I'm guessing this was after the last Vardy dive which the ref seemed to point to the spot for, and then was overridden by the offside. As it wasn't a goal, I don't think VAR can intervene for the offside call even if it was wrong.
Anyway, was there any difference between what they did with the ref compared to when ManU, ManC, Liverpool or Arsenal confront the ref when a decision goes against them?
