Have another look at the second goal QPR scored on Championship day. Mancini' reaction towards Nasri (and his effort!) will tell you everything you need to know!
He is a definite talent, just like hundreds of others who ply their trade for a decade in top teams, but his WILLINGNESS TO APPLY THAT TALENT TO THE TEAM ETHIC (yes, that's shouting!) seems lacking, and there is no room for self-centered, arrogant twats in Pep's City team...or many other teams, apparently.
He is on the wrong side of the age peak, and is not a player who relies on his fitness to add to his obvious talents. I expect that in 5 years, 10 is a definite, he will be a fat fuck with a young slut on his arm, solely because he has some coin! Oh wait, did I say years? I meant days, possibly hours!!!
