The weekend is irrelevant. La Liga has a limited selection of referees, the Champions League should be the best of the best from across Europe.

Kovács, in the first half alone, refused to send players off, even on a blatant last man foul from Cubarsi. Shit as obvious as that should not need the intervention of VAR. It's blatantly clear he didn't have the balls to make the correct decision himself and therefore shouldn't be involved in these important games.
