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

The first whistle was blown by the camera, and I heard the whole world holding its breath. Thong Nhat Stadium, 74th minute, the score was 1-1. The match between TP.HCM and Hanoi FC in Round 12 of V-League 2026-2026 was entering its most tense phase. The ball was lifted into the penalty area, the home team's center-back jumped to contest with the away team's striker. Both fell together. The referee, Nguyen Dinh Thai, stood less than 10 meters away, his view obscured by another defender. He didn't blow the whistle. But then his hand touched his earpiece. The whole stadium held its breath. Players from both teams stood still. Stand A, where about 2,000 Hanoi fans were gathered, began to roar, while Stand B was eerily silent. I was standing in the technical area, less than 5 meters from the touchline, and I saw what the main screen didn't capture: the home team's center-back had pulled the away striker's shirt before the ball arrived, a detail lasting less than 0.3 seconds. Two minutes later, the referee ran to the screen, reviewed it, and pointed to the penalty spot. VAR had spoken. But the story didn't end with that penalty. That was one of the defining moments of how I've viewed Vietnamese football for the past 5 years — not from the perspective of a fan, but from the perspective of someone who has held the whistle, who has stood in the technical area, and who has witnessed how technology changes — or doesn't change — how we feel about fairness. The V-League 2026-2026 season marked an important milestone: for the first time, VAR was applied uniformly across all matches in the second phase of the league. This decision came after years of delays, with many reasons given: cost, infrastructure, and skepticism about whether Vietnamese referees were competent enough to operate this technology. According to statistics from VPF, in the 78 matches with VAR in the second phase of the 2026-2026 season, there were 47 instances where the referee was invited to review (on-field review). Of those, 23 decisions were changed: 12 penalties awarded, 9 red cards upgraded, and 2 goals disallowed. These numbers show that VAR is not just a technical tool — it's a mirror reflecting errors that the naked eye cannot catch. But there's another number I care about more: 47 on-field reviews, but only 3 times did the referee maintain their original decision after review. The decision reversal rate was 87%. I see what no one else sees, and I have to live with it. Let me tell you about a specific night — the 2026 National Cup semifinal between Steel Xanh Nam Dinh and Becamex Binh Duong. In the 89th minute, the score was 2-2, the ball hit the away team's defender's hand in the penalty area. The referee didn't blow the whistle. VAR intervened. When the referee ran to the screen, I saw something strange: instead of reviewing the entire situation, he only watched 2 camera angles, one of which was obscured by another player's back. He maintained his decision not to award a penalty. After the match, I reviewed all the footage from 12 different camera angles. The ball clearly hit the hand, and the defender's arm was extended unnaturally. But the referee only watched 2 angles. Why? Because that's all the VAR room provided him. This is the biggest blind spot of VAR in Vietnam: it's not the technology, but how we use the technology. FIFA requires a minimum of 8 camera angles for each VAR situation, but in the V-League, many matches only have 4-5 cameras, and there aren't always dedicated cameras for offside detection or goal-line technology. Five thousand members, one old screen, and belief divided into five thousand pieces. I founded the group "Saigon VAR Society – Reviewing Wrongful Decisions in V-League" in April 2026, during the COVID-19 period when global football was suspended. Initially, it was just a place for me and a few friends to review controversial situations together. After three months, the group reached 5,000 members. Today, that number is 47,000. What I've learned from this community isn't the ability to analyze the laws, but how fans process injustice. When a controversial decision is made, I don't need to read the comments to know what people think. I just look at the poll: "Penalty" or "No penalty". The ratio usually leans toward the team the viewer supports, regardless of how clear the video evidence is. This leads me to an important realization: VAR doesn't just change how referees work; it changes how fans consume football. Before VAR, when a controversial decision was made, the debate ended after 5 minutes. Now, with the ability to review every frame, every angle, the debate can last for weeks. And that creates a new problem: emotional fatigue. In a survey I conducted with 1,200 members of the group in March 2026, 68% of respondents said they felt "unfair" when their team was adversely affected by a VAR decision, even when they admitted the decision was correct according to the laws. 42% said they had argued with friends or family over VAR decisions. And 17% admitted they