VAR is most used in the area of the penalty area. The decision to blow a penalty may be maintained or canceled by the referee after reviewing the video of the situation provided by VAR.
Using Var in direct red card situation
Violent acts will be prevented by VAR. However, VAR is only applied for direct red card situations, not the second yellow card.
Using Var to identify mistakes
In fact, there are many situations on the field that the referee also makes mistakes. Specifically, in the match between Arsenal and Chelsea in 2014. Oxlade Chamberlain of Arsenal was the one who made the mistake but the referee suddenly chased Kieran Gibs, another player who also owns the same head as Chamberlain. Using VAR technology, the mistakes of the referees can be corrected. However, VAR also has certain restrictions to ensure not to interrupt the game.
Application of Var technology in situations: 11m free kick, identify errors, goals and red cards directly.
Is VAR restricted to use?
Not at all, but VAR will not be used in case the game has been continued. If VAR does not detect errors, a free kick, a throw-in is automatically continued.
Goals are not determined by the VAR in the event the offensive team commits a foul in the situation leading to the goal. In general, using VAR, the referee can cool the player even though the foul situation has happened before.
Why is FIFA using VAR at Worldcup 2018?
The world’s most powerful football authority wants to improve the accuracy of decisions on the field. “I will tell football fans that this technology has a positive impact,” FIFA Infantino President said. According to the head of FIFA, VAR has been used in about 1,000 matches with an accuracy of 93-99%.
FIFA scrutinizes all the potential that this technology can bring. Infantino also said that VAR needs to improve the pace of the game analysis and communicate to the referees.
