Imagine the potential fall out if it ever leaked which clubs/players voted for which referees though!
Imagine Anthony Taylor wins it and it comes out that Liverpool voted for and Man City didn't. Anthony Taylor then officiates a game involving one or both of the sides and makes a controversial decision that directly impacts the result (penalty, RC etc).
There's be huge potential for claims that he was bias because X,Y & Z voted from him.
I'm not for one minute suggesting any referee would act in favour of any club based on voting as such an award but the press would have a field day!
I spend the majority of my games trying to stay out of the Am spotlight and not be the centre of attention, the last thing I'd want is a bloody presentation, trophy and speech!!
