What VAR is
The Video Assistant Referee (VAR) is a team of match officials — typically a VAR, an assistant VAR (AVAR) and an offside specialist — working from a video operations room with access to every broadcast camera angle. Their job is to assist the on-field referee for a narrow set of match-defining incidents. VAR does not officiate the game; it checks the referee's decisions.
The four reviewable categories
VAR can intervene on exactly four things: goals (and the phases leading to them), penalty decisions, direct red cards, and cases of mistaken identity. Yellow cards, second yellows and free kicks outside these categories are not reviewable. That deliberately narrow scope is meant to preserve the flow of the game.
The 'clear and obvious error' threshold
VAR is designed to correct clear and obvious errors, not to re-referee every decision. If the on-field call is defensible, VAR should not intervene. In practice this threshold has been the source of most controversy: fans expect consistency across matches, but 'clear and obvious' is a judgement call that varies between referees, competitions and even matches.
The review process
For every goal, penalty and red card, VAR silently checks the incident in the background — a 'check complete' happens without the crowd knowing. When the VAR believes there may be a clear and obvious error, they recommend the referee visit the pitchside monitor for an on-field review (OFR). The referee remains the ultimate decision-maker; VAR only advises.
Factual vs subjective decisions
Offside and ball-out-of-play are factual — the picture either shows the offence or it does not. Fouls, handballs and red cards are subjective, involving judgement about intent, force and context. This distinction matters because VAR is much better at factual calls than subjective ones, and most of the anger about VAR comes from subjective interventions rather than offside checks.
The offside factory
The most consistent VAR use is for offside in goal-scoring phases. Semi-automated offside technology, introduced at the 2022 World Cup and now used across the Champions League and several major domestic leagues, tracks 29 body points per player and delivers automated offside verdicts within about 25 seconds. It has largely ended debates about millimetre calls — even if it hasn't ended debates about whether such calls should exist.
Handball, the eternal argument
The handball law was rewritten multiple times between 2019 and 2023 to try to define 'unnatural' arm positions objectively. It has not fully worked. VAR now flags contact that was invisible in real time, and referees rule on whether the arm made the body 'unnaturally bigger'. Different competitions apply the same words differently, which is why identical incidents can produce opposite outcomes.
Impact on the flow of the game
The main criticism of VAR is not that it makes errors — the error rate is measurably lower with VAR than without — but that it interrupts the emotional flow of matches, delays celebrations and creates uncertainty about whether a goal 'counts' until 90 seconds later. IFAB's Football Video Support (FVS), a lighter-touch alternative used in lower-tier competitions, allows coaches to challenge decisions but relies on fewer camera angles and no dedicated VAR room.
What comes next
Trials of referee announcements — the referee explaining decisions to the stadium via microphone, as in rugby and the NFL — began in select competitions in 2024. Semi-automated offside is expanding. The Premier League introduced 'delay indicators' to signal to fans when VAR is checking. None of these fully resolves the debate, but the direction of travel is toward faster, more transparent decisions.
Frequently asked questions
- Can VAR review a yellow card?
- No. VAR can only intervene on goals, penalties, direct red cards and cases of mistaken identity. Yellow cards and second-yellow sending-offs are not reviewable.
- Who has the final decision, VAR or the referee?
- The on-field referee. VAR only advises; the referee can decline to review or can overrule the recommendation. In practice referees almost always accept the recommendation to visit the monitor.
- Why does VAR take so long?
- Most delays come from checking multiple phases of a goal-scoring move (offside, foul in build-up, ball out of play) and from the on-field review process where the referee walks to the pitchside monitor. Semi-automated offside has significantly reduced delays for offside checks.
