Cassano has been with the Rossoneri for 18 months but has now decided that he would like to go elsewhere and AC Milan are ready do business with their city rivals.
A swap deal involving Pazzini is understood to be on the agenda as he is the type of out-and-out striker that AC Milan are lacking following Zlatan Ibrahimovic’s departure, while Inter want a player with Cassano’s creativity.
AC Milan chief executive Adriano Galliani told Mediaset: “There is a negotiation ongoing with Inter, it is useless to deny it.
“In the past there have been many exchanges between the two Milan’s clubs.
“There are two weeks until the end of the market. Something will happen.”
Galliani added on the Milan Channel: “Antonio has asked to be sold, let’s see what happens. The most probable scenario is a swap.”
AC Milan head coach Massimiliano Allegri is resigned to losing Cassano and has admitted that he is an admirer of Pazzini, although he has indicated there could be other options.
“I’m sorry for Antonio because he is a player with sublime qualities, but he wanted to go away and I think it is wrong to keep a player against his will,” said Allegri.
“There is a negotiation in progress and we expect developments.
“Pazzini? He is definitely a great striker, but there are many high-level forwards in Italy who could be right for us.”
