Just thought I'd better check in after all the shameless self-promotion links I keep seeing around the place!
As a starting point i'd like to mention Nemanja Vidic. He's managed to damage not just one but three knee ligaments and is out for the season and possibly longer. I know he's a dirty red and I'm not but I reckon he's the second best defender in the EPL (after Kompany obviously) and I wouldn't wish such a career threatening injury on anyone. I hope he gets back to his best as soon as possible.
Very decent comment kb. Misguided about Kompany, naturally, although he's very good.
Our best player ought to be Rooney, flashes at the weekend but he needs more service and better quality around him. On recent form, I'd have to say Nani.
