It is known that thanks to VAR technology, linesmen are allowed not to raise the offside flag at the 2018 World Cup.
This information was personally announced by the President of the FIFA Referee Committee and former famous referee pierluigi collina.
Accordingly, for unclear offside situations, the linesman is recommended to limit playing the flag because it can interrupt the match situation. After that, VAR will do that instead, accurately determining whether the situation is offside or not.
This is to make the next match possible as a promising attack situation or a scoring opportunity.
If in the past, when the referee raised the flag, the main referee blew the whistle and thought that the attack would end. Therefore, if the linesman does not play the situation continuously, after the end of the situation, he can review the situation to determine whether it is right or wrong and whether to recognize it if there is a goal or not.
Another interesting piece of information was revealed that video referees will wear an access page for referees even though they are in their private rooms. These referees also sweat a lot due to stress, so they cannot let them dress like office workers.
This is the first time the World Cup has applied video referee assist technology to identify controversial situations on the field, such as offside situations, scoring goals, making mistakes in the penalty area or fouls leading to red cards, yellow cards...
Even after each half, VAR reviews the controversial situations and the referee can completely punish the players even if they are in the break room in the middle or after the match.
