the whole team had learned to run to, his leg broke. My Dinh fell silent for nearly two minutes. Then the stands sang. I wrote in my notebook: they sang not to celebrate a victory, but to keep a player lying on the grass from feeling alone. I had seen a similar moment in Kazan, in June 2026, at the World Cup. South Korea beat Germany 2-0, Kim Young-gwon scored in the 90+3rd minute, and I was among the first to catch the words of the South Korea head coach after the match: they won because the players trusted each other. That line has been reused so often in bulletins that it has become a cliché. But I stood four metres from where he said it, and I know the man was not being clichéd. He was trying to explain something the scoreboard could not explain. After the tournament in Russia, I flew straight to Jakarta and followed Vietnam's U23 team under coach Park Hang-seo for two weeks, recording how he used a 3-4-3 that shifted according to each opponent and each shift in his players' mental state. Those two weeks taught me that a formation is not a blueprint. A formation is a way of talking. Back to Kim Sang-sik. What I tracked in his sessions through 2026 and 2026 was not purely tactical. I tracked how Vietnam responded in the first fifteen minutes after conceding. That is the only metric I trust, and it appears on no statistics page. Before March 2026, after conceding, Vietnam typically needed seven to ten minutes to recover their structure. The ball circulated more sideways, the lines stretched, and the holding midfielder dropped almost into a third centre-back. Once Kim Sang-sik stabilised the side, that period fell to roughly three to four minutes in most of the matches I attended. My method is crude: I start a stopwatch when the ball hits the net and stop it when the team completes three consecutive passes along the line the coach has demanded. Those three passes are the sign of a collective that has found its rhythm again. Not of a collective playing better. Playing better is a matter for individuals. Finding rhythm again is a matter for the whole team. Vietnam under Kim Sang-sik played with a back three in most matches, with two wing-backs covering both ends. The interesting part lies in how those wing-backs combine with the central midfielder, not in whether the number is three or four. When the ball is on the left, the central midfielder shifts left, almost level with the left-sided centre-back. When the ball switches to the right, he does not chase it. He stands still and waits. That pause lasts about two seconds, and it is what creates the entire structure. A central midfielder who moves out of rhythm turns a back three into a back five sitting deep in their own half. I rewatched the footage of four Vietnam matches in late 2026 and early 2026 to verify this. In three of the four, Vietnam's goals began with a phase in which the central midfielder stood still for exactly two seconds before passing. Not the decisive pass. The silence before the pass is what opened the space. This is the kind of detail no data table records, because a data table counts only what happens, while what decides a match is the time before it happens. At the same time, in South Korea, the sports press wrote a great deal about Vietnam hiring a K League coach. The common reading here was: Vietnam wants to learn from Korea. I believe that reading is backwards. Busan is not the spotlight, but it taught me how to keep rhythm. Years of living here taught me that Korean football does not export its rhythm. It exports its method. A Korean coach brings to Vietnam a way of organising a session, a way of splitting groups, a way of asking players questions. The rhythm has to be found locally. And Vietnam's rhythm is produced by things that are very hard to copy: the patience of families, the atmosphere of matches in provincial stadiums, and the way a nineteen-year-old sits in a dressing room, frightened and silent, then stands up when his name is called. In two years of following this team, I noticed something I never saw in the K League: in Vietnam, a training session can lose its rhythm simply because one player has a family problem. In Korea, the player goes quiet and trains on. In Vietnam, his teammates stop, and the session slows for about thirty seconds. Then everything returns to normal. But those thirty seconds are real, and a coach who can read them will build a team; a coach who cannot will call it unprofessional. This is the part I believe outside analysts most often get wrong about Vietnamese football. Success is usually explained by a single factor: a good coach, or a good naturalised striker, or a golden generation. The truth is simpler and harder: a collective only rises when it has someone responsible for keeping the rhythm on the days nobody is watching. That rhythm-keeper, in most cases, is not the star. At a training session in September 2026, the rhythm-keeper I observed was a player who rarely starts. He had a minor ankle problem, trained separately on the touchline, and all session long he counted the running beats of each teammate out loud. His teammates laughed. But by the sixtieth minute, the whole squad had switched to a drill based on those beats. He turned a joke into a tool. That camp left me another note I have never published: on one occasion, two assistant coaches argued quite sharply in the corner of the pitch about whether to keep a player back after training. They spoke quietly, but I was standing close and