Videos could decide the result of the competition this year. And it will almost certainly prove controversial
The World Cup will put the greatest footballing nations on Earth to the test. But there is another trial happening, perhaps just as important and even more controversial: that of VAR, or the video assistant referee.
The technology is being used at the World Cup for the first ever time, and has the potential to fundamentally change games. It could decide the future of the tournament, by reversing some of the most important refereeing decisions in the game.
Proponents claim that VAR will ensure that decisions are fair and that the best team wins. But even those supporters admit that the technology is still at a very early stage – with supporters and referees still apparently confused about how it should actually be used.
Despite that complexity, the technology is fundamentally incredibly simple: it is an extra referee who watches the game and advises officials on decisions. In practise, though, it might be very complicated indeed.
There are 13 officials who can be chosen as the video assistant referee. They will all sit in a special hub in Moscow – no matter where the game is happening – and they will do so wearing their full kit, as if they were ready to jump onto the pitch at any time. Of those, one will be chosen for each game, and they will have a team of three assistants.
In there, they will receive a stream from inside the stadium, which is made up of the view from a whole host of cameras – including slow motion ones – which the referees can flick between.
The VAR will watch the whole of each game. If they see something wrong, they can flag it to the referee; if the referee thinks something is wrong, he can get in touch with the VAR. Either way, the VAR is only advisory. Any decision ultimately rests with the referee, even if he has advised the opposite way by the VAR.

A welcome development

If it was used during champions league final, they would have seen how Sergio Ramos fulaniherdsmened salah's hand. Nice one from FIFA
