Vietnamese Football and VAR: When Referees Must Relearn to Trust Data
Core answer: VAR đã được đưa vào V.League nhằm giảm sai sót trọng tài, nhưng hiệu quả phụ thuộc vào hạ tầng và chất lượng đào tạo trọng tài. Công nghệ chỉ thu hẹp vùng mù, không thay thế phán đoán của con người. Key facts: - VAR không làm tăng thời gian bù giờ đáng kể: trung bình chỉ thêm khoảng hai phút rưỡi mỗi trận. - Hiệu quả VAR phụ thuộc vào số camera, đường truyền và phòng điều khiển đạt chuẩn. - Lỗi nhận thức của trọng tài không thể sửa bằng công nghệ, chỉ có thể sửa bằng đào tạo. - Minh bạch quy trình ra quyết định là công cụ rẻ nhất để hàn gắn niềm tin khán giả.

In the 88th minute at Hang Day Stadium, a collision inside the penalty area brought the whole crowd to its feet. The referee shook his head and waved play on. Thirty seconds later, his earpiece buzzed. He raised his arm, ran outside the box, and the entire stadium held its breath. I was in row twelve of stand B that afternoon, notebook open, pencil resting on the first line. Across many years of tracking refereeing decisions in England, I learned one thing: the moment most worth recording is not when the referee blows his whistle, but when he hesitates.

That afternoon I logged seven controversial situations. Not one of them was technically wrong. Yet on five occasions the crowd reacted as if a goal had just been stolen from them. That was the moment I understood: the problem with refereeing in Vietnam no longer lies in the eye. It has become a problem of trust.
To understand why trust is so fragile, we must place V.League's VAR in its proper historical flow. Vietnamese football did not lag far behind the world in ideas, but it lagged a great deal in infrastructure. A VAR system is not merely a few cameras. It is a long chain: enough camera angles, a stable transmission line, a control room that meets standards, and above all, a corps of referees retrained from scratch.
When the Premier League introduced VAR in the 2026/2026 season, I spent an entire season measuring the duration of every review. The numbers surprised me: average stoppage time per match rose by only about two and a half minutes. The fans' greatest fear — that technology would kill the rhythm of the game — turned out to be an inflated prejudice. But that lesson only holds when the infrastructure is good enough. In a league where the number of VAR-compliant stadiums can be counted on one hand, every appearance of technology is another break in the match.
That is the first paradox of Vietnamese football. People crave fairness, but they are not yet ready to pay for it with continuity.
Here I want to separate two kinds of error that every refereeing debate conflates: technical error and cognitive error. Technical error is when a referee stands in the wrong position, has his view blocked by a player, or reacts too slowly. This kind can be measured, corrected, and VAR was created to handle it. Cognitive error is different. It is when a referee sees the incident correctly but interprets it in a way the law does not permit — or conversely, the law permits it but his instinct tells him otherwise. VAR cannot fix the second kind. The camera finds the error, but only a human finds the cause.
This leads to a consequence few are willing to face squarely: when VAR is introduced into a league whose refereeing foundation is uneven, it does not narrow the gap. It magnifies the gap. Good referees will use technology to reinforce their authority. Weak referees will use it as a crutch, and every time that crutch breaks, trust drops another notch.

I once sat in a VAR control room in England and watched a team of referees take nearly four minutes just to draw an offside line. Those four minutes did not come from slow technology. They were slow because the people did not dare to decide. And that is precisely the disease Vietnamese football risks repeating: a shortage of people willing to take responsibility before the machines, not a shortage of machines. The best referee is the one nobody mentions after the match.
On the numbers, there is one indicator I always track when judging the health of a refereeing ecosystem: the rate of decisions overturned after review. In Europe's top leagues this figure tends to sit low, meaning on-field referees were right in the majority of cases. In leagues newly adopting VAR, the rate is usually much higher in the early phase, then falls as referees learn to position themselves correctly before the incident happens.
In other words, VAR is only truly effective when it changes the behaviour of referees on the pitch, not when it merely corrects them after the fact. A referee who learns this will no longer need VAR to appear too often. And when VAR appears rarely, the match keeps its rhythm and the stands keep their emotion.
But there is another dimension Vietnamese football administrators often overlook: opportunity cost. Every dong poured into a fully compliant VAR system is a dong not poured into training young referees, improving pitch surfaces, or building a transparent disciplinary process. I am not saying VAR is wrong. I am saying the order of priorities is what deserves debate. Technology is the tip. People are the root.
Vietnamese football is at an interesting stage. The national team has made its mark on the continental stage, youth academies are beginning to produce players capable of playing abroad, and the V.League increasingly draws the attention of regional media. But that growth places new pressure on referees. As player quality rises and the pace of matches increases, every refereeing mistake becomes more costly. A missed call in a lower division may be no more than a sigh. A missed call in a title-deciding match can overturn an entire season.
It is precisely here that the refereeing story intersects with the business story. Clubs invest billions of dong in players, in facilities, in media. But investment in referees is almost never mentioned. That is a systemic imbalance. People are willing to pay a high price for a striker who scores twenty goals a season, yet reluctant to spend a fraction of that on training officials good enough to handle those matches. The most valuable contract is usually the one that is never announced.
I remember a conversation with a former referee in England. He told me something I have carried through my whole career: the crowd does not remember my name, and that is the greatest compliment they can give me. In Vietnam, the opposite is happening. Referees' names appear in the papers more often than players' names in the big matches. That is the sign of a system in trouble, because a referee only becomes the main character when the match is no longer the players'.
Neighbouring leagues such as the Thai League or the Malaysia Super League are wrestling with the same problem. The difference lies in how fast organisers make decisions. Where organisers dare to publish the audio between the on-field referee and the VAR team, fan trust rises markedly. Transparency, it turns out, is the cheapest and most effective tool for repairing trust. No wide-angle cameras, no high-speed transmission required. Just the courage to let the crowd see how a decision is made. A referee's power does not come from the whistle, but from the ability to read the situation.
Here I must say something many will not like. I was once a VAR sceptic, and that is why I understand those who hate it. I understand the feeling of standing in the stands, watching your team score, then seeing a screen display a cold line announcing that the goal does not exist. That feeling does not belong to reason; it belongs to someone who has just been robbed of a moment of happiness.
But emotion cannot be the measure of justice. If emotion decides, every stand will have its own law, and football will become a war of noise. When data enters the dressing room, emotion must leave through the window. I do not call that coldness. I call it the condition for the game to survive.
The biggest blind spot of Vietnamese fans, and perhaps of those who run Vietnamese football, is believing that technology can replace judgement. It cannot. Technology only narrows the blind zone. It does not erase it. And when a football nation places too much hope in a tool, every time that tool fails, it loses more than a correct decision. It loses the last of its trust.
What I want to stress is that emotion still has its place, but in the right chapter. Emotion should not sit at the decision table. It should sit in the stands, where it belongs. A referee who lets emotion lead is a referee who has lost before the match begins. A football nation that lets emotion lead is a football nation that will argue forever about things that cannot be proven.
If I were seated at the table of those who plan Vietnamese football, I would not ask when VAR will cover the whole V.League. I would ask a different question: how many Vietnamese referees can stand firm before a crowd of ten thousand without anyone prompting them through an earpiece? The answer to that question is the true measure of a refereeing ecosystem. As for VAR, in the end, it is only a mirror. It does not make people more beautiful. It only makes them see themselves more clearly.
