Infantino said no one on the FIFA Council was against the decision, and added: "We didn't take it lightly".
Federation Internationale de Football Association president Gianni Infantino commended the use of VAR at the World Cup, despite its opposition amongst many.
It has been trialled in Germany's Bundesliga and Italy's Serie A this season and some English FA and League Cup games, among others.
"We have complete faith in the head of our referee committee Pierluigi Collina and his team, extraordinary professionals who will prepare referees for the World Cup".
Infantino added that time-wastage had been discussed "passionately" but concluded: "It's not possible that in 2018 everyone in their living room knows a few seconds after the play whether a referee has made a mistake and the referee doesn't". "It has been approved and we are extremely happy with that decision".
SIALKOT: Besides the millions of insane football fans, Pakistanis will have a special reason to rejoice 2018 FIFA World Cup as Russian Ambassador Alexey Dedov has confirmed that Pakistan-made footballs to be used in the World Cup matches to be played in Russia this year.
"It can not be possible that in 2018 everybody, in the stadium or at home, knows in a few seconds if the referee has made a mistake but not the referee himself - not because he doesn't want to know about it but because we forbid him to know. We will see at the World Cup".
"I was sceptical at first, but without trying you can not know what it's worth".
Infantino said that VAR had been shown to reduce the number of refereeing mistakes in matches where it had been used.
"It will help to have a more transparent and fairer sport which is what we want because the referee has his work cut out for him already and sometimes he can make mistakes - like any human being - and if we can help him to correct some of these mistakes, let's do so".
