VAR and Vietnamese Football: From Skepticism to Technological Standard

The match between Hanoi FC and SHB Da Nang in Round 12 of V.League 2026 left an unforgettable mark on my mind. In the 78th minute, the ball hit the arm of an away defender inside the penalty area, but the referee did not blow the whistle. I sat in front of the screen in Nha Trang, replaying the slow-motion footage dozens of times. The third camera angle clearly showed the extended arm, but the main angle was obscured by the player's body. That was the moment I realized: the human eye is not enough, and Vietnamese football needs a different eye. The context of this situation is not simple. V.League 2026 witnessed 214 referee errors in just the first 10 rounds, and 67 of them directly affected match results. This number is not coincidental. It reflects a referee training system that has not kept pace with the speed of the game, as players become faster and smarter at concealing fouls. I started a blog called "Referee Data" to record every wrong decision, every camera angle, every second of pressure that referees face. The article about that match attracted 50,000 reads, and more importantly, it was shared among V.League coaches – those directly affected by these decisions. The 2026 World Cup in Russia became a turning point. For the first time, VAR was applied at a major tournament, and I analyzed all 64 matches with 455 interventions. The results were astonishing: 20 decisions were overturned, and the average review time was just 70 seconds. In the final between France and Croatia, I predicted VAR would intervene at least once in the first half for a handball – and it happened in the 59th minute. My 5-part series titled "The Referee's Eye – How VAR Changed the World Cup" reached 500,000 views, and I began receiving invitations to write columns from major sports newspapers. But what I valued most was not the numbers, but how VAR changed player behavior. They became more cautious, no longer deliberately committing fouls in the box because they knew the cameras would not miss anything. In 2026, the COVID-19 pandemic offered a rare research opportunity: matches played in empty stadiums. I analyzed 112 Bundesliga matches and found something fascinating: the home-team advantage rate dropped from 17.8% to 4.2%, and the average time for referees to make decisions decreased by 1.8 seconds. The empty stadium did not ease the referee's burden; it exposed every judgment before silence. Without the roar of home fans, without crowd pressure, referees had to rely entirely on their ability to read situations. The results showed that when not influenced by the environment, they made more accurate decisions. My research passed peer review by two international experts and was published in a sports science journal. This also became the foundational data for my master's thesis in Exercise Science. The 2026 World Cup in Qatar took me to a position I never dreamed of: sitting in the VAR operation room at a major broadcaster. I witnessed 172 offside checks and noted that semi-automated technology reduced review time from 70 seconds to 25 seconds. In the quarterfinal between Argentina and the Netherlands, I predicted the referee would show at least 4 yellow cards in the final minutes due to the tense history between the two teams – the actual result was 6 yellow cards, including 2 in extra time. This prediction helped my program achieve the highest rating of the quarterfinals. But what troubled me most was the moment I looked at the screen and saw the VAR officials as tense as if they were standing in the middle of the pitch. They are not cold machines, but human beings who must make decisions in seconds, with millions of eyes watching. I never say a referee is wrong. I only say their perspective lacks sufficient light. That is exactly why I support VAR not only in V.League but at every level of Vietnamese football. But technology is only part of the story. The 2026 V.League referee error table is not a starting point; it is a mirror reflecting an entire system. If we only install cameras without improving training processes, without transparency in explaining decisions, without listening to feedback from clubs, then VAR is just an expensive useless tool. Every slow-motion replay is a surgery: cut right, cut wrong, but never cut in haste. Referees need time to assess, and VAR needs procedures to ensure consistency. I have seen decisions overturned only because of an unclear camera angle, and I have also seen correct decisions upheld after a 3-minute review. The issue is not whether VAR should exist, but how to make it a natural part of the game, without disrupting its rhythm, without creating new injustices. The 2026 World Cup gave me a question: if the human eye is not enough, why not trust the machine? And the answer I found after 5 years is: the machine is never enough if the humans behind it are not properly trained. VAR does not replace referees; it only gives them more light. But that light needs to be used correctly, with clear procedures and transparency at every step. Then VAR is not just technology, but a new standard for fairness on the pitch.
