I remember a ref saying, might have been Phil dose, that a red card is a red card no matter no is refereeing, no matter the angle etc.
VAR is showing how poor some referees are at making crucial game changing decisions!
I don't think you are listening to what is being said. VAR is NOT about getting the correct decision, it is about correcting clear and obvious errors. The VAR might well watch a replay where the referee has given a caution and think he would have given a red, but that isn't the basis for him to recommend a review. He has to be 100% sure that the referee was absolutely wrong, that it was a clanger, put it which ever way you like, but the number of VAR recommendations should be very low. It is designed for game changing decisions such as Thierry Henry's handball against Ireland, not routine penalty or red card decisions. It should only be used for the type of decisions where 100 referees all watch it and go "whoah, he's dropped a right clanger there".
