How VAR works in football: Complete guide to Video Assistant Referee (2026)
VAR divides football fans like no other technology. Here is a clear, complete breakdown of how VAR works, what it can and cannot review, how long decisions take and what IFAB's latest rules say.
Video Assistant Referee — VAR — is the most significant change to football officiating in the sport's history. It is also the most controversial. Depending on whom you ask, it is either the saviour of correct decisions or the destroyer of football's emotional spontaneity. The truth, as usual, is more complicated. Here is everything you need to know about how VAR actually works.
What is VAR?
VAR is a system in which a team of video officials monitors a match in a dedicated review centre, watching multiple camera angles in real time. Their sole role is to assist the on-field referee with a small category of reviewable decisions by correcting clear and obvious errors.
The key phrase is "clear and obvious error." VAR is not designed to check every decision — it is designed to catch the mistakes that would significantly affect the outcome and that can be definitively resolved with video evidence.
What can VAR review?
VAR is limited to four categories of "game-changing" decisions:
1. Goals and goal infringements Every goal is automatically checked for the following: was the scorer in an offside position? Was there a foul in the build-up? Was the ball out of play? Did the ball cross the line?
2. Penalty decisions Potential penalties that the referee did not award (missed incidents), and penalties that were awarded that may have been incorrect (fouls that were not fouls, simulations, or incidents outside the area).
3. Direct red card incidents Serious foul play, violent conduct, biting, spitting or deliberate handball denying an obvious goal-scoring opportunity. Yellow cards and second bookings cannot be reviewed.
4. Mistaken identity If the referee shows a card to the wrong player.
Everything else — throw-ins, corners, free-kick positions, yellow cards, most incidents of physical contact — is outside VAR's remit. This is a frequent source of fan frustration.
How does the VAR review process work?
The process has several stages:
Phase 1: Automatic monitoring VAR officials in the review centre watch the match continuously. For every goal, they begin checking automatically. For incidents in the other three categories, they monitor and flag anything that might be a clear error.
Phase 2: VAR check The VAR team reviews the footage. If they find no clear error, the on-field decision stands and no interruption occurs. Most checks happen without the referee or players being aware.
Phase 3: VAR review If the VAR team identifies a possible clear error, they alert the referee via earpiece: "Possible penalty, check advised" or similar. The referee may then go to the pitchside monitor (the referee review area, or RRA) to watch the footage themselves, or may simply accept VAR's recommendation.
Phase 4: Decision The referee makes the final call. VAR recommends — the referee decides.
Semi-Automated Offside Technology (SAOT)
For offside decisions, elite competitions (Champions League, World Cup) now use SAOT — a separate system that tracks player positions using multiple cameras and data points. SAOT generates the offside lines automatically rather than requiring VAR officials to draw them manually, reducing decision time from several minutes to under a minute.
SAOT also eliminates the human element in line-drawing, which was a previous criticism of the manual process.
How long do VAR decisions take?
This is a significant bone of contention. Manual offside checks using the old method could take five to six minutes. SAOT has reduced this to around 30–40 seconds for standard cases.
Penalty reviews typically take 1–3 minutes. The most complex decisions — violent conduct or mistaken identity — can take longer.
IFAB and FIFA have issued guidance encouraging VAR teams to be decisive and avoid "over-reviewing," but the technology's accuracy is at odds with the desire for speed.
Why do fans find VAR frustrating?
Several specific issues drive the dissatisfaction:
Delayed celebrations: Goals are checked before fans can fully celebrate. The uncertainty destroys the spontaneous emotional response that football relies on.
Interpretive decisions: Handball and "foul or simulation" decisions involve human judgment, meaning VAR sometimes "corrects" one debatable call with another debatable call.
Inconsistency: The threshold for "clear and obvious error" varies between competitions and even between match officials within the same competition.
Communication: For most of VAR's early years, stadiums and broadcast viewers had no clear explanation of what was being reviewed or why. This has improved, but imperfect communication remains an issue.
Over-precision on offside: The 2mm-armpit offsides — technically correct but visually absurd — created enormous backlash. SAOT aims to address this by producing faster decisions, but very tight calls remain controversial regardless of accuracy.
The 2025-26 rule changes
IFAB made several important changes for 2025-26 that affect VAR:
- **Handball clarity:** A new, simplified handball definition reduces the number of reviewable handball situations. Not every arm-ball contact qualifies as handball.
- **SAOT rollout:** Semi-automated offside is being rolled out to top domestic leagues after its successful application at international level.
- **Communication standards:** Broadcasters and grounds must provide clearer explanations to fans when a VAR review is occurring and what the decision was.
- **Maximum review time:** Guidance setting softer maximum expected durations for reviews (two minutes for most cases), though this is guidance rather than a hard rule.
VAR in the Premier League vs other leagues
The Premier League's implementation of VAR has been notably more conservative than UEFA competitions. The PL does not use a pitchside monitor as frequently as other leagues, relying more on the VAR official's recommendation. This has produced inconsistency and criticism.
The Bundesliga, Serie A and Ligue 1 generally follow UEFA protocols more closely. La Liga initially resisted VAR before implementing it fully.
How to watch VAR decision graphics on TV
During a broadcast, VAR decisions are typically shown with: - A "VAR Check" graphic indicating a review is in progress - Camera replays from the angles being reviewed - If offside, calibrated lines showing body positions at the moment of the pass - A "VAR Review" graphic if the referee is being advised to check the pitchside monitor - A final decision graphic confirming the outcome
Some broadcasters provide audio from the VAR official to the referee, giving viewers unprecedented insight into the decision-making process.
Frequently Asked Questions
Can the manager request a VAR review like in American sports?** No. Football has no challenge system. Only the VAR team can initiate a review, and they do so independent of any request from team officials or players.
What happens if VAR misses something?** If VAR reviews a decision and the referee is told there is no clear error, the on-field decision stands permanently — even if subsequent angles suggest it was wrong. The system is designed to achieve finality, not perfection.
Can VAR upgrade a yellow card to a red?** VAR can recommend upgrading to red for serious foul play or violent conduct that the referee missed or undervalued at the time. It cannot change a yellow card for non-violent offences.
Is VAR used in all football leagues?** No. VAR is optional and requires significant infrastructure investment. It is used in the top divisions of most major footballing nations and in UEFA/FIFA competitions. Lower divisions and smaller leagues do not use it.
Who is in the VAR review room?** Typically: the Video Assistant Referee (a qualified FIFA referee), one or more Assistant Video Assistant Referees (AVAR), and technical operators who manage the replay systems and SAOT.
