Milan completed the signing of Genoa midfielder Kevin-Prince Boateng yesterday.
"At the start we had some difficulties, but at the end found an agreement that I think is fair and right for both parties," said the Milan Vice-President.
"Both Marco Amelia and Alberto Paloschi are also entirely owned by Milan. The latter will certainly remain, as he'll be important over the summer when Alexandre Pato and Robinho are in the Copa America.
"I don't think Cassano has any particular problems and his agent hasn't said anything. Ibrahimovic will certainly stay at Milan. Every now and then Mino Raiola likes to joke around, but Ibra is going nowhere."
