On Sunday the ref was 5 yards away from the handball. It happened quickly. He can whistle and award the penalty. This will of course be reviewed by Var and he could be invited to watch it on the screen as he made a mistake. This opens him up to ridicule for making a mistake.
A far easier option, no matter what he has seen, is do fuck all, give nowt and let Var make the decision. That imo, is what he did, he took the lazy, unprofessional way out.
The problem this can lead to is when it becomes a habit. Don't make big calls, let Var do it but that then brings in the Clear and Obvious rule where Var won't get involved.
The whole Var set up is wrong, it is unprofessional in the way it is operated. Different clubs have a different amount of cameras, some clubs even have blind spots. Everything about Var is unprofessional and open to abuse.
