He cleaned the place out of everyone who could have helped him. It was a hard job, but that team, albeit a bit old, had won the league by a fair margin. His arrogance collapsed it. He is a man who I will always despise for the contempt he showed this club. He's a fraud from the past IMO and Everton will find that out.
After your post I read on expecting to see Laurie McBellendery mentioned. And I wasn't disappointed Howard the duck Wilkinson was a dour bastad anarl.
I'm no fan of his but taking the United job was the definition of a poisoned chalice, if he brought his own team in that's understandable and a standard thing to do. Fraud is probably a bit strong considering how long he's managed in the prem.