heard them. Ten minutes later, that player stayed behind, practising long passing alone, and head coach Kim Sang-sik stood at the opposite edge of the box watching. He said nothing. He simply stood there for thirty-five minutes, arms folded, like a man holding a door open for a training session with no audience. Not every match has an audience. But every match has someone keeping the rhythm. Now comes the part I consider most important in this piece, and also the part most easily misread. After the defeat to Indonesia on March 26, 2026, Vietnamese football analysis forums filled with one kind of number: expected goals. The argument ran that Vietnam created more chances than Indonesia, that the metrics were unlucky, that the team had been unfortunate. Those tables were shared thousands of times, carrying with them a sense that the national team had been judged unfairly. I do not use expected goals to explain a defeat. Not because I cannot read it. Because I sat in that stadium and saw something the metric cannot capture: in the twentieth minute, after conceding, the shoulders of the Vietnamese players dropped by about two centimetres. I know this detail sounds exaggerated. But I have been recording things like this for more than twenty years, and I trust it more than any post-match metric. When the shoulders drop, short passes become slower by roughly a quarter of a second. A quarter of a second is something machines cannot judge as good or bad, but for a defender already standing in the right position, it is enough to intercept. Expected goals does not measure that quarter second. It measures the final shot and assigns it a probability calculated from thousands of other shots, by other people, in other atmospheres. I oppose the use of expected goals as an explanation for match decisions, for player form, and especially for refereeing standards. The metric describes data, not people. A player dealing with a family crisis carries the same expected-goals figure as that same player at his peak. On the pitch, they are two different players. The same holds for referees, and here I want to be direct. After video assistant referee technology spread across Asian competitions, many expected controversy to disappear. My observation is the opposite. The technology did not reduce controversy. It moved controversy off the grass and into the review room and into the grey zones of the law, where the answer depends on which frame is chosen at which moment. A crude example: in one Asian qualifier I followed, a handball in the penalty area took four minutes to resolve. Those four minutes were four minutes in which the stands did not know what was happening, players were not allowed to leave their positions, and coaches were not allowed to speak to their own players. Whether the final decision was right or wrong matters less than the fact that the audience spent four minutes understanding nothing. A sport cannot run long-term by asking viewers to believe in something they are not allowed to see. In Vietnam, refereeing controversies are usually read emotionally: we were cheated, we were treated unfairly. I do not follow that line. The problem lies elsewhere: semi-automated offside and current handball rules are built to protect accuracy, but they are not built to protect continuity. Football lives on continuity. A match cut into ninety separate fragments is no longer a match; it becomes a record of proceedings. And this is the part I believe Vietnam will have to face sooner than the rest of the region. While debates about referees and metrics continue, a large share of young Vietnamese viewers have moved to esports. I follow this trend not because I care about the games, but because I care about structure. Esports competitions move faster, update their rules more frequently, and carry fewer control mechanisms than traditional sports. Betting in those competitions is eroding competitive integrity faster than football ever experienced, and current regulation is not keeping pace. I say this as someone who has spent years reading integrity reports: there will come a time when Vietnamese football learns from esports, but it should learn from esports' mistakes, not from its model. If football waits until the problem is obvious, it will be dealing with a generation of fans already accustomed to doubting every result. During the two weeks I followed Vietnam's U23 team under Park Hang-seo in Jakarta in 2026, I wrote a line in my diary that I have reread many times since: this team is not strong because it has good players, it is strong because in the dressing room there is someone willing to say sorry first. I believe in a version of Vietnamese football like that. Not a football explained by data tables, but by whether the players still stand in a corridor and wait three seconds for each other. So what is the next internal signal to watch? It is the first fifteen minutes after conceding in the next competitive match Vietnam has to play. If vertical passes still appear in that window, if the central midfielder still stands still for the right two seconds instead of dropping deep, then the internal engine is still running. If not, no metric will save that match. And if anyone asks me what I trust more, a post-match data table or a 4 p.m. training session nobody is watching, I will not hesitate. A Korean cries over Vietnamese football. That is the shared rhythm. Whether that shared rhythm can be kept, the next match will answer for all of us.
