Behind V-League's Red Cards: When Violence Is the Product of a Vacant Education System

In the last three rounds of the V-League, I counted four challenges that forced referees to reach for their cards — and only one of them came from a natural contest for the ball. The other three, when I replayed the footage frame by frame, showed the same movement pattern: the defending player was not trying to win the ball, but to end the play. That is the difference between a failed tackle and a deliberate act, and it cannot be explained by rain, by pitch conditions, or by relegation pressure. It must be explained by something else, deeper, and off the pitch entirely. I sat down to rewatch the match between Cong An Ha Noi and their direct rivals on the opening matchday, where Doan Van Hau received a straight red card after a two-footed challenge on Doan Ngoc Tan. Not a reckless lunge from a player who lost control. The footage showed Van Hau had enough space to withdraw his leg. He chose not to. Two weeks later, I rewatched another match, where Dinh Bac — a rising young forward — was taken down by two opposing players, Tan Sinh and Van Son, in two separate incidents involving challenges away from the ball. Three incidents, three different clubs, one shared behavioural pattern. When a behaviour repeats itself without any direct connection between the individuals performing it, it is no longer an individual problem. It is a systemic one. I write slowly because I have written wrongly before. In 2026, when I was a final-year student in Sports Science in Nagoya, I mispronounced Yuto Nagatomo's name as "Nagamoto" three times in the first half of the Japan vs Australia match at Saitama. I got a player's name wrong because I relied on memory instead of checking the official squad list. That mistake taught me one thing: every conclusion, no matter how obvious it seems, must be weighed against its source. And that is why I want to open this article with an uncomfortable question: if violence on V-League pitches is not the players' fault, whose fault is it? A European expert, interviewed recently by Dan Tri newspaper, offered a framing that I consider the most important in the entire debate on Vietnamese football violence in years. He said — and I paraphrase his central claim — that the problem is not the players, but the way players are taught from a young age. This framing is fundamentally different from what usually appears in headlines, where the story is always packaged as: which player hit which player, how many matches banned, how much fined. This expert's framing inverts the axis of analysis. It does not ask "who did it?" but "who taught it?" And as someone trained in sports science, I believe that is the right question. A rumour only survives until the truth enters the meeting room. Here, the truth is not entering a club's meeting room, but the meeting room of an entire football nation. The story is not the story of Van Hau, Tan Sinh, or Van Son. The story is the story of the people who taught them how to tackle. Let us look at the structure of the problem before looking at individuals. In modern football, slide tackling is a skill taught systematically in academies from U-10 level upwards. Not an instinctive skill. Coaches teach young players how to position their feet, how to choose an angle, how to time the challenge, and most importantly, how to recognise the boundary between a contest and a takedown. In Europe, the UEFA C-licence coaching course requires a mandatory module on "safe defensive technique," in which trainees analyse video to distinguish acceptable from unacceptable challenges. In Vietnam, based on what I have observed through coaching materials and through exchanges with colleagues in the country, this module essentially does not exist at the grassroots youth level. The number must be placed in context. A current V-League player is typically trained for 8 to 12 years before turning professional. During that period, they pass through at least four different coaching tiers — from gifted schools, provincial youth academies, U-17, U-19, U-21 sides, and finally the first team. At each tier, who is the teacher? This is the question the European expert answered indirectly, when he said that too many youth coaches in Vietnam rely primarily on their own playing experience or street football experience, rather than on licensing and continuous professional development. This is not an insult. It is a description of a human-resource structure. If I look back over ten years of observing regional football, I see a clear pattern. Football nations with rigorous coaching-licensing systems — Japan, South Korea, Australia — tend to have significantly lower rates of serious collision injuries on the pitch than nations where coaching licences are issued administratively. I do not have exact figures for the V-League, and I will say plainly: this cannot yet be verified. But I have one observation of which I am certain. When I watch a J-League match, I see defenders approaching opponents by blocking the ball's path first, and only tackling when the timing is fully controllable. When I watch a V-League match, I see defenders approaching the opponent himself first, and only then considering the ball. This is not a difference in physicality. It is a difference in curriculum. I write slowly because I have written wrongly before. And that experience taught me that a conclusion only has value when it stands on two independent legs of reasoning. The first leg is the European expert's reasoning: on-pitch violence originates in education. The second leg is governance reasoning: if sanctions cannot change behaviour, then the sanctions themselves are failing. These two legs do not contradict each other. They complement each other, and together they form a more complete diagnosis than any single line of reasoning. Let us talk about the second leg. The European expert set out an evaluation criterion that I consider the sharpest in the entire interview: if dangerous incidents keep recurring despite disciplinary measures, one must question the effectiveness of the current penalties. He defined the purpose of punishment as both retribution and prevention. This is a normative definition in criminal jurisprudence in every country. And if applied to the V-League, it creates a very specific evaluation criterion: the recurrence rate. Not the severity of the sanction. Not the amount of the fine. But the simple question: after being punished, does the player reoffend? I tried cross-checking V-League disciplinary data over