This isn't what VAR was brought in to check for. It was supposed to be clear and obvious errors and this is plainly not clear or obvious. Im sure we can all remember the odd, rare goal where someone was 2 yards offside and score and whilst annoying at least it was a talking point.
I cannot understand thy the PL want to rule goals out like this. It kills the game, slows it down, bores and frustrates supporters and can be used to influence games. In this case it's possible to give a goal or not give a goal.
They need to start getting a grip on this now. It's an absolute disgrace and is absolutely unjustifiable.
