I think he can get fit again. For me, I agree his halo has slipped over the last couple of years - didn't like his behavior over playing for Belgium seeming to be more important than City, and the rumours about his activism in getting rid of managers (although they are just rumours) but he will always be the guy who was always going to win that header against United that, were it not for the QPR insanity, would be considered the moment we ended our title drought.
I've never seen desire quite that strong from any player, before or since.
Hoping he can put the bad stuff and injuries behind him and go on to be the immortal City legend he deserves to be
