Palermo president Maurizio Zamparini revealed earlier this week an Italian club is among the contenders to sign Pastore.
The Argentina international is one of the hottest properties in the transfer market and is a reported target of Chelsea and Manchester City.
"Pastore? The Italian club which Zamparini refers to is not AC Milan," said Galliani.
Galliani also brushed aside ongoing speculation that Real Madrid midfielder Kaka would move back to the Rossoneri this summer.
The Brazil international has had a troubled spell with Madrid in which injuries and form have hindered his career.
The 29-year-old joined Madrid from Milan in 2009 and is under contract with the Primera Division side until June 2015.
"It is a very complex operation," said Galliani. "He (Kaka) has remained in our hearts but it objectively remains a difficult deal."
