I can't stand VAR and would jump for joy if the FA got rid of it next season. But I think a lot of people blaming VAR for Coventry's goal being chalked off need to think about the same scenario happening in a world where VAR was never invented.
Think of the following scenario: O'Hare plays the pass to Wright, who looks marginally offside in the build-up, so the linesman raises his flag and the chance never even gets created - Torp never puts the ball in the net. In the aftermath, the cameras run it back, the TV companies draw a line up to Wan Bissaka's feet, and establish that Wright was "just about level" and therefore onside.
After the match you'd get people desperately clamouring for VAR, saying we need technology to help referees make tight decisions, that bad refereeing is killing the sport and that people will simply stop watching if refereeing standards don't improve.
In the end, as much as I hate it, I don't think VAR is the problem with Coventry's goal - people just seem to react very fucking badly to losing these days and will always point at VAR as the villain.
Another example is Nottm Forest who were laughing and chuckling when a bad refereeing decision meant they got promoted a few years ago, but are now sending official statements claiming the FA are conspiring against them.
Football fans need to do a lot of thinking about what they actually dislike about Coventry's goal being disallowed - if the exact same thing had happened to United we'd all be laughing our heads off and there would be no VAR debate currently happening on this forum.
