Imo VAR should only exist in a technical capacity to prepare footage to transfer onto a ref’s portable Fold 5 or something. Samsung could sponsor it even!
The decisions should all be made by the ref on pitch and this would massively improve the speed of play during VAR. There’s no reason they should have to walk off pitch.
I think it’s weird the ref has to look in the first place?
If the VAR is good enough the ruling should be final. (This way the players and stadium vibes cant influence the ref).
The fact that 2 refs can disagree means either the rules suck or the ref.
