The good news is that VAR is still in its trial stage. As far as the Video Assistant Referee goes, that is where the good news ends.
The system is not working. It is flawed at almost every level. If plans to use it at the World Cup go ahead, we won't be coming home until August.
A personal view is that football never needed VAR. I always maintained that goal line technology – which has worked flawlessly – was enough. Subjective decisions such as fouls should remain exactly that and, as such, be left in the hands of the match officials.
