The 'Clear and Obvious' Threshold: When VAR Is Designed Not to Intervene

The referee stands before the touchline monitor, one hand pressed to his earpiece, eyes locked on a slow-motion replay. Behind him, two technical areas pull taut as bowstrings. In the stands, tens of thousands of fans hold their breath, waiting for a signal: a raised hand, or a nod of release. In those ninety seconds, football stops being a game and becomes a small courtroom — where the laws are read aloud, but emotion cannot be suppressed.

I have watched moments like this for years, not to decide who is right or wrong in the manner of a supporter, but to cross-check every ruling against the written law and against a database of previous calls. The first mistake is not there to be erased, but to be compared later.

Context: A Protocol Designed to Preserve the Original Decision

VAR — the Video Assistant Referee — was formally written into the Laws of the Game by IFAB in 2026, after years of trials in national leagues and continental cups. Its core principle is not to find absolute truth, but to correct clear and obvious errors in four categories: goals, penalty kicks, direct red cards, and mistaken identity. These four categories are packaged in a famous slogan: minimum interference, maximum benefit.

The key lies in the phrase clear and obvious. IFAB does not define it with a number. There is no centimetre threshold for offside in the original law text. There is no quantification of how clear a phase of play must be. The threshold depends on the judgment of the VAR and the on-field referee — meaning, in the end, on human beings.

I once spent one hundred and twenty hours reviewing ten Bundesliga matches from the 2026-2026 season — a league that adopted the five-substitution rule during the pandemic, while the Premier League kept three. On average, each match saw three point two substitutions between the 60th and 75th minutes. That number says nothing about right or wrong, but it reveals a truth: when the law changes, the way a match is run changes with it, and new controversies appear exactly where the old law had never reached. VAR is the same. When a new protocol arrives, it does not erase controversy — it merely relocates it.

A high defensive line is a bet; I only record the moment the gambler turns over the card. VAR is a similar bet: the more offside lines are drawn to the millimetre, the more temptation there is to intervene in situations the law never permitted intervention for.

To understand why this protocol matters, one must look back at history. Before VAR, a refereeing mistake was permanent. Diego Maradona's goal against England at the 2026 World Cup — the Hand of God — could not be undone. Zinedine Zidane's red card in the 2026 World Cup final remains a recorded full stop. After VAR, the assumption is that mistakes can be corrected. But the protocol was written the opposite way: only correct when the mistake is big enough for everyone to see. This is the central paradox I want to dissect.

From the 2026-2026 season, IFAB tightened the definition of handball inside the penalty area — a change intended to reduce absurd penalties born from high-resolution frame reconstruction. But that very tightening created a new paradox: phases that the human eye cannot see are now judged very strictly. Before VAR, a penalty was only awarded when the referee saw the foul. After VAR, a penalty can be awarded when nobody saw anything at all — except a single enlarged frame.

Core Analysis: The Luis Díaz Moment and Three Layers of Error

Return to Tottenham 2-1 Liverpool on 30 September 2026. In the 34th minute, Luis Díaz ran onto a through ball from Mohamed Salah, rounded goalkeeper Guglielmo Vicario, and slotted the ball cleanly into the net. The assistant referee did not raise his flag. Referee Simon Hooper awarded the goal. Then the VAR team of Darren England and Dan Cook intervened and announced offside.

The audio released later by PGMOL revealed a chain of errors that lay not in technology, but in people. First layer: the VAR team drew the offside line on the wrong player. Instead of using Díaz as the reference point, they used a Tottenham player in the frame — an identification error, something anyone who has ever watched a replay knows is cardinal. Second layer: after drawing the line, the VAR declared check complete, while the on-field referee misunderstood that the goal had been confirmed. Hooper said thank you and allowed play to continue with the goal disallowed. Third layer: neither VAR official realised their error until the match had moved on.

These three layers are not the fault of one individual. They are the fault of a process. And for someone in my profession, that is a more important lesson than any on-field refereeing error.

The same situation, two ways of blowing the whistle — the law is never ambiguous, only the person holding the whistle is. The offside law is clear: a player is offside if any part of the body that can score is closer to the opponent's goal than both the ball and the second-last defender, excluding the hands. Nothing is vague. But applied to a complex frame with ten legs, two heads and a moving ball, ambiguity appears — and it lies not in the law, but in the angle of the person applying it.

This is why I always cross-check at least twice before every article. As an intern in 2026, I once misspelled the name of France striker Amine Gouiri as Gouini four times in the first half of the U-20 World Cup opener. My editor corrected it and gave me a stern warning. After the match, I spent two weeks reviewing every group-stage recording, memorising the exact names and shirt numbers of one hundred and twenty players. From then on, I built a private data table noting player-name transliterations to FIFA standard, and applied a rule: name, shirt number and playing position must be checked at least twice before publication.

That lesson applies directly to VAR. When the VAR team at Stockley Park drew the offside line on the wrong player, they broke exactly the rule an intern must follow: verify identity before concluding. Technology cannot save a weak process.

But fairness is required. VAR is not the sole cause of these controversies. Look at basketball — a sport I also follow closely — where personal-foul and technical-foul laws have been standardised over decades, with referees trained under a single global programme. Football, by contrast, lets each national federation interpret clear and obvious in its own way. Inconsistency between leagues is part of the problem, and it cannot be solved by adding more machinery alone.

Contrarian Angle: The Problem Is Not That VAR Is Slow, but That It Is Too Fast

Public opinion often criticises VAR for slowing the game down. But looking at the Díaz case, the problem was the opposite: VAR was too fast.

Look at the numbers. According to PGMOL's report, an average VAR check lasts around seventy seconds. In the Díaz case, the VAR team spent less than a minute. They did not verify the player's identity. They did not pause to consult a colleague. They chased the speed of the process — and speed turned into carelessness.

I believe in the naked eye, but VAR taught me that the naked eye can lie. And a process designed to protect the continuity of the match can destroy the very continuity it seeks to protect, if the people running it prioritise speed over accuracy.

There is also a psychological layer rarely discussed. The VAR is not the final decision-maker — under the protocol, the on-field referee is. But in practice, the on-field referee almost always trusts the earpiece. When the VAR says offside, the referee nods. When the VAR says check complete, the referee understands it as nothing to correct. A hierarchy on paper becomes deference in practice. And when the VAR errs, no one on the pitch is alert enough to challenge it.

This leads to a deeper paradox: VAR was created to ease the burden on the on-field referee, yet it created a new layer of intermediaries who can make mistakes without immediate scrutiny. With every wrongfully disallowed goal, the audience's trust in refereeing drops a notch — and no offside line can draw back the trust that has been lost.

Takeaway

I do not believe VAR will disappear. I believe it must learn to slow down. After the Díaz case, PGMOL changed its protocol: requiring the VAR to confirm the player's identity before drawing an offside line, and adding a cross-check step between the VAR and the assistant VAR. These are technical adjustments, not a reform of philosophy. But they show one thing: the first mistake — whether by a player, a referee, or an intern who misspells a name — is never erased. It is only archived, waiting for the day it is compared.

The question is not whether VAR should exist. It is: at what point does a process designed to protect the match become the very thing the match needs protection from?
