V-League On-Field Violence: When Referees Miss Cards, the League's Discipline Collapses on Itself

Late on September 20, as the match between Dong Nai and Cong An Ha Noi (CAHN) entered its final minutes, I sat in front of a screen in London with the Vietnamese clock already past midnight. The ball had long gone the other way. Nguyen Dinh Bac went down. Full-back Le Van Son had just finished an elbow into the chest of the opposing striker, in a spot where the crowd had stopped following the ball.

Minutes later, centre-back Huynh Tan Sinh kicked Dinh Bac's legs from behind. The first time. Then the second time. Referee Le Vu Linh showed a yellow card.

In more than thirty-five years of watching football, I have learned one thing: the discipline of a league is not measured by the heaviest sanction it announces, but by the lightest card a referee hesitates to brandish. A league loses control not on the day a player breaks his leg. It loses control weeks earlier, in silence, in the moments nobody films.

Everything in football is transition, including for those not good enough to understand it. And the worst transition is not a broken counter-attack. It is the moment a player decides that football is no longer a game of the ball, but a game of fear.

A chain, not an incident

What makes the September 20 story different from an isolated collision is that it does not stand alone.

Not long before, in Round 2 of V-League 2026-2027, CAHN centre-back Doan Van Hau broke the leg of The Cong Viettel midfielder Doan Ngoc Tan. In the same round, Nam Dinh foreign player Ezequiel Santos Da Silva stamped on the stomach of Vo Huu Viet Hoang of SHB Da Nang. Four names, three incidents, two rounds, a season barely underway.

At first, each could be read as a separate accident. Van Hau broke a colleague's leg in a strong challenge. Ezequiel stamped during a duel for the ball. Son elbowed Dinh Bac after the ball had gone. Tan Sinh kicked twice. Each act had its own context, yet they share a common denominator: every one of them is behaviour the laws of football already anticipate and already punish.

When behaviour that already carries a punishment keeps recurring within a short span, the problem is no longer individual morality. It sits in the enforcement system.

By then, representatives of the organising committee, VPF and VFF had met directly with the VFF Referees Board. In that meeting, the parties demanded that referees apply the laws properly, preserve the league's discipline, and stop brutal conduct on the pitch. The phrase apply the laws properly sounds simple. But translated into the language of a referee holding a whistle in the middle of the pitch, it means something far more specific: do not miss fouls, do not miss cards.

I once attended a youth match in London where the stand held only a handful of people, me among them. No VAR, no slow-motion cameras, no thousands of fans screaming. Just a sixteen-year-old boy kicked from behind, and a young referee standing three metres away, hesitating half a second before blowing his whistle. That half-second was the entire disciplinary foundation of the match. When that referee blew on time, everything stayed intact. When he let it go, an entire cohort learned that violence is cheaper than patience.

Responsibility does not stop with the man holding the whistle

Referee Le Vu Linh missed a card on Huynh Tan Sinh's challenge. That conclusion came from Duong Vu Lam, former VFF Vice President for professional affairs and former head of the VFF Referees Board, speaking to Dan Tri reporters after the match.

He said: Referee Le Vu Linh missed a card on that challenge. Huynh Tan Sinh's kick off the ball was far too blatant, yet it did not draw a red.

Reading that, what struck me was not the phrase missed a card. It was the phrase far too blatant. A foul so blatant that anyone inside the stadium could see it, a foul whose perpetrator did not even bother hiding it, failed to draw the heaviest card. When discipline cannot keep pace with how blatant the behaviour is, players learn a very concrete lesson: the risk of punishment is lower than the benefit of stopping an opponent by any means.

But Duong Vu Lam did not stop with the on-field referee. He widened the question: if Tan Sinh is to be retrospectively banned for this foul, then referee Le Vu Linh should have his whistle suspended in the same way. He extended responsibility to the VAR team of Vo Hoai Thuong and Nguyen Thanh Son. According to him, if the VAR team advised the on-field referee but the on-field referee overruled them, then the VAR team did its job. Conversely, if the VAR team failed to advise referee Le Vu Linh that a red card was required for the kick off the ball, then the VAR referees should also be sanctioned.

