Been talking about this a little on the other thread. I think VAR was brought in with the stated aim of overturning clear and obvious errors - Maradona's handball against England, Neuer cheating against England, or perhaps when Koeman cheated against England to randomly pick three horrendous and famous refereeing errors.
However, they seem to be using it to try and attain a perfection that can never really be achieved, and the result is that the game is being slowed down hugely for very little gain.
To me VAR should work as follows - you have people in a box watching VAR, after every decision by the ref, the players in that box have twenty seconds to press a button which says "wrong" - they only press that button if they are certain it was wrong. If a majority (three or more) of the officials press that button in the twenty seconds following then it's overruled. If, in 20 seconds, they are not sure it was wrong, then it was not a clear error and the game continues. I'm not interested in microscopic offsides invisible to the naked eye in which the player clearly didn't seek to gain an advantage by being 05mm ahead of the defender. I'm interested in the removal of embarrassing errors where ten seconds after the incident, everyone at home or in the stadium knows that the ref cocked up or the scorer was 3m was offside. Huge errors of that nature should be speedily removed. That's it, no long delays, no decisions where the ref couldn't have possibly got it right or the player clearly couldn't have done it deliberately. Just that. What we're stuck with is a fuck-up, nothing like what we were promised - it's exactly like brexit really.
