Simply a freak season, where everything went right for him. In that season, if I remember rightly he wasn't even playing as a (9) anyway. He just scored a lot. That is also the role of a (10) anyways. The extra goals came from the fact that he played with Berbatov a lot who also likes to drop deep. I really don't think Rooney was ever asked to play the furthest up the field. And yeah, he was far from bad last season. It's his general play that is getting worse. He seems in decline to me; peaked early. Also, having better attacking players around him still won't do anything for individual play. He's lost that edge he used to have. That doesn't make him a bad player, it just makes him more transparent, and easier to defend. Jose knows more than me though. So who knows. I really don't know how you'd re-motivate somebody who's won everything there is to win in the same league.
