VAR in V.League 1: Quality Comes from Process, Not Technology

On a weekend evening, as V.League 1 entered its decisive stretch, I stayed behind after the final whistle to rewind a single incident that had brought the whole stadium to its feet. The referee stood nearly twenty metres from the point of contact. The VAR assistant, sealed in a booth, had fourteen camera angles at his disposal. Yet it took almost two minutes before the crowd received an answer. What interests me is not the final verdict, but the silence before it — the interval in which the data begins to whisper but no one has yet chosen to listen. Before VAR speaks, the data has already spoken. That is why I always open any analysis of refereeing with a table of numbers, never with an accusation. Across many years of watching football, I have learned one thing: the emotion in the stands is real, but it is not evidence. And those of us in this profession have a duty to tell the two apart.

V.League 1 is Vietnam's top professional football competition, run under the management of the Vietnam Football Federation (VFF) and the Vietnam Professional Football Joint Stock Company (VPF). In recent seasons, VAR has been introduced in a number of matches, beginning with fixtures of decisive importance. It is a necessary step if V.League is to approach AFC and FIFA standards.

Buying technology is the easy problem. Operating it is the hard one. In major leagues, VAR is not merely a room with fourteen screens. It is a three-layer system: hardware, people, and protocol. Hardware can be purchased. People can be trained. But the protocol — who says what, at what moment, with what authority — is what decides whether an incident is resolved in thirty seconds or three minutes.

Many people assume that once VAR exists, every dispute will vanish. The reality is the opposite. VAR does not erase controversy; it moves controversy from the question "what did the referee see" to the question "what did the referee choose to look at." That is a significant shift, because it turns a problem of eyesight into a problem of process. And process cannot be bought with foreign currency.

I have spent years following V.League matches on television, and what draws my attention is not the clearly wrong decisions. It is the correct decisions that arrive late. A correct decision after two minutes damages football more than a wrong decision in thirty seconds, because it converts trust into doubt. The crowd does not rage because the referee erred. It rages because it cannot understand what is happening. This is the distinction many football administrators overlook: the anger of the crowd comes largely from ambiguity, not from error.

The referee's mistake is not in the eyes. It is in the position, the line of sight, and the sequence of handling. In modern football, a good referee is not one who sees everything, but one who knows he cannot see everything and designs his positioning around that limit. The error is not in the referee's eyes; it is in where he chooses to look.

When I collected the disciplinary data of a full season and analysed referee positioning, the timing of cards, and match reports, I found a recurring pattern: most controversial decisions do not come from complex incidents, but from incidents where the referee stands at a blocked angle. The problem is not poor eyesight. The problem is an obstructed line of sight. When a referee's view is blocked by a player, he does not err from incompetence; he errs because his position was never calculated to handle that situation. In other words, error is a function of position.

VAR was created to fill precisely this gap. But in V.League, VAR is present in only a portion of matches. This creates a paradox: the same incident is reviewed in a match with VAR and left untouched in a match without it. That inconsistency is more dangerous than having no VAR at all, because it leads people to believe that the laws depend on the fixture list. A league can accept that it lacks the money to equip every stadium with VAR. A league cannot accept two teams playing under one law while receiving two standards of justice.

VAR's intervention threshold is "a clear and obvious error." It is a standard that is correct in law but vague in execution. Clear to whom? Obvious from which angle? If the on-field referee and the VAR assistant have not agreed in advance on what "clear" means, each will read the same frame in two different ways. And when two people read differently, the time to decide lengthens while the crowd's trust shortens.

In a modern refereeing team, four officials share a single decision: the referee, two assistant referees, and the fourth official. When VAR appears, the number rises to six. Each has a different angle, a different level of authority, and a different level of pressure. If the communication line between these six is not standardised, then the more people involved, the slower the decision. This is the paradox of numbers in match officiating: adding people does not automatically add accuracy, if a shared protocol is missing.

In 2026, while working as a dedicated disciplinary reporter, I collected every red card of a season and found that home teams received nearly forty percent fewer cards than away teams. The cause was not deliberate bias, but the pressure of the crowd acting on how a referee handles an incident in a split second. VAR, in theory, removes that pressure. In practice, it merely shifts the pressure from the on-field referee to the assistant in the booth. The person in front of the screen is also human. He too can be swayed by whether the match is at home or away, by the scoreline, by the pressure on a team fighting relegation.

Refereeing quality is decided by process, not technology. A process is only trustworthy when it is applied identically in every match, at every moment, for every team. Technology can magnify an image, but it cannot magnify consistency. That is why I do not measure refereeing quality by the number of correct decisions, but by the standard deviation between decisions. A referee may err a few times and still be trusted, if he errs in the same way. A referee may be right many times and still be doubted, if each time he is right in a different way.

Here lies a paradox few wish to admit. VAR was designed to reduce controversy, but in many cases it makes controversy more complex, because it turns a single decision into a chain of decisions. Previously, the crowd argued only over whether the referee blew the whistle. Now they argue over whether VAR should intervene, which aspect it should intervene in, and why it takes so long. Each new layer of decision is a new layer of doubt.

The crowd's emotion and the match's laws run on two different timescales. Emotion demands an immediate answer. Law demands an accurate one. When these two timescales collide, the person who suffers is always the referee — placed between two pressures with no right to explain. Professionalism is not when a referee blows the whistle correctly, but when he dares to blow it even as the whole stadium roars that he is wrong.

What I want to stress is this: Vietnamese football does not lack capable referees. Vietnamese football lacks a transparent system of communication between referee and crowd. In the world's leading leagues, the crowd hears the referee's own voice explaining the decision. In V.League, decisions still arrive in silence, accompanied by a big screen displaying a few lines no one can read in time. Silence does not protect the referee. Silence only leaves a gap for rumour to fill.

A system never collapses because of someone's error; it collapses because of the silence of those entrusted with the scales.

If I could propose one thing for V.League next season, I would not ask for more machines. I would ask for the full release of the audio dialogue between the on-field referee and the VAR assistant in every intervention, and for VAR to be applied evenly in every match rather than scattered across a few. Transparency does not weaken referees. Transparency strengthens them, because it turns a doubted decision into an understood one.

I have no power to sanction, but I have a duty to see what the man with the whistle does not want to see. And what I see in V.League right now is not a league short of technology. It is a league learning to trust its own process.