had stopped watching live football because they felt "too tired" of waiting for decisions. These numbers don't reflect VAR's failure; they reflect a deeper reality: Vietnamese fans, like fans worldwide, don't just seek fairness — they seek a sense of belonging. And when VAR makes a decision that goes against that sense of belonging, it creates a crack in trust. That semifinal night, I betrayed my own beliefs to embrace my heart. In July 2026, I was 20 years old, and the group had grown to 12,000 members. The Euro 2026 semifinal between England and Denmark, 104th minute, Raheem Sterling fell in the penalty area after a collision with Joachim Andersen. I reviewed the footage, saw it was just a light touch, and wrote an article concluding "insufficient evidence for a penalty". But just 20 minutes later, hundreds of opposing comments flooded in. I panicked and changed it to "could be a penalty". When UEFA confirmed the decision was correct, some members mocked me: "Thought you were the VAR eye, turns out you're just a trend follower". That was the biggest shock of my student years. But it also taught me the most important lesson about judgment: never let crowd pressure change what your eyes have seen. From then on, I split my articles into two separate sections: the "Law Rules" section based on FIFA regulations, and the "Fan Sentiment" section acknowledging social media reactions. I committed to never changing my stance just because of community pressure. And that commitment helped the group grow from 12,000 to 47,000 members in three years — because fans, even when they disagree with me, know they can trust my consistency. Now, let me take you through a detailed analysis of how VAR actually works in the V-League, and what we can learn from our own mistakes. According to VPF's report published in May 2026, the estimated cost of operating VAR for one V-League season is approximately 40 billion VND. This figure includes equipment costs, referee training, VAR room operations, and system maintenance. In the context where V-League's broadcast revenue is only around 100 billion VND per season, investing 40 billion in VAR is a bold decision — and a controversial one. But the problem isn't the cost. The problem is the efficiency of use. My analysis of 78 VAR matches in the second phase of the 2026-2026 season reveals a concerning pattern: the average time for each on-field review in the V-League is 2 minutes 47 seconds, 47 seconds higher than the Premier League average (2 minutes 00 seconds). This isn't because Vietnamese referees are slow, but because they lack experience in communicating with the VAR room. I've observed an interesting phenomenon: in the V-League, referees tend to run to the screen to review more often than necessary. Of the 47 on-field reviews, 12 (25.5%) were situations where the video evidence was so clear that the referee only needed to listen to the VAR room's advice and make a decision without running to the screen. In the Premier League, this rate is only 15%. Why do Vietnamese referees run to the screen more often? I believe the answer lies in culture. In an environment where referees are frequently criticized, suspected, and even threatened, running to the screen to review is a way for referees to "prove" that they've thoroughly examined the situation. It's a self-protective action, not a technical decision. This leads to an unintended consequence: matches are interrupted more often, the pace slows down, and the emotions of players and spectators are affected. In a league where fan passion is an important part of its identity, slowing down the game for reasons that aren't truly necessary is a problem that needs serious consideration. But there's a deeper issue I want to address: inconsistency in the application of the laws. Consider two similar situations. The first: the match between Cong An Hanoi and Viettel FC (Round 20, May 2026). In the 67th minute, the ball hit the CAHN defender's hand in the penalty area while he was jumping to contest. The referee didn't blow the whistle, and VAR didn't intervene. The second: the match between Hai Phong and Thanh Hoa (Round 22, June 2026). Almost the same situation, the ball hit the Thanh Hoa defender's hand while jumping to contest. This time, VAR intervened, the referee reviewed, and awarded a penalty. Two nearly identical situations, but different outcomes. Why? Because the "clear and obvious error" criterion — the standard FIFA uses to determine when VAR should intervene — is itself an ambiguous provision. This is the subjective judgment space I mentioned from the beginning. VAR doesn't eliminate subjectivity — it just moves subjectivity from the main referee to the referee in the VAR room. And when two different referees look at the same situation, they can make two different decisions, even when both follow proper procedure. In a study I conducted with 15 V-League referees (with their consent and anonymized identities), I gave them 10 controversial situations from the 2026-2026 season and asked them to make decisions. The result: only 3/10 situations