VAR is far from perfect bit a major portion of he blame for it causing problems must go to the seriously incompetent referees, who despite seeing the video footage DO NOT objectively apply the laws of the game and still try to apply their own interpretation if the rules. The most blatant example I can think of is the 2017 Confederations Cup final - Chile vs Germany. Jara blatantly elbows Werner in the face and it is clearly intentional. Should’ve been a straight red after seeing the replay but the incompetent referee is too weak to apply the laws of the game objectively and instead shows a yellow. After that the next 30 minutes Chile feel like they can get away with all sorts of fouls, diving, etc. by the 90th minute the game has already blown out of hand with a brawl between Kimmich and Bravo. Moral of the story. In the above instance VAR was not at fault but the guy applying was a useless ****. The system will get better with more udae but it is the inept referees who are the problem and they need to be taken care of first. As for why I personally favour VAR? As long as VAR can help in the following instances: 1. Not allowing Offside Goals 2. Blatant dives to earn penalties or get opposition players sent off (Neymar might quit football if this comes go fruition) 3. Correct red cards for obvious red card challenges (the Jara instance above or when Alli tried to break De bruyne’s Leg) 4. Booking the correct player. Sometimes the incompetent referees goof up and give yellow cards to the wrong player. 5. Correcting Corners and throw in decisions. While it may look as if an incorrectly given corner or throw in might not be a big deal. These throw ins and corners can lead to goals. Case in point: In the 2010 WC final the Spanish goal kick from which Iniesta scored the winner should have been a Dutch corner. Howard Webb and his stupid linesmen incorrectly gave Spain the goal kick and the rest is history. Those are the five things I would love the VAR to fix.
