VAR and the Data Gap: 523 Matches I Counted to Understand a Referee's Eye

Minute 55, Kazan Stadium, 16 June 2026. Referee Andrés Cunha left the penalty area, ran to the monitor by the touchline and reviewed the incident between Josh Risdon and Antoine Griezmann. Forty seconds later he pointed to the spot. I was sitting in a Valencia radio studio, in front of a microphone, telling more than four million listeners that the ball had struck the armpit area and therefore there was no offence. I was wrong. The colleague beside me opened his file and read the clause aloud: since 2026, the boundary between the shoulder and the arm had been defined as the bottom of the armpit. The station had to issue a correction on air. In thirty years of work, that was the first time I had been contradicted directly in public.

The match finished 2-1 to France and nobody disputed the result. The question I received most often in the weeks that followed was a different one: why would a man who has lived on football law for thirty years state a clause incorrectly when it had been amended two years earlier? The answer does not lie in my memory. Football has digitised everything about players down to the centimetre, yet there is almost no standardised data system for refereeing decisions.

The law does not live in memory, it lives in data. I learned that at a considerable price, and from August 2026 I began repaying the debt in my own way.

In August 2026 I opened a spreadsheet and logged every VAR-involved decision in La Liga and the UEFA Champions League: error code, minute, distance between referee and incident, ball speed, review time and final decision. By March 2026, when the COVID-19 pandemic stopped football, my spreadsheet held 523 matches. Within that dataset, 74 per cent of contested offside decisions had an average review time of 47 seconds. I published a 48-page report on my personal blog in April 2026, including a proposal to cap each review at 30 seconds. The Valencia football federation subsequently invited me to advise on reforming the process.

At the 2026 World Cup, semi-automated offside technology arrived and cut offside decision times to a few dozen seconds. Handball did not improve. Offside is geometry, handball is intent, and no camera records intent.

According to the law reference table I maintain, IFAB's Law 12 changed three times in five years: 2026 defined the shoulder-arm boundary at the bottom of the armpit; 2026 added the criterion of the arm extending beyond the shoulder line and disallowed goals when the ball touched an attacker's hand immediately in the scoring phase; 2026 tightened the concept of the arm making the body unnaturally bigger. A 40-year-old referee officiating since 2026 has had to apply three different versions of the same law, in three different competitions, with three different interpretations handed down by governing bodies.

What makes VAR controversial is not the referee's eye, but the fact that nobody measures that eye with the same ruler. Across the 523 matches I logged, I classified decisions into three groups: clearly wrong under the clause, correct but contested at the threshold, and unclassifiable for lack of camera angles. The third group accounts for most of the loudest storms, and that is a technical problem, not a moral one.

Referees do not need protection. They need to be understood through correct numbers. When a decision in the 90th minute causes outrage, the stands shout about bias, and the statistics tables shared online usually ignore one simple variable: time. A referee has three seconds to decide a handball incident inside the box, and thirty seconds to review the same incident. Those two mental states cannot be judged by the same standard. One match is only a story. Five hundred matches are the law.

Based on my experience watching matches, games with a host club from the large-club group produced average review times eight seconds longer than the rest of the same matchday. The sample is small, the margin of error large, and I do not use it to draw a conclusion. I use it only to say that the question of crowd pressure is a legitimate research question, not a conspiracy theory to be dismissed with sarcasm.

The paradox sits in the fact that audiences demand consistency, while laws are not written to be consistent across time. IFAB amends the laws every year, usually effective from 1 June, and major competitions may apply them differently. Consistency within a season is measurable; consistency between two versions of the law is impossible. By the same logic, judging a referee on a single decision is like judging a player on his first match back from injury: the verdict comes too early, and the pressure created on that return is precisely what makes the next mistake more likely.

The 2026 World Cup will bring more technology, more cameras and more noise. What that tournament needs is not another camera angle but an open database of refereeing decisions, detailed enough that anyone can verify rather than argue. At 67, I do not need to remember everything. I need to know how to find what is correct, and I want the next generation of referees to be judged by data, not by the memory of those sitting outside the touchline.
