VAR in V.League and the Discipline of Waiting for Evidence Among Vietnamese Referees

The 74th minute of a match at Hang Day Stadium. The ball hits a hand inside the penalty area. Forty thousand people rise to their feet in the same second, and most of them have already reached a verdict before the ball has rolled out of play. The referee has not. He stands still, one hand raised to his earpiece, eyes fixed on the point of contact, waiting for a voice to arrive from a room a few hundred metres away. The distance between those two verdicts belongs to duty, not to technique. The stands are allowed to conclude instantly. The referee is not. In the refereeing profession, concluding before the evidence is the most serious professional error a man in black can commit, because it destroys the only thing that gives a whistle its weight: consistency. I spent ten years living inside refereeing before moving to the other side of the screen. Those ten years taught me that the hardest part of the job lies in waiting for enough evidence before saying what you have seen. When the input file is empty, the only correct answer a professional is permitted to give is: insufficient information to assess. That sounds simple. But amid forty thousand voices, it is the hardest decision of the working day. A young system, a pressure that is not young Video assistant referee technology (VAR) arrived in V.League 1 from the 2026 season, following training courses organised by FIFA and the AFC together with the Vietnam Football Federation. The league runs with 14 clubs in a double round-robin format, amounting to more than 180 matches per season. Every one of those matches contains hundreds of decisions: a throw-in in the third minute, a collision nobody remembers in the 40th, a yellow card in the sixth minute of stoppage time. Human resources are far thinner than that workload. The number of Vietnamese referees named on FIFA's annual international list amounts to only a handful in each category — centre referees, assistant referees, futsal referees, women's football referees. A country with tens of millions of fans, a professional national league, and a national team that has reached the third round of World Cup qualifying still has only a small group of officials operating at international level. Meanwhile, the collective memory of Vietnamese football is built on enormous emotional peaks: the U23 side reaching the 2026 AFC U23 Championship final, then the AFF Cup titles of 2026 and 2026, with the second leg of the 2026 final at Rajamangala Stadium where Nguyen Xuan Son suffered a broken leg. Those peaks nourish expectation. What is striking is that those same peaks set an implicit standard for domestic referees. When the national team wins, fans see Vietnamese football as having reached a different level. Back in V.League, they carry corresponding expectations — and a disputed incident in round 12 suddenly gets judged by the yardstick of a regional final. That mismatch in standards is the source of much of the criticism referees absorb. The Laws of the Game that every Vietnamese referee must follow are issued and updated annually by IFAB. Under them, VAR may intervene in only four categories of incident: goal or no goal, penalty or no penalty, direct red card, and mistaken identity. The intervention threshold is a clear and obvious error, or a serious missed incident. This is the point most spectators have never read closely. Dissecting a decision in thirty seconds A controversial incident does not begin on a screen. It begins with where the referee is standing. A good referee does not chase the ball. He runs toward where the ball is going, choosing an angle so that when the situation erupts he is already in the right place, at the right distance, with the right eye level. In a challenge inside the penalty area, the gap between the right position and the wrong one is only a few metres, but the difference in information gathered is enormous. Then there is the assistant referee. A flag raised in the 89th minute looks simple, but behind it sits a chain of calculations: the attacker's position at the moment a teammate touches the ball, the part of the body permitted to score, and the tolerance level that semi-automated offside systems accept. There is one thing the offside trap can never catch: the player's intention. The law measures position, not intention — and that very gap generates most controversies. The four categories open to VAR intervention sound narrow, but in practice they cover almost everything that causes dispute: goals and the phases leading to them, penalties, direct red cards, and cases of mistaken identity. This forces referees to work with two layers of awareness running in parallel. The first layer is what the eye sees in an instant. The second is the likelihood that the incident will be reviewed. Beginners tend to operate only the first layer. Experienced officials operate both — and that is why they stand in a different place. When the referee raises a hand to his earpiece, the conversation happens in a language of its own. The VAR team in the video room announces that it is checking, confirming, inviting the referee to the monitor. Each sentence runs only a few words, following a unified protocol, usually in technical English. For a young referee newly promoted to V.League, this is a barrier rarely discussed: correctly parsing a phrase about an attacking possession phase in an instant is no different from reading a law under pressure. And finally, the hardest ritual: walking to the monitor, reviewing, and then overturning your own decision in front of forty thousand people. The referee must tell the whole stadium that what he just announced was wrong. In this profession, that takes more courage than any other decision. In the trade, the two criteria of correct and consistent are frequently confused. A referee can make a decision that is technically wrong yet entirely consistent with how he handled a similar incident in the 10th minute. A match does not collapse because of a single error. A match collapses when players can no longer predict what the referee will call. Players accept a strict referee. They do not accept an unpredictable one. What VAR exposes VAR does not fix errors for the match — it exposes how we define error. Many fans expect VAR to be a second referee, one who will deliver the correct verdict on every incident. VAR has no such mandate. It is only a review channel, and its intervention threshold is far higher than the stands' threshold for complaint. The consequence: the more cameras there are, the more disputes there are, because people see more without understanding the law any better. The root problem of Vietnamese football lies in the referee development pipeline, not in the number of cameras. When a football nation has only a handful of internationally accredited referees, expanding VAR across every match stretches resources thin. Referees officiate more games, recover less, and have less time to sit and review footage of themselves. Alongside that sits pressure from media and social platforms. An incident is cut into a clip, replayed ten times, and a conclusion appears before the VAR team has opened a second angle. Media devote thousands of lines to one touch by Nguyen Quang Hai, yet almost nobody writes about where the referee was standing three seconds before that phase — the thing that determined most of the outcome. In ten years of officiating, I learned that the best work is the work nobody remembers. There is a risk that rarely gets named: media pressure does not only affect a referee during that match, it affects the next one. A referee criticised for awarding a penalty may, the following round, hesitate to award a similar one. The result is that consistency is eroded from the outside, by the very people demanding it most. Protecting referees from that pressure is part of protecting the laws themselves. There was a period when the league had to play in empty stadiums. With the stands empty, I could clearly hear the ball striking boots — something ten years of refereeing had never let me hear. The ball on the boot, the breathing of defenders, captains calling to each other. Those sounds gave me another way to read a match: by rhythm, by silences, by what never appears on a statistics sheet. A referee must read a match the same way — reading before the ball arrives, hearing before the whistle sounds. I once made a very small and very costly mistake: mispronouncing a player's name on air, and being corrected in front of the whole country. That mistake in Russia did not teach me how to referee correctly — it taught me how to live with my own whistle. From then on, everything I said had to come with a verifiable source. Without a source, I said nothing. That is exactly the discipline a referee must carry into every incident. What should come next Vietnamese football can start with very concrete steps. Publish the audio of the conversation between referee and VAR team after each match, as some leagues already do, so spectators understand how a decision was formed rather than only seeing the outcome. Open a full-time professional referee development pathway, separate from today's semi-professional model. Standardise the teaching of technical English in the Laws of the Game for young referees, because the VAR protocol will not wait for a translator. Above all there is a cultural standard to set: accepting that a system may say there is insufficient information to conclude. For an incident where the camera angle does not show the point of contact, the honest answer is to uphold the on-field decision, not to guess in order to please the stands. A match with no disputed decisions is not necessarily a well-officiated one; it may simply have contained no difficult moments. A match full of disputes is not necessarily a badly officiated one; the referee may have repeatedly chosen the correct intervention threshold in situations where the law allowed him nothing else. The best whistle is the one after which nobody argues. But to get there, Vietnamese football needs to teach its own audience the hardest of all judgement skills: knowing how to wait.
