No that's true, it's all about desire. Since his first 4 years at United he has mellowed season on season. He has got sloppy, he hasn't been showing that passion.
The question is whether coming back will relight that passion. I can see the argument for but I worry he is past the point of no return. I would like to see the aggressive, swearing at refs, pissed off for being subbed/benched even granny shagging if that's what it takes
If we get that Rooney he will be worth every penny.
