VAR makes sense in it's essence, in it's application it's still troubled by human error, threshold checks and seemingly inconsistent as to what situations it is used in. The referees need to check the video footage at the side of the pitch, that has to be a given, also fouls need to 'make sense' again because charging down freekicks with your arm isn't a penalty yet the ball innocuously striking a hand from a shot in play is. That makes no sense. Further confusing is that the former IS a foul almost everyone else VAR is used on the continent. I'm not sure why the Premier League apply VAR the way they do, maybe some hubris about being able to do it better for 'the best league in the world' but it needs some serious working on. the referees need to take VAR more seriously too and incorporate it into their association and make it something they focus on getting right or they should just let a 3rd party review footage, flag something and then let the referee decide.
The incident yesterday with Barnes at Watford, it makes referee Tierney look particularly poor. Watford have a corner and VAR awards a penalty for an earlier foul - which always looked a penalty in my view - but it seemingly took the Burnley players to be up in arms about the injustic of it before VAR announced it is checking the incident, that can't be right if it was indeed the case. It completely undermined the credibility of the match officials because without a screen for them to check to concur, we may as well ditch in game referees and use some arena AI to halt and commence play. I still wouldn't scrap VAR but it needs some serious reforms.
