‘What is VAR – and what does it stand for?
The Video Assistant Referee system, known as VAR, is football’s first use of video technology to reach more correct decisions. The system was trialled in the FA and Carabao Cups last season, as well as the German and Italian leagues.
The system has already been used in the World Cup group stage to correct and clarify decisions, including Diego Costa’s first goal against Portugal, France’s penalty against Australia as well as Sweden’s penalty against South Korea.
Is it being used at the World Cup?
Yes, following the unanimous approval of the International Football Association Board in Zurich in March, who voted to introduce the system permanently. This is the first World Cup using video replays, although goal line technology was successfully employed in Brazil four years ago.
