The Video Assistant Referee — universally known as VAR — was introduced into the Premier League ahead of the 2019–20 season following a trial period in other competitions. It represents the most significant change to football officiating in decades, and few innovations in the sport have generated more sustained debate.
What VAR Can Review
VAR checks four specific match-changing situations, and only four. These are defined precisely by IFAB (the International Football Association Board) and are not at the discretion of individual leagues to expand:
- Goals: VAR checks all goals for any offside in the build-up, handball by an attacker in the build-up, and any foul in the build-up that would disallow the goal.
- Penalty decisions: VAR reviews incidents inside the penalty area that may constitute a foul or handball resulting in a penalty — whether a penalty was incorrectly awarded or incorrectly denied.
- Direct red card incidents: VAR reviews decisions involving a direct red card (serious foul play, violent conduct, or denying an obvious goal-scoring opportunity). It does not review second yellow cards.
- Mistaken identity: If the referee dismisses or books the wrong player, VAR can intervene to correct the error.
What VAR Cannot Review
It is equally important to understand what falls outside VAR's scope:
- Yellow card offences (except when mistaken identity is involved)
- Second yellow cards leading to a red
- Offside situations that do not directly lead to a goal
- Throw-in direction decisions
- Whether a corner or goal kick is correct
- Time-wasting or simulation that does not result in a card decision being reviewed
How the VAR Process Works
The VAR team operates from Stockley Park in west London — a centralised hub where officials monitor all Premier League matches simultaneously using live video feeds from multiple camera angles. Each match has a dedicated VAR and an assistant VAR (AVAR).
The process begins with the on-field referee making their initial decision. The VAR team watches the relevant footage and assesses whether a “clear and obvious error” has been made. This threshold — “clear and obvious” — is the key standard for all VAR reviews outside of offside. It is designed to prevent VAR from overturning every marginal decision; only demonstrably incorrect calls should be changed.
If the VAR team identifies a potential clear and obvious error, there are two possible outcomes:
- VAR advises the referee: For offside decisions (which are binary and can be de
termined objectively) or in cases where the evidence is unambiguous, the VAR may advise the referee to change the decision without an on-field review.
On-field review (OFR): The referee is invited to review footage at the pitchside monitor. After watching the replay, the referee makes the final decision. The on-field referee's call following an OFR is final — VAR cannot overrule them a second time.
Why VAR Remains Controversial
Despite its stated purpose — eliminating clear and obvious errors — VAR has generated considerable frustration since its Premier League introduction.
The central criticism is inconsistency. Decisions that appear similar to fans watching replays at home have been treated differently in different matches, raising questions about whether the “clear and obvious” threshold is being applied consistently. The Premier League has responded by publishing regular explanations of key VAR decisions through their PGMOL (Professional Game Match Officials Limited) communications, though many fans remain unconvinced.
A second criticism relates to the atmosphere inside grounds. Goals are now routinely followed by a period of uncertainty rather than immediate celebration, as fans await confirmation that VAR has not intervened. For supporters attending matches, this delay erodes the spontaneity that has always defined live football.
A third concern is handball. The handball law — particularly as it applies to ball-to-arm incidents in the build-up to goals — has been modified several times since VAR's introduction, as the sport attempts to find a workable standard that distinguishes deliberate handball from accidental contact. This has been a source of ongoing confusion for players, managers and supporters alike.
Despite these criticisms, VAR has undeniably corrected errors that would previously have stood — goals scored from offside positions, wrongful penalty awards, and incidents of serious foul play missed by officials in real time. The debate is not so much about whether technology should assist officials, but about how that assistance should be calibrated and communicated.
