Var is not the problem, the problem is it's being used by human officials, who may be incompetent or inconsistent or both. That is exactly the same problem we had before Var. Even if it allows a small increase in correct decisions it is worth it. Some rules should be re worded to make some decisions more clear cut and minimise the possibility of human failings. The introduction of goal line cameras allowed a much improved judgement of whether a ball went completely over the goal line despite the usual whinging about how it would ruin the game. When was the last time you saw a 5 minute wait for a decision.
