Where do you start with VAR? Seriously: which is the biggest problem with the video assistant referee system that has brought the Premier League to the brink of meltdown this season?
Is it the repeated disallowing of goals because of assorted body parts straying millimetres offside? Is it the endless wait for key decisions, such as penalty calls, to be resolved? Is it the absolute failure of a single match referee this season to walk a few yards to the side of the pitch to watch a replay of a contentious incident before deciding himself whether he was right or wrong in the first place?