That is a notable way to frame the problem, because it turns an individual mistake into a systems question. When a foul is plain for an entire refereeing team to see, a team that includes three people and several slow-motion angles, where exactly did the failure occur?

The VAR mechanism was designed to do one job: correct clear and obvious errors. A kick off the ball delivered twice into an opponent's legs, in an area where the on-field referee has a good view, sits squarely in the clear-and-obvious bracket. If the on-field referee waved it off and VAR did not intervene, the system let through exactly the type of error it exists to catch.

I have watched hundreds of VAR-equipped matches in Europe, and the lesson I keep drawing is simple: VAR can never fix a referee who does not want to be fixed. If the on-field referee believes Tan Sinh's challenge merits only a yellow, no amount of camera angles will easily change his mind unless the VAR team is brave enough to call him to the monitor. And whether VAR is brave enough to call depends on something far harder to measure: the reflex of protecting a colleague.

That is why I hold that the responsibility here is not merely a matter of suspending one person. It is a matter of process transparency. When sanctions are not published, nobody knows what the VAR team did, nobody knows whether the on-field referee was reprimanded, and nobody learns anything from the error.

Duong Vu Lam himself acknowledged this mechanism: specific disciplinary rulings against referees are usually not publicly announced, but watching the referee appointments for the following rounds tells you whether the referees in question have had their whistles suspended. If they are not assigned in the rounds immediately after the round just played, it is highly likely they are being disciplined.

That mode of operation has a built-in weakness. It turns enforcement into an underground activity, where fans can only infer through absence. A disciplinary system whose punishment is invisible loses half its deterrent power. Players do not see referees being sanctioned, so they do not believe the mistake will carry a price. And if they do not believe that, they will keep recalculating the cost-benefit equation before every challenge.

What a young player learns from a yellow card

My trade is player development consultancy. My job is not to teach a child to kick a ball, and it is not to declare who is better than whom. I do not train players. I excavate what they already were, before the world told them who they had to be.

In that work, I have learned that a young player does not absorb discipline through lectures, but through the repetition of consequences. If a bad act is witnessed every week without sufficient punishment, it is written into the memory of an entire cohort as a legitimate skill.

I once sat in a scouting room in England where a colleague reviewed clip after clip of a young midfielder. When the footage reached a boy being kicked from behind with no card shown, he said something I have never forgotten: this boy has just learned that nobody will protect him. From that moment on, the boy will protect himself first. And the way a young player protects himself is usually to learn to retaliate, to kick off the ball, or to play safe so he does not get kicked.

All three roads lead away from beautiful football.

That is why I treat every missed card in V-League as a cascading loss. It damages one person today. It alters the behaviour of hundreds of youth players downstream, the ones who watch those matches and draw their own conclusions.

The social feedback loop is a cruel coach—it never sleeps and never forgives.

In 2026, during the period of empty stadiums, I had the chance to watch many youth matches with no spectators. There, I saw very clearly what big matches usually obscure: violence is not the essence of youth football. It is a learned response, appearing when a child feels unprotected. A young player only kicks off the ball when he believes that is the only way to survive on the pitch.

When a transition from defence to attack is snapped by a kick to the legs, the natural reflex of a child is not to get up and keep running. The natural reflex is to remember, to guard, to change posture, and gradually to avoid the challenges that require courage. A violent league does not only produce aggressive players. It also produces fearful ones, players who play not to get hurt rather than to make a difference.

And the second type is often harder to detect. They generate no highlights. They do not appear in clips of pretty numbers. They quietly drop out of football at twenty because nobody realises their reticence began with a missed card at seventeen.

