so, a referee on the field made the correct decision, to be over-ruled by a referee with the benefit of replays, to then be shown to be correct by another bunch of referees watching the same replays. top work by all.

i don't recall, did green run over to look at the screen or just award the penalty based on the word of the VAR?

if he did, then he's just as culpable as the VAR. if he didn't, then he's just as culpable as the VAR for not telling him to bugger off.
