0.2 Metres and the VAR Room Lesson: When Technology Cannot Rescue Human Hesitation

In November 2026, at San Siro, Milan hosted Juventus on matchday 12 of Serie A. I sat in the VAR operations room, my eyes fixed on the monitor. In the 56th minute, Gonzalo Higuain put the ball in the net to make it 2-0. But the feed showed the Argentine striker had been offside by 0.2 metres — a distance the naked eye could never detect, but slow-motion footage never misses. I hesitated. I was afraid of being wrong. I did not recommend the referee review it. Milan lost 0-2. After the match, the referee supervisor criticised me in front of the entire team. That was the moment that shaped how I have viewed football for the past seven years. I tell this story not to justify myself. I tell it to say this: the biggest error of VAR is not in the technology, but in the psychology of the people operating it. And in any football culture — Serie A, the Premier League, or the V-League — the problem is identical. Before I blow the whistle, I review myself. Context: When technology promises more than it delivers VAR was trialled by FIFA from 2026 and officially introduced at the 2026 World Cup in Russia. The promise was simple: fewer errors, more fairness. But according to IFAB data — the body that governs the laws of the game — referees' correct-decision rate only rose from around 93% to 98-99%. Technology does not eliminate error; it narrows the gap. In a single match, that 1-2% can mean a Champions League place, a title, or a relegation-deciding goal. I sat in the VAR room long enough to understand one thing: technology only supplies data, while the decision still belongs to a human being. And a human being, even one supported by the 37 criteria I once built, can still have a shaky hand. After the Milan-Juventus match, I reviewed 47 similar incidents over the course of a month. I built a 37-point checklist to standardise decisions. From then on, I never offered a judgement without a foundation. That was how I paid for my hesitation. In Vietnam, VAR was introduced to the V-League in 2026. It is a major step forward, but it also raises a question: do we have enough resources to operate it correctly? A VAR system needs at least four wide-angle cameras, two offside cameras, a compliant operations room, and most importantly — referees properly trained in the decision-making process. What really makes a correct VAR decision? There are three layers. The first is data: offside positions measured in centimetres, the moment the ball leaves the foot, the point of contact between ball and hand. The second is the law: Law 11 on offside, Law 12 on handball, and IFAB's guidance on the threshold for clear intervention. The third — and the hardest — is match management: tempo, player emotion, and the context of the scoreline. Every judgement needs a review, including the judgement of data. I do not trust my eyes; I trust slow-motion footage. In June 2026, at the World Cup in Russia, Sky Sport Italia invited me to commentate on VAR for the France-Argentina round-of-16 match. Before kick-off, I used data from the last 14 matches in Ligue 1 and the Champions League: Kylian Mbappe's sprint speed reached 36.5 km/h, 2.8 km/h faster than the average Argentine defender. I wrote a 1,200-word analysis arguing that Argentina's defensive structure would collapse when Mbappe accelerated between the 60th and 70th minutes. The result: Mbappe won a penalty and scored twice, and France won 4-3. The piece was shared more than 5,000 times. But what I learned was not that I had been right. What I learned was this: data can predict events, but it cannot replace the referee's decision on the pitch. Mbappe did not appear out of nowhere — he was predicted by my model before the world knew his name. But the moment he went down in the box, the referee still had to blow the whistle in a split second. The view from the whistle: What the stands never see I have always stood in the position nobody notices on the pitch. From there, I see the hidden angles that players, coaches, and stands miss: the hesitation of the assistant referee before a ball near the touchline, the pause of the centre referee before making a call, and the silence in the VAR room when a slow-motion replay is rolled back again and again. Football is a game of errors, but the winner is the one who knows which error is worth making. A good referee is not one who never errs. A good referee is one who understands where he might err, and builds a process to minimise that error. That is why I spend hours analysing difficult offside calls instead of relying on instinct. This is also true of Vietnamese football. V-League referees are gradually getting used to VAR, but the biggest issue is not technical. It is psychological: do referees have the courage to overturn their own decision when the monitor shows they were wrong? Across many V-League matches in the 2026-2026 season, I observed a familiar pattern: the centre referee often hesitates to call VAR in the first 15 minutes, tends to uphold the original decision when the score is level, and only changes it when pressure from players or the stands rises. This is not unique to Vietnam — it is a problem of every league newly adopting VAR. The paradox of emotion and law Fans usually do not oppose VAR because it is wrong. They oppose it because it is slow, because it shreds emotion, because it turns a moment of euphoria into a courtroom. But if VAR were faster, would it be more accurate? Data from major leagues suggests not necessarily. An offside decision takes an average of 60-90 seconds to confirm. Cutting that to 30 seconds could significantly raise the error rate. The real issue is not speed. The real issue is consistency. The same incident, the same footage, yet two different referees can reach two different conclusions. That is VAR's blind spot: it standardises images, but not people. I witnessed Milan's collapse in the 2026 season, when Serie A returned with empty stadiums because of COVID-19. Milan went on a run of seven matches without a win. Many blamed the sale of Andre Silva to Monaco for 35 million euros. But I analysed transition data over the last 14 matches and found that Milan's defence lost up to 42% of its counter-attacking resilience without crowd noise driving the press. Milan's collapse did not begin with the pandemic; it began with the cracks that the pandemic only made visible. I wrote a 30-page report for La Gazzetta dello Sport proposing a three-phase recovery plan. It was published in full. Not because I guessed right, but because I identified the mechanism. Lessons for the future Technology does not kill football; it kills blind faith. VAR will continue to exist, and will continue to spark debate. But if football federations — including the VFF — want VAR to be truly effective, they need to invest in three things: systematic referee training, transparency in the decision-making process, and acceptance that error is part of the game. I do not trust my eyes; I trust slow-motion footage. But footage can also deceive us if we do not know what we are looking for. Football is a game of errors. And the true winner is the one who knows which error is worth making.
