At the 58th minute, on 16 June 2026, at Kazan Arena. Referee Andrés Cunha stood inside the penalty area, one hand pointing toward the spot, his eyes still fixed on the monitor by the touchline. Josh Risdon had lunged in with his left foot, the point of contact landing on Antoine Griezmann's right ankle. The whistle did not sound at once. The VAR team called, Cunha stepped away from the incident, reviewed the footage, then turned and pointed. The first penalty in World Cup history awarded through technology. Four years earlier, in Brazil, such a moment would have passed in silence.
I sat in front of the screen, my data sheet open, and logged that instant as a milestone. From that second on, football's question was no longer "did the referee see it," but "did the system call the law correctly." Through a referee's eye, you cheer for no one. You only find the one who is right.
Context: from a lone whistle to a multi-layered system
The 2026 World Cup was the first tournament to use VAR at scale, after IFAB approved the trials and FIFA decided to deploy it from the group stage. The mechanism rests on a single principle: a clear and obvious error. Four categories of incidents permit intervention — goals, penalties, direct red cards, and mistaken identity. Outside those four, VAR has no right to touch the game, no matter how badly the referee errs. This is the legal boundary many fans ignore when they scream for justice.
Before 2026, a decision inside the box depended on one pair of eyes and one instant. The referee ran fifteen metres from the point of contact, his angle blocked by players, and the call had to be made within two seconds. The error rate in such moments was never measured systematically, and that gap is exactly where technology stepped in. Technology did not rewrite the law. It changed who gets to name the law, and when.
The "clear and obvious" threshold drew the most criticism. That threshold is a matter of judgment, not of measurement. On the same incident, two different VAR teams can reach opposite conclusions while both believing they followed the guidance. FIFA tried to narrow the ambiguity through training camps and sample clips, but ambiguity in legal language cannot be erased by a meeting.
I spent that entire summer building a personal tracking sheet, logging every time VAR touched the game across all 64 matches. Not to blame anyone, but to answer a question the organisers never published: how accurate is this system really, and how does that accuracy shift as the pressure rises.
Core: 335 times the law was named
The results from my tracking sheet: 335 VAR interventions across the tournament, 20 overturned decisions, and 10 penalties originating directly from the technology. 335 VAR interventions, 335 times the law was named on the pitch.
The most striking point lies elsewhere. VAR's correction accuracy in the group stage reached only 68.4%, but rose to 91.2% in the knockout rounds. The system touched the game less as the tournament deepened, yet each touch was more precise. Those who look only at the number of interventions will miss this paradox.
Three reasons explain the gap between 68.4% and 91.2%. In the group stage, VAR teams handled a larger volume of incidents with the same number of people, while referees were not yet used to the rhythm of cooperation. The intervention standard tightened round by round, as FIFA adjusted internal guidance after each technical meeting. And most importantly, knockout matches contain fewer borderline incidents, meaning that when VAR calls, the error is usually clear enough to call.
Sorting by category reveals a different picture. Offside is the cleanest group, because it is geometric and can be measured with a line. Direct red cards are the hardest, because they demand an assessment of intensity and intent, things no ruler can capture. Penalties sit in the middle, hinging on whether the point of contact fell inside the box — a question the goal-line technology family can now answer.
Referee selection for the knockout rounds also contributed to the accuracy gap. At that stage, FIFA favoured referees experienced in officiating elite matches and already familiar with VAR from domestic leagues. A referee who had worked with the technology in the Bundesliga or Serie A cooperated with the VAR team more smoothly than a colleague encountering it for the first time. Experience does not appear on the score sheet, but it shows in every call.
Twenty overturned decisions out of 335 interventions is a notable ratio. Most VAR calls do not aim to overturn a decision, but to confirm that the original call was right. Fans remember the overturns; the confirmations fade into oblivion. That is why the felt experience of VAR is always more negative than the data.
The final on 15 July 2026 is the fullest example. Ivan Perišić handled the ball inside the box, referee Néstor Pitana initially waved play on, then reversed after review. It was a valid penalty under the law, but it opened a debate over how the distance between arm and body should be measured. Technology answered the question "was there a handball," but not the question "does that handball deserve a penalty." Those two questions belong to two different layers of the law.
My tracking experience shows something the statistics sheet does not display: most of a VAR team's time is not spent finding errors, but deciding whether an error is clear enough to call. Fans often misread this point. They think VAR is an error-detection machine. In reality, VAR is a decision-making process, and the intervention threshold is the soul of that process.
Contrarian angle: emotion is not evidence
When a decision is overturned, the stands respond with volume, not argument. The crowd believes any call favouring their team is right and any call against it is wrong. That is instinct, and instinct has no place in a referee's report.
The counterintuitive point is this: consistency matters more than accuracy in any single moment. A referee who awards a penalty for a light handball in the 10th minute and ignores an identical incident in the 80th has created a greater injustice than any isolated error. The law does not require a referee to be right on every ball. It requires him to apply the same measure to every team, in every minute.
This is also the trap that data people like me fall into: believing numbers stand alone and are right. The 91.2% rate in the knockouts does not mean VAR is flawless. It only means that within that sample, under that pressure, with that guidance, the system performed better. Strip the number from contest density and scoreline pressure, and it becomes a meaningless fragment.
There is a technical issue few mention: the frozen frame. When VAR pauses a moment, it strips away everything that happened before and after. A tackle that looks brutal in a still image may be the product of a run-up and a loss of balance in real motion. The law is written for a game that flows continuously, yet it is judged through disconnected slices.
We must also speak of the grey zone. Within Article 12, a challenge can be just strong enough to count as violent and just light enough to be merely careless. No line divides those two zones. The lawmakers knew this, so they left room for judgment — and judgment is what technology cannot replace, only support. That is the referee's eye, something no camera can buy.
Takeaway: as technology matures, people must mature with it
After 2026, VAR travelled on to later World Cups, to domestic leagues, and to Vietnam. V-League began introducing the technology from the 2026 season, with early matches still full of hesitation. The lesson from 335 interventions is not about buying more cameras. It is about building a consistent intervention standard, training referees to understand the calling threshold, and teaching fans that fairness is not something you can shout into existence.
After the 2026 World Cup, IFAB tightened the handball definition and then loosened it again, because decisions like Perišić's showed the law needed to be clearer. Each time the law changes, VAR teams must learn from scratch, and accuracy goes through another adjustment cycle.
Technology will keep advancing: semi-automated offside, smart balls, three-dimensional lines. Each new layer pushes the hard question back toward people. Machines determine the point of contact; humans decide what that point of contact means. That boundary will remain, however high the camera resolution climbs.
If one day V-League can publish its own correction accuracy, transparently, round by round, then Vietnamese football will truly enter the era of the law being named. Until then, every controversial decision remains a test — not for the technology, but for those sitting behind the screen.
