Three Seasons of VAR in V.League: The Equipment Is There, the People Are Not

Same matchday, same league. At one ground, the VAR team sits in a cabin, three camera angles rebuild a challenge inside the penalty area, the referee runs to the monitor, watches, overturns his decision. A few hundred kilometres away, a near-identical challenge happens, and the call is made in two seconds, with the naked eye, with nothing to review. Two matches, two standards. The final table does not distinguish between the club that dropped points because it had no cameras and the club that dropped points because it had cameras and still got the call wrong.

That is the most awkward paradox of Vietnam's top professional league after three seasons of refereeing technology, and it does not sit in the hardware.

VAR arrived in V.League 1 in the 2026 season, after a FIFA-supported referee training programme and infrastructure investment by the Vietnam Football Federation and the Vietnam Professional Football Joint Stock Company. In the first season, the number of grounds equipped for the system could be counted on one hand, so every matchday contained two kinds of fixture: matches with VAR, and matches without. A point won at a ground with no cabin therefore did not carry the same legal value as a point won at a ground with one.

At the same time, the organisers had to bring in foreign referees for a number of fixtures deemed sensitive, usually in the closing weeks when the title race and the relegation battle converge. That is crisis management. It settles one specific match and leaves a long-term question about the standing of the domestic officiating corps.

On personnel, the number of Vietnamese referees on FIFA's annual list can be counted on one hand. Names such as Nguyễn Xuân Son, Nguyễn Tiến Linh or Nguyễn Quang Hải appear in every bulletin after every round; the man with the whistle appears in no bulletin at all, except when he is being criticised. Based on my experience following matches in both V.League and the European leagues, the gap between those two groups is not one of ability. It is one of professional structure.

The first thing to separate out is the technical layer. VAR does not create pictures; it consumes pictures supplied by the host broadcaster. A match with fewer camera angles gives the VAR team fewer options, and the same incident in two different matches can produce two different conclusions simply because one side lacked the angle. VAR quality in V.League is therefore not a constant. It is a variable that depends on the television schedule.

But the hardware has never been the real bottleneck. Under IFAB rules, VAR intervenes in four categories — goals, penalty decisions, direct red cards and mistaken identity — and only when there is a clear and obvious error. The "clear and obvious" threshold is not measured with a technical ruler. It is a professional agreement among people trained on the same curriculum. When that agreement is thin, every VAR intervention generates more argument rather than less. People watch football with their hearts; I watch it through pre-drawn lines; the point is that those lines have to be drawn identically at every ground.

One detail tends to be overlooked: the viewer hears the whistle but never hears the reason. In many leagues, after reviewing the monitor, the referee announces the decision over the stadium public-address system, and the television audience hears the full explanation. Vietnam has not done this systematically. Every argument in the stands and on the pitch has an answer sitting in some camera angle — but if nobody translates that angle into a spoken explanation, the supporter is left only with the sense of having been robbed of something he believes is his.

Behind both of those layers sits the decisive one: professional structure. Most V.League referees do not officiate full time. They have other jobs, classes, office hours, and they take charge of matches at weekends. A man who spends forty hours a week on his primary career and a few hours preparing for a professional fixture cannot be judged by the same yardstick as a Premier League official with a full-time contract, his own analysis team and a weekly review session. I have refereed matches I got wrong, and it is from those that I understood what fairness means: fairness is not instinct, it is a standard that is built, measured and protected with salaries and with time.

The familiar reaction after a controversial matchday comes in three demands: install more cameras, import more foreign referees, punish harder. In the short term, all three can make things worse.

More cameras increase the number of VAR interventions. If the "clear and obvious" threshold is not shared, each new angle becomes a new argument for the aggrieved side. Importing foreign referees creates two standards inside one league: one for the big fixtures, one for the rest. Domestic officials lose authority in front of the players, and capability is not transferred, because a foreign referee who handles two matches and flies home leaves no curriculum behind.

Harsher punishment is dangerous in a different way. When errors are penalised with fines and with lost appointments, the natural human response is to avoid decisions. Referees will wait for VAR, push responsibility up to the cabin, and the match loses its rhythm. The IFAB guidance is explicit: technology must support the decision, not replace it. A referee is not a man who never errs; what matters is what he does after he errs.

The measurement worth tracking in V.League over the next three seasons is not how many grounds have a VAR cabin, but how many referees are on full-time contracts. When a Vietnamese referee can make a living from the whistle, has someone analysing video for him every week, and has a public briefing on the difficult incidents after every round, the arguments will remain — football never runs out of arguments — but they will shift from "how did this referee call it" to "how should this law be read". That is the kind of argument a mature football nation needs.
