The rules, they don’t understand the rules. All this place ever has is “wah wah they are applying the laws of the game and not just making random decisions to please me.”
My issue is that it is incredibly hard to apply the rules of football in any other way than in 'real time'.
The keeper-off-the-line thing, the goals ruled out for offside, the handballs etc... are all correct decisions and fine. Any issues you have are with the rules of the game.
My issue is more with the unfair application of VAR. Yesterday in the Chelsea/Liverpool game, in the last 10 minutes Abraham went through and was offside but the linesman kept the flag down - in the end, the attack fizzled out but Chelsea retained possession in the final third. Without VAR, Liverpool would have had possession. Instead, despite being offside, Chelsea retained possession in the final third.
Football is a fluid game, a throw-in can lead directly to a goal, but VAR never looks at incorrect calls on which side receives the throw-in. It's all a bit miso-mash.
VAR isn't going anywhere, but I think it should be reserved for genuine 'clear and obvious' errors (i.e. probably getting involved less than once a game).
