cleavers

Firstly they're not var screens, they are just simply "screens", used mostly for advertising and the like, and showing replays of important moments during the game (excluding var though).Also we’ve talked about atmosphere, surely the VAR screen adds to that.
Maybe ask the question differently. Why won’t 2 of the richest clubs in the world comply?
All it does for those 2 clubs is deprive their fans seeing replays of important moments, and I'm not sure it's a "rule" about having them anyway.
As I don't go to either ground, I couldn't care less, I would if it had any affect on var, but they have to have a var screen for the official, and they do, sadly it seems to be rarely used, but that's a different conversation.
