I've said it before, but although I would rather VAR didn't exist - there is a right way and a wrong way to do it.
We actually saw the right way during the 2018 World Cup.
The VAR assessor in a back room somewhere took a quick look at every major decision. Where they could, if it was marginal - they let it go. If it was questionable, they flagged it and the ref took a look.
In 62 games, there were 440 occasions where VAR reviewed decisions - but they were all quick, and didn't hold up the game significantly.
Only 19 decisions were flagged for the ref to take a second look; the ref then changed 16 of those.
In other words, less than a third of the matches were affected at all by VAR......and those that were, for the most part it was to correct a clearly wrong decision.
The wrong way to do it is the 2019-20 Premier League season. Multiple VAR pauses every game. Lack of consistency in decisions. Creating more controversy than it saves.
To take offside as an example - if offside is suspected, what the assessor should do is take a quick look (no more than 10 seconds) at a freeze frame of the incident.
If they can't tell within those 10 seconds that the decision was clearly wrong, then they should immediately stick with the decision that the officials made on the pitch (i.e. the World Cup model).
What they shouldn't do is spend the next two minutes drawing lines on the screen, to verify if a player's toenail was 5mm in front of the defender. That's both tedious, and trying to apply precision and exactness to a game that is neither precise nor exact. And it's killing football. I pray it never reaches League One.
