VAR in V.League: When a Decision Takes Three Seconds, But Three Years of Data to Earn It

In the 2026 season, VAR entered V.League 1 for the first time. I was in Valencia, sitting in front of a screen with a stopwatch in hand. A ball in the box, the referee running to the touchline, the monitor lighting up. From the whistle to the hand pointing at the penalty spot: one minute and forty-two seconds. The stands did not boo. They went quiet. And in that silence I understood that the biggest question about VAR in Vietnam is not “right or wrong,” but “how long it takes to know.” Law does not live in memory; it lives in data. And the data on VAR in V.League, at the time I compiled it, is still too thin to be called law. VAR reached Southeast Asia by a very different path from Europe. In Vietnam, the Vietnam Football Federation (VFF) and the Vietnam Professional Football Joint Stock Company (VPF) had to solve three problems at once. The first is people. Under FIFA standards, a match using VAR needs at least three certified referees: a main referee, a VAR assistant, and a second VAR assistant. The number of Vietnamese referees certified to operate VAR is small, and each can only work a limited number of matches per round. This is a hard constraint that money cannot erase in a single season. The second is infrastructure. VAR needs many camera angles, especially for offside. In top European leagues, that number is usually twelve to fifteen angles per match. In V.League’s early phase, the number was significantly lower, and that directly affects the accuracy of offside calls — the hardest family of decisions in modern football. The third, and the most underrated, is habit. Vietnamese players grew up in a football world where the referee was the only judge, with no monitor and no correction. When VAR arrived, it did not only change how referees decide. It changed how players argue, how fans wait, and how the media ask questions. From the 2026 season onward, I have logged every VAR incident in V.League 1 that I could follow through match footage. My method mirrors the personal project I ran in 2026: coding each incident by error type — offside, handball, foul in the box, red card — along with the timing and the gap between the original incident and the whistle. The first thing the data shows: average review time in V.League is higher than what I have measured in European leagues. Most of the delay does not come from referees hesitating. It comes from a lack of clear angles. A handball with only two angles, one of them blocked by a player, forces the referee to watch again and again. Each rewatch costs ten to fifteen seconds, and the match cools with every one of them. The second: the most disputed category is not offside, but handball. The reason is not the law. The law has been clear since the 2026 amendment, which extended the hand boundary down to the armpit. The reason is that handball depends on an extremely short moment, and in V.League the number of cameras fast enough to capture that moment remains limited. The third, and the point I want to stress most: consistency between referees. In my data, the same type of incident — the ball touching a hand in an extended position, making the body unnaturally bigger — is sometimes penalized and sometimes not, depending on the referee and the moment in the match. This is not evidence of bias. It is evidence of the absence of a shared reference standard written into a document. A referee cannot be consistent with himself if he has no sample incidents to compare against. One match is only a story. Five hundred matches are the law. Placed in a regional context, Thailand and Malaysia also introduced VAR in the same period, with similar difficulties in referee numbers and camera counts. What differs in V.League is the speed of improvement. After only a few rounds, review time for clear incidents fell, thanks to assigning dedicated VAR referees rather than rotating them match by match. That is the right step, and it comes from process, not luck. There is a widespread belief that VAR was created to eliminate controversy. That is false. VAR does not eliminate controversy — it relocates it. Before, people argued about the referee. Now, they argue about the monitor. The question shifts from “was he right?” to “did he see enough angles?” And when the question shifts, the pressure shifts with it. In V.League, that pressure is especially visible in matches involving big clubs. The stands are fuller, the media coverage is denser, and the VAR referee sits in a closed room but still feels the weight. A referee treating big clubs and small clubs differently is not necessarily a conspiracy. It can be a response to real pressure. And precisely for that reason, referees do not need to be protected. They need to be understood through correct data. One thing about the limits of the data must also be stated. I can only log what match footage shows. Incidents that are never replayed, angles that are never broadcast, the audio exchanges between the main referee and the VAR referee — all of that lies beyond reach. So every conclusion from this project should be read as a sample, not as a verdict. I once got one sentence wrong and lost an entire reputation. If only I had known this back then. At 67, I do not need to remember everything. I need to know how to find what is right. With VAR in V.League, what is right is not about buying more cameras. It is about writing a handbook of sample incidents, updated with each season’s law amendments, so that every referee shares the same reference root. Then a three-second decision will no longer need three years of data to justify itself.
