City are now working as a team and they will only get better. I doubt they would want someone like Ibra especially that they are building for the future. For Milan Ibra is the center of play and he can carry them on his shoulders in this transitional period. He'd be the last to go out when this period is over. They'll keep building a squad until they have the right mix that doesnt need Ibra (like Mou did to Inter) then they will let him go. Ibra can make any mediocre team contenders as long as he is the center of play.
Milan is loaded with cash savings from wages that all their old guard would have earned had they continued.
Their front line is set with robinho, Ibra, cassano, Maxi and Sharaawy.. if someone is added it doesnt need to be a big name.
Their midfield is almost empty, meaning that next to montolivo, they'll buy and will probably buy atleast one big name. They have Prince, Aquaman, Montolivo, Flamini, Muntari and could add two of the likes of Sahin, Diarra, Mvilla, Ganso, Sissoko relatively cheaply + a few youngsters.
At the back they have only Silva and Abate as starters they'll have to buy plenty with atleast one quality CB.
They have a real challenge ahead of them.
