It is needed, but only in ways when there is a big mistake from the main referee,which is affecting the game, but not for reviewing if there was an offside with 0.0001 mm or to review a situation after 2 minutes from happening and in that time the other team scored a goal, but the people in the VAR room told the referee to see again the situation before the goal and then to cancel the goal of the other team and whistled other thing. That kills the game. That kills the emotion of the most popular game in the world. The VAR system should be used only for penalties, real offsides or possible red card.
