Watched the game online manc and i'd have to say at the moment, despite all the English media building him up (is there a world cup coming up or something?) as having a great season, I'd say Rooney's form is more worrying than Berbatov's. Rooney's touch seems very, very heavy. he's snatching at things and making some very poor choices.
I can appreciate what you're saying about Berbatov though, just doesn't seem to be happening for him. Carrying an injury though and I do still think United are a better side with him in it. I am a fan of his, I think he's a cracking player but I do agree that patience is running out, certainly not playing like a £30m player.
Van der Sar makes a huge difference to United. Not just the fact he's a great goalkeeper, but the quickness in starting attacks and his all round excellent distribution is a massive plus over Scrabble and Foster.
