I think the danger is if the the premier league gets VAR then how long before the rest of the leagues demand it to keep the football ethos of "uniform, equal rules from top to grass roots" and the cost in money that would bring. It seemed to have a big impact on games in the WC though, maybe not for the better and became bigger than the games themselves sometimes and wasted a lot of time too, disrupting momentum etc.

Think even VAR got it wrong once or twice in as well and it could serve to undermine referees decision making and their confidence to make a decision - they could end up using it for everything in the end, even previously simple decisions.

Used to be in favour of it but now not sure.
