Would love to see him back here. All those asking for youth youth youth need to remember that youth has to be blended in with experience. This is what has made Ferguson the success that he has been (well, that and money) - he's understood the right balance in the squad. We have a forward line of Carroll (young), Suarez (new to England, although not showing it!), Ngog (young and on his way out?), and that's it. Someone like Bellamy would be a great addition.
That said, I didn't see much of him last year at Cardiff, so I'm not sure whether his standard has dropped, and if so by how much. If he is close to the player he was even two years ago for City, then I'd take him back in a shot.
