Nah, there are more accurate decisions coming out of VAR than not. Obviously the fewer wrong decisions get highlighted. The Liverpool one being, rightly, the worst one. Though ironically, if there was no VAR, the linesman there wrongly had his flag up and the goal still would not have stood.
For the factual ones like ball over the goal line, or out of play, excellent system. For offside, should be the same with clear lines (and technology is getting better) ...but the human communication process there ( as per Liverpool) needs to be drastically streamlined and improved. Not rocket science to get simple confirmation protocols in place, like Rugby and Cricket.
Of course it's the VAR subjective decisions which are the most problematic. Was it a foul or not ? Was he interfering with play ? Was it a red or yellow card? Was it handball ? ( though for god's sake tidy the law up).
Subjective decisions will always be argued over, whether VAR or not. By Clubs, by pundits, or in the pub. And by ex refs, where we've seen them disagree after a game.
VAR will not be binned. It's here to stay. But has to be an ongoing improvement process , and the Liverpool game is one where a lesson for clear simple communication can now be hardwired into the system.
