What is Video assistant referee?
'''Video assistant referee''' (VAR) is a system that helps [[referee]]s to decide better about players fouls, if a goal was valid, red card decisions, etc. in [[soccer]] matches. When the referee is going to review a play on the field at the VAR box, they outline a square with their hands, as if showing the outline of a [[TV]] screen.
