The Rossoneri vice-president revealed that negotiations are in place regarding the 30-year-old's departure from the club and admitted that an exchange is on the cards
It has been suggested that the Italy international will be used as part of a deal to bring in Pazzini from Inter and the Milan chief executive admitted that talks are ongoing.
"I will not deny something is stirring. Cassano asked us to be sold. The most likely solution is a swap," Galliani admitted in a press conference.
"There are negotiations in place, there is no doubt about that and we will see. As with all negotiations, they can conclude positively or negatively."
Galliani was asked about the rumours of a Cassano-Pazzini swap, but the executive simply smiled and stated: "I know nothing about it."
The comments came in the wake of the Rossoneri's 3-2 defeat at the hands of Juventus in the Berlusconi Trophy this weekend, of which Cassano did not play a part.