This is the part statistics never reach. Distance covered, number of sprints, number of successful duels—all are packaged as measures of effort. But a player who runs eleven kilometres in fear and a player who runs eleven kilometres in confidence share the same number. Data only has value when it explains what the eye already caught. When it hides fear, it is no longer evidence; it is a curtain.

The contrarian angle: what sanction, and how, is the harder question

When a wave of violent incidents breaks, the familiar public reaction is to demand a heavier punishment. A longer ban. A bigger fine. A sacked referee. That is an understandable emotional response, but it usually overlooks an uncomfortable truth: the heaviest sanction has never been the most effective deterrent.

Across many seasons I have followed, the club applying the harshest penalties is rarely the cleanest-playing one. Sometimes the opposite. When every foul can be punished at the maximum level, players do not play more carefully; they play more covertly. They shift from kicking legs to subtle nudges, to shoves where the referee is not looking, to calculated kicks off the ball.

That is precisely what Dinh Bac endured. Le Van Son's elbow came after the ball had gone. Tan Sinh's kick off the ball was repeated twice. These are not acts of anger bursting out during a duel for the ball. These are acts with time to think. And when a player has time to think about hurting a colleague, the problem lies elsewhere, not in impulse.

It lies in the player believing he will not be caught.

So my contrarian view is simple. Heavily sanctioning referee Le Vu Linh is necessary, but by itself it does not save the league. What saves a league is the consistency and visibility of sanctions. A red card drawn correctly in the seventieth minute deters more than ten bans announced with fanfare weeks later.

There is a detail in how V-League handles discipline that I think deserves discussion. Referee sanctions are usually handled quietly, through their absence from the next round. That mode protects the referee's personal reputation, but it damages the credibility of the mechanism itself. Fans do not see justice done. They only see a name vanish from the appointments list.

If a league wants to send a strong signal, that signal must be visible. It need not name names with detailed penalties, but it needs a statement clear enough that players, referees and supporters all understand that errors carry concrete consequences, and that those consequences apply to both sides: the one who committed the foul and the one who missed it.

That is the line between a mature league and a league still fumbling its way. A mature league does not need to look strict every time an incident occurs. It only needs to operate strictly every day, including the days nobody films.

I know I may be asking for more than a developing league can deliver immediately. But I also know the same has happened elsewhere. Leagues once regarded as violent reformed themselves, not through a grand campaign, but through thousands of small, steady, quiet decisions—including decisions to sanction the man holding the whistle.

What remains after the storm of discipline

I once told a colleague in Vietnam that Vietnamese football has reached a stage where its technical quality has overtaken its governance quality. He laughed and said I was too optimistic. Perhaps. But looking at how VFF, VPF and the organising committee sat down with the Referees Board after the chain of incidents, I see at least one real signal: they know where the problem is, and they know it must be stopped before it seeps into the lower tiers.

The difficulty of stopping violence in a league is that its best outcome is silence. When everything runs correctly, there is no bad challenge to discuss, no viral clip, no emergency meeting. Nobody praises a league for the violence that did not happen. But that silence is precisely what is worth pursuing, because it is the environment in which young players grow up without learning to fear their colleagues.

Dinh Bac will recover. Van Hau will return after his sanction. Tan Sinh may be banned. Referee Le Vu Linh may not appear in the coming rounds. All of that will pass, and within weeks another incident will replace it in the headlines.

What lasts longer is the memory of children. They will remember that in this season, an elbow to the chest and two kicks to the legs were answered with a yellow card. They will draw their own conclusions, and those conclusions will shape how they play football for the next ten years.

If the league's organisers want to change something, the moment to change is not the next round. It is how they handle this incident—openly or quietly, consistently or on a whim. Because a league's discipline is not built in emergency meetings; it is built in the moments nobody watches, on near-empty pitches, and in the times people choose not to look.

When only three people remain on the pitch, the discipline of an entire footballing culture rests in the decision of the fourth, the one holding the whistle. That is what I saw long ago, and what I still believe today.
