Oddly, I do think their nagging works - Alex Ferguson was the master of getting into a referee's head and getting decisions that other teams only dream of. Jose Mourinho has tried it but doesn't seem as good.

The frustration's an interesting one - I remember this Rooney goal against Newcastle and before Rooney's shot, he's running alongside the referee complaining to him, really angry and then gets on with his job -

I wish I knew the answer to offside and VAR, every time they change the rule it becomes more confusing. We've got idiots deciding what the rules should be that less competent idiots need to implement. We need fewer idiots 😂