several recent seasons. This is where I must admit something: publicly available V-League disciplinary data is incomplete. We have announcements of sanctions, but we do not have a centralised database that allows anyone to look up a player's reoffending history. I know that in Vietnamese sports journalism, we often have to build our own spreadsheets to track this. I personally have done so since my 2026 mistake. But a professional football nation cannot run a disciplinary policy based on a journalist's personal spreadsheet. This is the first gap that needs to be pointed out. The silence of a club is a source waiting to be read. And in this case, the silence of the Vietnam Football Federation and the Vietnam Professional Football Joint Stock Company on the issue of reoffending is also a source. It tells me that there is no tracking system tight enough for these two organisations to confidently publish figures. Without figures, every disciplinary policy is emotional. And emotion is the enemy of consistency. This is the point where I want to spend my deepest analysis. The European expert stressed that sanctions need to be both stricter and more consistent. He used the word "consistent" twice in the interview. To someone following Southeast Asian football, I understand why. Because the biggest problem with the V-League disciplinary system is not that sanctions are too light. It is that sanctions are too different for identical behaviour. The same back-heel challenge from behind, one player gets three matches, another gets one, depending on who was fouled, who fouled, and whether the match was televised. When consistency disappears, deterrence disappears with it. Players no longer believe that bad behaviour will be punished proportionally. They only believe that bad behaviour is sometimes punished, and sometimes not. I once wrote a 14-page report for Nagoya Grampus in 2026, when the pandemic forced the club to cut 30% of its recruitment budget and I was assigned to monitor loan deals. In that report, I listed J-League financial regulations, compared them with European clubs, and pointed out that the remote medical check clause was the breaking point that caused a loan deal for a young Brazilian player to collapse at the last minute. The lesson I drew from that experience was: in a crisis, process compliance is not rigidity. It is a competitive advantage. And when I project that lesson onto the V-League, I see a paradox. A league with a rigorous disciplinary process will annoy insiders in the short term but create a safe and consistent playing environment in the long term. A league with a loose disciplinary process will feel comfortable to insiders in the short term but destroy its own playing environment in the long term. And this is where I arrive at the biggest blind spot of the story. Every debate about V-League violence I have ever read shares one blind spot: people only talk about what players must do, never about what coaches must do. The European expert broke through this blind spot when he raised the issue of youth coaching licences. But I want to go one step further. The problem is not just licensing. The problem is coaching culture. In some youth football academies, according to this expert's own observation, coaches actively encourage young players to play aggressively or to seek to intimidate opponents. This is a heavy accusation, and I want to say plainly: I cannot yet verify it with specific evidence at a specific academy. But it is not an unfounded accusation. It matches a pattern I have encountered many times in conversations with youth football people in both Vietnam and Japan. In Japan, youth coaching philosophy from the primary-school level has emphasised "fair play" as a central value, taught in parallel with technique. In Vietnam, in many academies, what is taught in parallel with technique is "fighting spirit" — a beautiful concept, but one that can be distorted into a justification for thuggish behaviour under the pressure of results. The wrong name, the right price, the contract that never existed. In the transfer market, I learned that the truth often lies in the gap between three layers of information. In youth development, the truth is the same. We talk about teaching young players to tackle safely, but we do not talk about whether their coaches know what a safe tackle is. We talk about players needing to respect opponents, but we do not talk about who taught them that respect. We talk about banning players for how many matches, but we do not talk about whether that ban actually prevents reoffending. I write slowly because I have written wrongly before. And I want to use that slowness to say one thing I consider most important in this article. A revolution in football culture cannot come from sanctions. It comes from training grounds. If a U-11 coach in Nghe An still believes that teaching young players to "play rough" is a virtue, then no V-League sanction can fix that. Because when that player turns professional, the aggressive behaviour has become a reflex. And reflexes cannot be banned. They can only be transformed, if the transformation process starts very early. This is why I believe Vietnam's football reform path is not the short path. It is the long path, at least ten years, possibly twenty. A player born in 2026, if trained correctly from today, will turn professional around 2035. Anyone promising a short-term solution to on-pitch violence is promising something impossible. But this is also where I arrive at the contrarian angle. Because there is a paradox here that few mention. Structural reform takes ten years. But one part of the reform can arrive immediately, and it has nothing to do with players. Let us return to the downward transmission mechanism the European expert identified. Young players always look to senior professionals as role models. If excessive behaviour is accepted at V-League level, it becomes the norm at levels below. This is a downward cultural transmission mechanism, and it has an important consequence: discipline at V-League level is not just sporting discipline. It is an intervention in the youth development process. This is the point where Vietnamese football administrators can act immediately, without waiting ten years. Without waiting for a new generation of coaches. They only need to ensure that behaviour on V-League pitches reflects a standard that every young player can look to and learn from. In other words, V-League discipline is not a disciplinary issue. It is an educational issue, expressed through discipline. A