I don't agree. I believe he is a good, and generally very productive player - but I think he would seem better if the game was read and not watched. By this, I mean he gets goals and assists and all that, but very often, if you actually watch the football match, he doesn't look anything special at all when he has the ball. If you could somehow watch a clip of every single thing they have done this season apart from their goals and assists - van Persie would still look like a much better footballer than Rooney I think.
That's my view anyway. Of course, goals is the name of the game, and to that end Rooney is crucial, and I'm not even implying he's a Hernandez, who he is far better than in my opinion. Just don't buy that he's technically good enough to be amongst the very best. I'd rather he stayed than went, for what it's worth - although he can be replaced with decent funds.
