Minute 89, the score still 1-1, the ball spilled out of a challenge inside the box. The referee stood less than eight metres from the point of contact. He pointed to the penalty spot. The stands erupted in two opposite emotional directions: half jumped to their feet, half screamed in protest. Ninety seconds later, the big screen flashed the familiar line: “VAR Review - Handball”. I was sitting in row thirty-two of the Sir Kenny Dalglish Stand, a notebook with a worn spine in my hand, and I knew one thing for certain: whichever way the referee went, the next morning social media would split into two camps. No decision here satisfies everyone. That is the nature of the handball law — and it is also the nature of every VAR argument I have tracked for eight years.
Context: When rules collide with technology
To understand why that moment is so contentious, we need to return to IFAB’s Law 12 — the law governing fouls and misconduct. Between 2026 and 2026, IFAB amended the definition of “handball” at least four times. Each amendment forced referees to relearn the rule from scratch. The boundary between “arm” and “shoulder” was redrawn; the criterion of a “natural position” was redefined; the concept of “handball leading to a goal” was tightened and then loosened. The result is a pile of overlapping rules that even FIFA referees admit is difficult to apply consistently.
In the summer of 2026, when I was seventeen, I spent all of June and July watching all 64 World Cup matches in Russia. I downloaded raw data from FIFA and manually classified the 21 VAR interventions across the tournament. Of those, eight decisions remain controversial to this day because the “clear and obvious error” standard was applied inconsistently. Same type of contact, same camera angle — but a referee in one match called the foul and a referee in another waved it away. That Russian summer taught me one thing: VAR did not rob football of its innocence — it robbed it of the right to be wrong.
That same year, the Premier League began rolling out VAR on a large scale. I built a tracking database of every controversial refereeing decision, logging time, location, foul type and outcome. By 2026, my table had more than 1,400 rows. One striking finding: the rate of decisions overturned by VAR in the Premier League has not fallen over time — it fluctuates around 14-17% each season. The technology improves, but the number of controversies does not fall. This is an important data point that few people notice.
Analysis: The three layers of a decision
When a handball goes to VAR, there are really three layers of judgement overlapping.
The first layer is physical. Which part of the body did the ball strike? Was the arm in an abnormally extended position? How many metres separated the point of the shot from the arm? Under two metres, a ball that bounces off a thigh onto an arm is regarded as unavoidable. Beyond five metres, an arm extended along the ball’s path is regarded as deliberate. Between those two thresholds lies a grey zone every referee must fill in themselves.
The second layer is technical. Was the arm used to increase the body’s silhouette? Did the player actively adjust the position of their hand when they saw the ball coming? In a small study I ran with a group of students at the University of Liverpool, we found that referees take an average of 4.3 seconds to decide a handball in live play, but need up to 38 seconds to process the same incident on a VAR monitor. That says a great deal about a referee’s psychology when forced to slow down.
The third layer — and the one most often overlooked — is context. What minute is it? What is the score? Is this a derby or a final-day match? Does this player already have a yellow card? No law requires a referee to weigh context, but in my experience watching matches, they always do — consciously or not.
What is remarkable is that these three layers frequently contradict each other. A decision can be physically correct but technically wrong, or technically correct but out of step with context. When VAR intervenes, it almost only processes the physical layer. The other two remain beyond the reach of technology. This is exactly the “gap between two laws” I keep referring to.
VAR’s blind spot: the unmeasured variable
In 2026, when football returned after the pandemic, I spent six weeks collecting data from 45 behind-closed-doors Premier League matches and compared them with 45 pre-pandemic matches in the same season. Average yellow cards per match rose from 3.2 to 3.8 — an 18.7% increase. But the more shocking number lies elsewhere: the number of VAR interventions scarcely changed, while the number of aggressive player reactions toward referees fell sharply.
This raises a question VAR has never answered: when the stands are empty, I can hear the breathing of the match — but I also realised that crowd pressure is a constituent part of a referee’s decision. Without a crowd, decisions lighten. With a crowd, they grow heavier. VAR cannot measure this variable.
I call this VAR’s blind spot: the system cross-checks events, not context. A referee standing before 50,000 people screaming at him will decide differently from that same referee sitting in front of ten monitors. Technology does not erase the human factor — it merely moves it somewhere else.
For Vietnamese audiences following Asian competitions and World Cup qualifiers, this matters especially. The atmosphere at My Dinh Stadium with a crowd is a psychological variable no VAR system can encode. Crowd pressure can generate a different refereeing standard, and that standard decides the outcome of an entire four-year qualifying cycle.
The contrarian angle: when uniformity becomes the enemy
Fans often assume VAR was created to bring consistency. I think the opposite. The consistency VAR pursues is consistency in suppressing a referee’s reflex instinct. A referee without VAR uses experience, intuition and an understanding of the rhythm of the match. A referee with VAR is pulled out of that flow, forced to slow down, transformed into a technician re-reading a legal text.

The problem is not that VAR reduces errors. The problem is that it changes the kind of error. The old error was emotional — it belonged to a human, and fans forgave it. The new error is technical — it belongs to a system, and fans do not forgive systems. Because a system is supposed to be right.
This is the paradox I have observed across many leagues. Players can argue with a referee and turn away within seconds. But they cannot argue with a screen. It sits there, silent, cold, always insisting it is right.
From the first gap I discovered at sixteen — the Liverpool U18 versus Everton U18 match at Kirkby Academy in 2026, when striker Paul Glatzel received the ball in what looked like an offside position but had in fact committed no offence because the Everton defender had deliberately touched the ball first, exactly as Law 11 stipulates — I understood that football law is not a static system. It is a mechanism in operation, changing, bargaining with reality every single day.
I wrote a 3,000-word analysis of that incident and posted it on r/LiverpoolFC. An admin from This Is Anfield shared it, and the piece drew 5,200 reads and 180 comments. Curiosity about the mechanics of the laws became a professional habit: never issue an emotional verdict without watching the footage at least three times.
The calm direction
Interestingly, it is the referees themselves — the men thrown into the eye of the storm — who are the calmest group. I have had the chance to observe referees at grassroots and professional level, and what I noticed is a hard-to-explain instinct: they accept error as part of the job. They do not believe in artificial perfection. They believe in re-reading the situation, explaining it, and moving on.
Perhaps that is why I have always been sceptical of proposals for a “more complete VAR” or “AI replacing referees”. When a technology takes away a referee’s right to be wrong, it also takes away the fans’ right to trust. Football does not need perfect referees. Football needs referees who can be trusted.
With a major tournament season approaching, as national teams prepare for knockout football, the pressure on referees will rise exponentially. Every decision can decide an entire four-year cycle. And in those moments, the emotions of millions of people will collide directly with a line of text on a screen.
Takeaway
The coming major tournament will again push VAR into the spotlight. I am ready for a dozen more arguments. But next time you see an incident reviewed ten times on the screen, ask yourself one question: are you objecting to the decision, or objecting to the fact that you are no longer allowed to trust the person who made it?
People see a passage of play. I see a gap between two laws. And inside that gap, football is still trying to breathe.
