Pazzini is no longer in the plans after a season and a half at Inter.
Milan are looking to bolster their attack for the coming season after the sale of Zlatan Ibrahimovic and it appears that it will be either Pazzini or Juventus' Alessandro Matri who joins the club. It looks like Milan would be willing to do away with a striker to get Pazzini.
Cassano has been visibly unhappy at Milan since the sales of Ibrahimovic and Thiago Silva. He feels that Milan have no ambition for the coming season.
Pazzini, who scored 11 goals in 17 matches after his move to Inter from Sampdoria in 2011, scored only five times last season in 33 games and is out of the plans at Inter after Andrea Stramaccioni left him out of the squad for this season's UEFA Europa League.
AC Milan's options are limited in the transfer window after using their two non-EU passport spots on Brazilian goalkeeper Gabriel and Colombian Christian Zapata.
Milan could also move for Villareal striker Giuseppe Rossi, but the American-Italian is unavailable until about February due to a knee injury. Despite being unable to play, Rossi wants to move from Villareal due to the club's relegation to the second division in Spain.
