my only thinking is that VAR and the ref are talking to each other and VAR saying did the ref see the incident and if so did he think it was a accident, that is why the ref didn't go to look at it, but even so it was a disgraceful decision.It's a real shame that nobody comes out and explains the decisions because I'd like to understand why the ref wasn't instructed to go and look at the studs in Gio's face situatin. The VAR guy should explain the thinking behind the process, might make it easier to cope with.
