Bullshit, Pato is quality, no doubt at all about that. How he is one dimensional is simply beyond me?! Injuries are the only thing stopping him from being recognized as a top striker.
That being said, i do think it could be very useful for them to sell him. He's extremely injury prone and as a young prospect that still hasn't fully reached his potential but has shown glimpses of what he's capable of when fit(and he's capable of a lot), i think he could fetch them a decent sum. As Treq said, Boateng doesn't really cut it as an AM. He's energetic and makes good runs, but technically he leaves a lot to be desired. I don't think he's capable of being a good CM in a 3 man midfield, as he doesn't have enough discipline or intelligence for the role. I think he is an AM, just not a very good one. Having him on the bench for another more technical AM would do Milan a lot of good. Still, i think if Milan buys Pato, then replacing him with another good striker(Cassano is out for god knows how long and Robinho is terribly inconsistent) and buying a CM that can actually pass the ball(Aquilani doesn't cut it) is more of a priority than getting an upgrade to Boateng.
