I'm not convinced Mancini is going to go out and buy a "centre forward." I think he fancies a "forward midfield" type player, as it creates considerably more fluidity and gives him more opportunities to move people around. As we have seen from other signings, he believes players should be able to play in numerous positions, so that he can change the team tactically without having to make a couple of substitutions. THAT is why Gourcuff is such an interesting recent rumor.
As we have seen from Barca, they have TONS of goals coming from midfielders, ALL of whom are 5 foot nothing. Arsenal do the same kind of thing, which is why Bendtner can't get a regular game even when others are out injured.
Anyway, I would not be surprised to NOT see him go for an out and out center forward. It's not like that is what Tevez is, either!