had unanimous agreement. In the remaining 7 situations, the referees split into two camps, with ratios ranging from 60-40 to 80-20. This doesn't mean Vietnamese referees lack competence. It means that football laws — no matter how detailed they're written — still contain gaps that only humans can fill with their judgment. And that judgment, even when supported by technology, remains a human act. The referee blows the whistle, but the fans are the ones who score the final judgment. Let me tell you about another night — December 1, 2026, World Cup Qatar. The match between Japan and Spain. In the 51st minute, Ao Tanaka scored a controversial goal because the ball seemed to have gone out of play. I opened frame-cutting software, measured the ball's position based on the goal line, and wrote my article "The Ball Was Still In: Evidence from 0.04 Seconds" at 3 AM. A major fanpage shared it, and the article gained 12,000 interactions in 6 hours. The community called me "Saigon's VAR Eye". But there's something I didn't share in that article: I rewatched the footage at least 20 times before writing. And in those 20 times, there were 3 times I thought the ball had gone out. I had to stop, take a deep breath, and ask myself: why do I see two different results from the same footage? The answer lies in how the brain processes visual information. When we watch a controversial situation, the brain doesn't just process images — it also processes expectations, beliefs, and emotions. If I want the ball to have gone out, I'll see it gone out. If I want the ball to be still in, I'll see it still in. This isn't dishonesty — this is how the brain works. This explains why fans of two different teams can watch the same VAR situation and reach completely opposite conclusions. Not because one side is ignorant, but because both sides are seeing the world through the lens of their own beliefs. So, the question is: how can we build a fairer VAR system, not just in the V-League but worldwide? I don't have a perfect answer. But I have some proposals based on 5 years of observation and analysis. First, we need more transparency in the process. FIFA has experimented with broadcasting the live conversation between the main referee and the VAR room in some trial competitions. The results show that this transparency significantly reduces fan skepticism. In the V-League, we should consider adopting a similar model — at least for important matches. Second, we need to invest in referee training not just technically, but psychologically. A VAR referee doesn't just need to know the laws and how to use technology — they need to know how to manage pressure, how to handle uncertainty, and how to communicate effectively with the main referee. Third, we need to reconsider the "clear and obvious" criterion. Perhaps it's time to accept that some situations don't have a right or wrong answer — only different perspectives. And in those situations, the on-field referee's decision should stand, regardless of what the VAR room thinks. Finally, we need to acknowledge that VAR isn't a perfect solution — it's just a tool. And like any tool, its value depends on how we use it. Over the past 5 years, I've witnessed VAR change Vietnamese football in ways I couldn't have imagined when I was 17, staying up late to watch the 2026 World Cup and writing my first VAR analysis. That article only got 40 views. My friends criticized me for "writing like a textbook". But it laid the foundation for my journey — a journey that taught me that judgment isn't just a professional skill, but a moral responsibility. The referee blows the whistle, but the fans are the ones who score the final judgment. And that score isn't measured by the percentage of correct decisions — it's measured by the level of trust we give each other. When I look back on these 5 years, I realize that the story of VAR in Vietnam isn't a story about technology. It's a story about trust — about how we build, lose, and rebuild trust in those who stand up to judge on our behalf. And perhaps, that's also the story of Vietnamese football in particular, and world football in general. A story that never ends, because each season brings new situations, new controversies, and new opportunities for us to learn how to trust each other. That semifinal night, I betrayed my own beliefs to embrace my heart. But since then, I've learned that heart and reason don't have to be in opposition. They just need a space to coexist — a space where we can see both, and choose to act based on both. That's the space I want to create in every article I write. And that's the space I believe VAR — if used correctly — can create for Vietnamese football. The first whistle was blown by the camera, and I heard the whole world holding its breath. But when the whistle ends, the world keeps turning. And we — those who love football — continue to debate, continue to hope, and continue to believe that one day, fairness will prevail. Perhaps that's utopian. But perhaps, that very utopianism is what makes football the greatest sport in the world.
