There are two things about this argument I don't like. One is the accusation that people who are against VAR are against all kinds of progress in football. I'm not. The rules evolve, and if they improve things, like the change to the offside rule, three points for a win, the play-offs or the back-pass rule, then I'm all for it.
The second thing, and the more insidious one, I think, is to do with the fact that this rule change, unlike the ones above, is one that can't be rolled out throughout the game. It reinforces the idea that above a certain level, football is important simply because there's more money riding on it. And by implication, lower levels of football (like ours) are not important. That's got nothing to do with fairness. It's all about conserving value for investors.
And quite apart from that, there's the practical side. Not only does it drag out beyond all reason (as at Mainz v Freiburg), but you could replay the run-up to any goal or any other incident and if you look carefully enough, you'll find some infringement by either side. Footballers are always at it.
It's no fairer than any spontaneous decision by a referee, and actively makes the sport as a spectacle worse..
