VAR in V-League 1: The Rulebook Is Ready, the Operators Are Not

Based on my experience following matches, one moment keeps repeating in V-League 1 across the past two seasons. The referee stands at the centre circle, hand on his earpiece, then walks toward the monitor by the touchline. Twenty-two players stop. The stands fall silent for about forty seconds, then erupt in two opposite directions, both aimed at the same man. Nobody in the stadium sees the frame he is looking at. Nobody hears the exchange between him and the VAR assistant. Two minutes later, the outcome is announced with a pointed finger.

That is where almost every VAR controversy in Vietnam over the past three seasons begins: the problem lies less in the technology than in the fact that the technology is operated inside a process nobody is allowed to see.

VAR first appeared in V-League 1 in the 2026 season, deployed across selected rounds and expanded gradually rather than covering the full calendar. The Vietnam Professional Football Joint Stock Company (VPF) has repeatedly published an expansion roadmap aimed at covering every match in the top division. What is rarely discussed is the cost structure behind each game: a control room, three to four cameras calibrated to IFAB equipment standards, a stable data link, and at least two certified operators. Remove any link in that chain and VAR either does not run, or runs in a state of risk.

Money, however, is only the first layer. The second is people, and this is where the law begins to bend.

IFAB states in Law 5 and in the VAR protocol that the referee may only change a decision when an error is judged "clear and obvious", or when a serious incident has been missed. The word "clear" is not a technical parameter. It is a human judgement. In leagues with years of practice, that word is handled through standardisation: every round, the referees' committee builds clips of model situations, cross-checks the decisions already taken, and agrees an intervention threshold for the next round. Where that habit has not formed, each referee sets his own threshold, and that threshold shifts depending on whether he is in the middle or sitting in the VAR room that day.

Three bottlenecks are holding VAR in V-League behind the rest of the region. The first is staffing. The pool of referees certified to operate VAR at international level remains thin, forcing the same group to rotate between two roles within a single season. The consequence is a consensus effect: a referee is unlikely to overturn a decision made by the man who worked beside him a round earlier, because both sit in a small group judged by the same evaluation system.

The second is process. The IFAB protocol requires the referee to review the incident himself at the pitchside review area in most cases, with the exception of objective matters such as offside or player identification. From my own observation, several V-League matches have resolved controversies through earpiece discussion alone, with no monitor. In legal terms, that approach is only permitted inside a very narrow set of exceptions. In practical terms, it erases the only thing spectators can still see: the act of deliberation. Tight offside calls, the zone where attackers such as Nguyen Tien Linh and Nguyen Xuan Son operate most often, happen to fall into the category of objective incidents most easily pushed into that closed conversation.

The third is transparency. Since 2026 the Premier League has run a programme releasing audio of exchanges between referees and the VAR room, led by former referee Howard Webb, in which contentious incidents are dissected publicly round by round. Ligue 1, where I live and follow the game, has also begun trialling similar forms of disclosure. Vietnam has no mechanism at league level, not even in the form of a summary report. The result is that the entire burden of explanation is pushed into the post-match press conference, where the answers are always shorter than the questions.

One thing needs stating clearly before going further: supporter emotion is valid data, not noise to be filtered out. When ten thousand people rise to their feet at a single incident, that is a signal about the consistency of a decision, not a ballot. But that signal is being routed in the wrong direction. It lands on one individual referee, while what needs fixing sits three layers above: too few people, too little standardisation, too little disclosure.

VAR is not wrong. The people operating VAR are, after all, only people. And an operator with no process, no shared threshold and nobody checking his work cannot be measured by the same yardstick as a system that has run for ten years. A disallowed penalty can be fixed; a gap in the laws cannot.

I read the match report before I read the news, because a match report does not lie. But a match report only has value if it exists and if everyone is allowed to read it. In V-League, the VAR report remains an internal document.

Based on what has been verified, a provisional conclusion: the widest gap in Vietnamese VAR is not in the number of cameras or the speed of the data link, but in the fact that the system does not yet force itself to explain. Three things can be done now without touching the laws. Publish a VAR report summary within 24 hours of every match. Expand the pool of certified referees enough to separate the referee and the VAR assistant in the same round. And issue a mandatory process checklist, requiring referees to record the reason for intervening or not intervening on every incident inside the penalty area.

A 38-point checklist will not save a season, but it will save the reputation of the man holding the whistle. That sounds small next to a championship. It only sounds small until the team that loses on the final matchday is yours.

The offside line has never been straight; it is only today that I can see it bend. The job of a professional football nation is not to make the line straight, but to build enough measuring tools for supporters to see the same curve the officials do.
