VAR in V-League: When Technology Meets Vietnamese Football Culture

Minute 71, Hang Day Stadium, the whistle of referee Nguyen Dinh Thai rang out amid fierce protests from Hanoi FC players. Van Quyet's goal was disallowed after 4 minutes 32 seconds of waiting — a figure far exceeding the 2-minute standard FIFA recommends for standard review situations. I sat in the VAR room at the operations center, watching the response time of the Vietnamese VAR team displayed on the screen: 272 seconds, 2.4 times the average in K League 1 in the 2026 season. That moment encapsulated the entire story of VAR implementation in Vietnam's top league — a story not about technology, but about people and operating systems. Since VAR was officially introduced to V-League from round 6 of the 2026-2026 season, there have been 214 review situations across 182 matches as of the end of the 2026-2026 season. This figure equates to 1.18 situations per match — significantly lower than K League 1's 1.62 and the Premier League's 1.71 in the same period. But what's notable is not the frequency, but the rate of overturned decisions: 41.6% in V-League compared to 28.3% in K League 1 and 24.7% in the Premier League. In other words, Vietnamese referees are wrong nearly half the time when asked to review — and that raises big questions about their initial decision-making process. I spent 6 years as a VAR assistant in Korea, 3 of them directly operating the system in Incheon. When VFF invited me to consult on VAR referee training procedures in 2026, I brought a 200-page notebook of K League review situations — and quickly realized that V-League's problem is not a lack of technology. The camera system, reconstruction software, automatic offside lines — all met FIFA standards. The problem lies in this: Vietnamese referees are trained to trust their eyes, not to trust the process. Look at the data I collected from 214 review situations. The average time for a review in V-League is 3 minutes 47 seconds — compared to 1 minute 58 seconds in K League 1. More notably, in 89 overturned decisions, 67 cases (75.3%) involved the main referee standing in a good observation position with a clear view of the situation. So why did they still make the wrong initial decision? The answer lies in a concept I call "home pressure" — a phenomenon not written in the rules, but carrying real legal weight. In a study I conducted for the AFC referees committee, I found that Vietnamese referees tend to make decisions favoring the home team 23% more often than Korean referees in 50-50 situations before VAR intervention. This is not due to a lack of integrity — but due to psychological pressure from the stands, from club management, and from a football culture where silence after a controversial decision is seen as failure. Vietnamese referees are taught to "manage the game" — a concept I have never heard in FIFA training courses. Every VAR error is a crack in the mirror reflecting the laws. But the biggest crack in V-League is not in the final decision — it's in the process leading to that decision. I analyzed 47 situations where the VAR team did not call the main referee to review, but were later criticized by public opinion. In 39 cases (83%), the VAR team had sufficient evidence to call — but they chose not to because they "feared disrupting the flow of the match." This is a systemic error, not an individual one. When I asked Vietnamese VAR referees for their reasons, the most common answer was: "If I call incorrectly, I'll be rated poorly in the end-of-season assessment." They are afraid of being punished for doing the right thing, rather than afraid of doing wrong. The trap of 2026 is not in the hand, but in the belief in a definition that does not exist. In V-League, a similar trap lies in the belief that VAR will automatically fix every mistake. But VAR is not an automatic machine — it is a process operated by humans, with limitations of perception, time, and pressure. When I reviewed the VAR room audio recording of the match between Viettel and HAGL in round 12 of the 2026-2026 season, I heard the VAR assistant say to the main referee: "Brother, look again carefully, the crowd is protesting." The crowd is not written in the rules, but they are present in the decision. My data shows another worrying trend: review time in V-League increases progressively each round. Rounds 6-10, average 2 minutes 54 seconds. Rounds 11-15, 3 minutes 28 seconds. Rounds 16-20, 4 minutes 12 seconds. By rounds 21-26, this figure reached 4 minutes 51 seconds. This shows that referees are increasingly dependent on VAR — not because they want to be more accurate, but because they are afraid of making decisions without technological backing. They are transferring responsibility to machines, instead of using machines to support their own judgment. In contrast, in K League 1, I witnessed a completely different approach. Korean referees are trained to view VAR as a confirmation tool, not a lifeline. They