Thanks for the info guys. I was only born 24 hours ago so I wasn't aware of any of this.
Wiley isn't fit to be a referee, in fact I can't think of any current referees who are fit to officiate Premier League games. Something seriously seriously needs done about it. It's happening every single game now. Vieira should have been off and the goal should have stood.
I will watch the Vieira incident with interest as to how or what the F.A. will do about it.
