Shelvey should not have been sent off. I think any fair minded neutral would agree, even if a few biased Blues can't.
It's the Man Utd factor as far as I'm concerned, and the fact that they keep getting these wacky decisions from refs smacks of dirty dealings. It's the main reason I've totally gone off them recently, especially Ferguson, who when Jamie 'Arse licker' Redknapp said Ferguson was full of class, nearly made me choke. The guy is the worst loser I've seen, and totally lacks class.
