Video Assistant Referee (VAR) in Association Football

What VAR covers and how it is organised

VAR operation focuses on four main categories of incidents: goals and offences leading to goals, penalty decisions, direct red card incidents, and cases of mistaken identity. A team of video match officials monitor live feeds from multiple camera angles in a remote operations room and communicate with the match referee through headset. When they identify a potential clear and obvious error, they either recommend an on-field review or, in some situations, the referee accepts the VAR's on-screen information without leaving the field.

Typical review process

1. VAR checks all relevant camera feeds in real time and flags incidents that meet review criteria.
2. VAR communicates the finding to the on-field referee and suggests either a review on the field or a clearance.
3. If an on-field review is suggested, the referee travels to the pitch-side monitor to examine the footage, or asks the VAR to convey the images and angles.
4. After viewing, the referee confirms, overturns or modifies the original decision; the VAR documents the process.

History and regulatory adoption

VAR was trialled at professional competitions in the 2010s and saw its first high-profile use during the 2016 FIFA Club World Cup. It was introduced at international tournaments soon after, including the 2017 FIFA Confederations Cup, and made its World Cup debut in 2018. In March 2018 the International Football Association Board (IFAB) formally incorporated VAR protocols into the Laws of the Game, establishing standardized guidance for competitions that wish to use the system.

Advantages, limitations and common debates

Advocates highlight VAR's ability to correct match-changing errors, improve outcomes on offsides, fouls, and violent conduct, and increase perceived fairness. Critics point to interruptions to play, subjective interpretation of incidents (especially handball and fouls), the time taken for reviews, and the impact on the spontaneous celebrations of goals. Leagues and governing bodies continue to refine protocols to balance accuracy with match rhythm.

Practical notes and distinctions

• Not every stoppage is reviewable: VAR intervenes only for clear and obvious errors in the four defined categories.
• Final authority remains the on-field referee; VAR provides information and advice but cannot substitute for the referee's judgement unless protocol allows.
• Implementation differs by competition: camera coverage, number of VAR officials and communication systems vary between leagues and tournaments.
