WHAT CAN THE VAR RULE ON?
The VAR can rule on four different categories of "key match incidents"…
Goals
Did the ball cross the line, was there a foul or an offside missed in the build-up to the goal or did the ball go out of play in the build-up?
Penalty incidents
Was a foul committed inside or outside the penalty area, has a penalty been missed or has one been wrongly awarded?
Direct red cards
Was a potential send-off missed or was a red card wrongly issued?
Mistaken identity
Was a yellow or red card awarded to the wrong player?
