VAR is now just the proxy for the way the ref was treated in the pre-VAR days. When he gives your side something it's "great ref, brilliant decision". Five minutes later when they give something against you it's "You don't know what you're doing!".
Personally I think the only real problem with VAR is how long it takes. Should be a rule that if it takes more than 30 seconds it's not obvious so move on. That's probably about the length of time we've seen for (e.g.) a goal ruled out by a late flag in non-VAR games.
Agree.
I posted ages ago it needs two tweeks - clear blue sky rule for offside (won't change anyting much but would 'feel' fairer to me) and a 20 second rule (if VAR can't be definitive in 20 seconds just go with what the ref decided).