are encouraged to maintain their original decision if the situation is not clearly a "clear and obvious error" — a standard I noticed Vietnamese referees understand very differently. In training sessions at VFF, I saw Vietnamese referees often ask: "If this situation is 50-50, should I call VAR?" The correct answer under FIFA rules is: "No, because there is no clear error." But the answer they often receive from supervisors is: "It depends on the situation, but if you let it go, the crowd will boo." We seek on the pitch not justice, but an excuse to stop arguing. In V-League, that excuse is often found in the VAR room — but it never truly stops the argument, only delays it. I have followed Vietnamese football forums throughout the 2026-2026 season and noticed a repeating pattern: each controversial decision creates a wave of criticism lasting 3-5 days, then subsides until the next decision. There is no substantive discussion about improving the process — only alternating anger and cooling off. The natural position — a concept I use to describe the fair coordinates that the laws expect — in V-League is often distorted by the home-field factor. My data shows: in matches with home crowds above 15,000, the rate of decisions favoring the home team before VAR was 58.2%. When VAR intervened, this figure dropped to 41.7%. But the notable point is: VAR cannot fix what it is not called to. In 27 situations I identified as "clear errors" but the VAR team did not call, 19 cases (70.4%) occurred at stadiums with large crowds. Pressure from the stands is neutralizing the very technology created to counter that pressure. A wrong decision does not ruin a match; the silence after it is what damages trust. I witnessed this in V-League during the 2026-2026 season, when the VFF Referees Committee refused to release VAR room audio recordings after a controversial incident in the match between CAHN and Binh Duong. Instead of calming tensions, that silence created a wave of suspicion that spread wider. Clubs began questioning the transparency of the entire system, not just that decision. I sent a 12-page petition to VFF proposing full release of audio recordings, but the response I received was: "We will consider." Eight months have passed, and I still have not received an answer. Meanwhile, in Korea, the K League has released all VAR room audio recordings to the public since the 2026 season. What was the result? Official complaints dropped by 34%, and fan trust in referees increased by 27% in surveys. Transparency does not diminish referee authority — it increases it. But in Vietnam, management culture still prioritizes protecting image over building trust. This is a systemic difference, not a personal issue of any official. VAR was born from the fear of mistakes, but it nurtures the fear of delayed truth. In V-League, I see that fear turning into something more dangerous: acceptance. Clubs have grown accustomed to controversial decisions, players have grown accustomed to waiting 4-5 minutes for each review, and fans have grown accustomed to never receiving a full explanation. This familiarity is the greatest enemy of progress. When I asked a V-League club director whether he would like to see improvement in the VAR process, he replied: "Yes, but if it works as it does now, we can accept it too." That acceptance is a deeper crack than any referee error. Because it prevents all reform efforts. I proposed 5 specific changes to VFF: (1) cap review time at 2 minutes maximum, (2) release VAR room audio recordings, (3) retrain all referees on the "clear and obvious error" standard, (4) establish an independent committee to evaluate controversial decisions, and (5) implement a public scoring system for referees. As of writing, only proposal 2 is being "considered" — and I am not optimistic about the outcome. But I am not writing this article to criticize. I am writing because I believe Vietnamese football deserves better. I have watched V-League matches since I was a boy in Hanoi, and I have witnessed the remarkable growth of the league — from empty stadiums to packed stands of 20,000. That journey cannot be ruined by opaque decisions. VAR technology is a gift — but only if we know how to use it properly. Based on my experience following matches in both Korea and Vietnam, I can state one thing: the difference between an effective VAR system and a controversial one lies not in technology, but in operating culture. Korea took 3 years to build that culture, starting with releasing audio recordings. Vietnam can do it faster — if there is the will. The question is: do we have the courage to look into the mirror and accept what it reflects? Every VAR error is a crack in the mirror reflecting the laws. But a mirror can be repaired. It only needs people brave enough to admit it is broken — and patient enough to piece it back together. I believe Vietnamese football has such people. I just hope they will emerge before the cracks become unbridgeable gaps.
