The Video Assistant Referee system is set to be used at this year's World Cup in Russia after it was approved by football's rule-making body IFAB on Saturday. And FIFA president Gianni Infantino is confident it will have a positive effect.

According to IFAB protocols, VAR should only be used in four key cases: goals, penalties, direct red cards, and mistaken identity. Infantino said the final decision on using the system at the World Cup whihc begins June 14th will be taken at a meeting of the FIFA Council in Bogota later in March. The implementation of the VAR system has been one of Infantino's main projects since he was elected in February 2016. He has long said World Cup referees must get high-tech help to review key decisions at the 64-game tournament.
