The 2019/20 Premier League season was the first to feature the Video Assistant Referee (VAR) after the clubs voted unanimously in November 2018 to introduce the system.
All 380 Premier League fixtures in a season will have a VAR, who is constantly monitoring the match but will be used only for "clear and obvious errors" or "serious missed incidents" in four match-changing situations:
Direct red card incidents
The final decision will always be taken by the on-field referee.
VAR will not achieve 100 per cent accuracy, but will positively influence decision-making and lead to more correct, and fairer, judgments.
In the Premier League, there will be a high bar for VAR intervention on subjective decisions to maintain the pace and intensity of the matches.
Factual decisions, such as offside or if a foul was committed inside or outside the penalty area, will not be subject to the "clear and obvious error" test.
