It does raise questions, yet again, about who makes the decisions about transfers at that club. They've had a recent history there of friction between players, and between players and manager. Mancini is still trying to establish himself, and there will be lots of new faces anyway who will need to be knitted together into a team. Why bring in Balotelli? Not only is he a difficult player to manage, he actually seems to take pride in being difficult.
I think he's overrated. If he does come, he'll end up with five or six goals.