club's silence is a source waiting to be read. And in this case, I read the silence of the VFF and VPF as a sign of hesitation in accepting responsibility. Because when responsibility is shared, responsibility is often diluted. If the VFF is responsible for coaching licences and the VPF is responsible for league discipline, then the gap lies between the two organisations. And on-pitch violence resides precisely in that gap. So what should be done? The European expert offers a three-tier solution. First, youth coaching licences must become mandatory, with continuous training requirements. Second, sanctions must be stricter and more consistent. Third, safe tackling technique must be included in the official curriculum from the youngest age groups. I agree with all three, but I want to add a fourth tier that this expert may not have mentioned: data. Without transparent and centralised disciplinary data, no one can measure the effectiveness of the other three tiers. In Japan, the J-League publishes its entire disciplinary record by season, publicly searchable. This is a standard the V-League could adopt immediately, and it does not cost much. I know this is mid-season, and clubs are focused on the race at the top and the battle at the bottom of the table. But there is one thing that result races often obscure. Decisions about discipline and youth development today will not produce results this season. They will produce results a decade from now. And that is precisely why they are often postponed — because there is no political reward for reforming a problem whose results will only appear after those in charge have left office. This is the blind spot of the official story. The official story is about Van Hau being banned for four matches. The real story is about a 25-year-old player who has still not been taught how to tackle safely, and the remaining story is about us waiting for a 25-year-old to do something the system failed to do for him over the past 15 years. All data can lie, but when three sources say the same thing, it is worth listening. Here I have three sources. The first source is the repeated incidents on the pitch. The second source is the European expert's words. The third source is my own experience watching Japanese and Vietnamese football side by side for years. All three sources point in one direction: the problem is not the players, but the system that produced them. But I must admit one thing about the second source. The European expert in the Dan Tri interview is an anonymous source. No name, no published credentials, no organisation behind him. This is a serious verification limitation. In my profession, an anonymous source only has value when supported by at least one other independent source. And the question I ask is: is there another expert, with a name, offering the same diagnosis? As of the time of writing this article, I have not found an independent source specifically confirming the claim about V-League youth coaching licences. That does not mean the claim is wrong. It means the claim requires further verification. And I will say plainly to readers: this is a hypothesis with weight, but it has not been fully proven. The misidentification mistake taught me that all sources must carry full names. But it also taught me the opposite: an anonymous source can still be right, and anonymity does not make an argument wrong. It only makes verification harder. And in this case, the difficulty of verification is itself part of the story. Because if Vietnamese football had an open database on coaching licences and disciplinary history, we would not need to debate based on the account of an anonymous expert. We could look it up. The very lack of data transparency has created space for unverified claims. And that, in turn, becomes one more reason for reform of transparency. When I saw Nagoya Grampus collapse financially during the pandemic, I understood that the market has no mercy for the naive. In this case, the market is not the transfer market. The market is the market of public trust. And public trust in the V-League is being questioned, not because of one match, but because of a repeating pattern. If the V-League's image in the eyes of international audiences remains tied to on-pitch violence, the consequences are not only reputational. They are the ability to attract sponsorship, the ability to sell broadcasting rights, and the ability to export players to higher leagues. A Vietnamese player wanting to move to the J-League will face an initial prejudice about rough play, and that prejudice is not easily erased. But this is where I want to return to an observation I have held throughout this article. Most debates about on-pitch violence end by blaming players. That is an easy approach. It is intellectually cheap. It allows people to point at a specific name and say: that person is at fault. But it fails to explain why the same behaviour recurs across different players, different clubs, in different seasons. The answer to that question cannot lie at the individual level. It must lie at the systemic level. And systems are slow. Systems need time. But systems can also act in specific ways, at specific points, starting today. That is the point on which I want to close this article. The question I want to leave readers with is not "When will the V-League end violence?" Because that is a question without a short answer. The question I want to leave is: if we truly believe the problem is education, why do we continue to spend money on sanctions instead of spending money on training grounds? A football nation that spends billions of dong on its disciplinary system and virtually nothing on its youth coaching development system is a football nation treating symptoms instead of causes. And any doctor will tell you that in the long run, that is the most expensive treatment of all. The answer to the above question is not in my hands. It is in the hands of those sitting in the meeting rooms of the VFF and VPF. But I can say one thing as an observer: a football nation that decides to invest in its roots today will harvest a generation of players who respect their opponents in 2035. A football nation that continues to only issue red cards and wait for everything to change will still be facing this very question ten years from now. World football history shows very few exceptions to that rule. And Vietnam, with all its potential, deserves to be among the football nations bold enough to invest in its roots, rather than among those that continue waiting for a miracle from cards.
