The World Cup is here and video assistant referees will be new addition at this year's event.
Video assistant referees will help referees in matches look for clear and obvious errors in four game-changing scenarios: goals, penalty decisions, red card incidents and mistaken identity.
VARs can help decide if a goal should not be awarded. They make sure no mistakes were made with either the award or non-award of a penalty kick or the sending off or not sending off a player in a red card incident. VARs can also help inform the referee which player to send off during a case of mistaken identity.
