VAR and Refereeing in the V.League: When Technology Forces Vietnamese Football to Be Transparent

The 88th minute, the score level, the referee walking toward the monitor at the side of the pitch. In the stands, tens of thousands of fans hold their breath; in the commentary box, the man with the microphone must steady his own breathing too. In England, I lived that moment many times — once as a referee, countless times as the man who explained the laws to an audience. In a season without crowds, with only the cameras rolling, I began to hear the whisper of technology. And when that technology arrived in the V.League, it did more than change how a decision is made — it forced an entire football culture to relearn how to tell the truth.

Vietnamese football entered the VAR era later than most major competitions, but at a notable speed. Under the stewardship of the Vietnam Football Federation (VFF) and the Vietnam Professional Football joint-stock company (VPF), video-assisted refereeing trials were rolled out on a phased basis: beginning with a number of high-profile matches, then gradually extending across V.League 1. Behind each extension lie money, transmission infrastructure, cameras and human training — but above all a commitment: decisions will be re-examined through images, not just memory.

For a league where the volume of controversy after every round is far from small, this is an irreversible step. In Europe's top divisions, VAR took nearly a decade to move from trial to relative stability. The V.League has no such luxury. Pressure from media, from fans, from the clubs themselves magnifies every error under a microscope. Yet that same pressure is the engine for standardising process — something Vietnamese football has needed for a long time.

The first thing I want to say as a former man with the whistle: VAR is not a second referee. It is a tool, and a tool is only as good as the person operating it. Inside the VAR room, the video officials do not make the final call — they flag a clear and obvious error, or a serious missed incident. The on-field referee remains the decision-maker. That boundary matters, because most V.League controversies do not lie in the technology, but in how that boundary is drawn.

There are four categories in which VAR may intervene: goals, penalty kicks, direct red cards, and mistaken identity. Everything else — a foul in midfield, a wrong throw-in, a yellow card waved away — lies outside the reviewable scope. Yet those are precisely the things fans complain about most. The gap between what the stands expect and what the law actually permits is fertile ground for controversies that drag on for days.

Technically, the biggest challenge in the V.League is offside. Without semi-automated offside technology like that used in Europe's top leagues, the VAR team must draw the offside line by hand — a manual job dependent on camera angle, frame and ball placement. Half a hand can become a decision argued over for a week. The boundary of fairness does not lie in technology being perfectly accurate, but in the process being made public so that anyone can verify it. When the process is transparent, a hard decision can still be accepted; when the process is murky, even a correct decision is doubted.

Here is a point rarely mentioned: VAR's intervention threshold is clear and obvious, not right or wrong. That means a passage of play may be technically wrong, yet if it is not clear enough to overturn, the referee keeps the original call. This principle was designed to protect the flow of the game, but it is frequently misread as collusion. In many situations, people argue about a decision that the laws never allowed VAR to touch in the first place.

I recall my own lesson. In 2026, in my first stint as an on-site commentator, I mispronounced a player's name three times and drew fierce backlash. I sat up all night rewatching the tape and realised I lacked knowledge of FIFA's new offside law. I built my own 27-point checklist before every broadcast and took detailed notes on both squads for three months. I have called matches wrong, but from that I learned what fairness means. Fairness is not instinct — it is a standard built, measured and defended by process.

For V.League referees, this is even harsher. They must keep the rhythm of the game, respond to technology, and absorb pressure directly from the stands right in front of them. When a referee walks to the monitor, he is not merely facing images — he is facing his own first decision, and must admit or defend it before tens of thousands of eyes. Composure lies in accepting that you may be wrong. A head referee is not someone who never errs; what matters is what he does after he errs.

There is still a school of thought that VAR kills the emotion of football. I understand that feeling, but I believe it is misplaced. What is killed is not emotion — it is arbitrariness. What fans truly hate is not waiting two minutes to review an incident; what they hate is the sense that the result was decided by someone they cannot verify. People watch matches with their hearts; I watch through lines already drawn. But precisely because they watch with the heart, they need clearer lines.

There is a blind spot few mention. In the V.League, pressure shifts from the on-field referee to the VAR room, but transparency has not risen accordingly. Decisions are still explained too little, too late, and often only after public opinion has boiled over. When the public never hears the exchange between the referee and the VAR team, they tend to write their own story — and that story is usually worse than the truth. Technology does not create trust; it only creates evidence, and trust only arrives when the evidence is fully told.

It must be said plainly: VAR is not immune to human error. Some camera angles show nothing; some situations require technology itself to fall silent. A good referee in this era is not one who never errs, but one who clearly knows the limits of the tool in his hands. At the 2026 World Cup in Kazan, when defending champions Germany lost 0-2 to South Korea and were eliminated in the group stage, I withdrew into the technical room rather than stand amid a scrum of emotional interviews. I re-analysed fourteen counter-attacking situations from movement data and finished a 3,000-word piece in five hours. In 2026, the whole football world was turned upside down, and I learned to stand still and observe in the middle of the storm. Staying calm before a controversial decision is not avoidance — it is the condition for seeing clearly.

I believe the road for Vietnamese refereeing has been drawn — not because VAR is perfect, but because it demands something harder than technique: transparency. What comes next is not machinery, but people — commitments to publish, explain and train. Every argument in the stands and on the pitch has an answer lying in some camera angle; our job is to learn how to project that angle for everyone to see, before public opinion writes the story itself.
