AC Milan vice-president Adriano Galliani says that he does not expect to sell Antonio Cassano this summer, despite reports that the striker is unhappy at the San Siro.
Cassano is third choice behind Pato, Zlatan Ibrahimovic and has been linked with a transfer to gain more playing time at other Serie A clubs Fiorentina, Palermo and Genoa.
But Milan are keen to keep the Italian as they look to defend their title this season.
"Cassano is absolutely not for sale. If he doesn't request a transfer, then he is thoroughly confirmed within the squad,'' Galliani said. ''Clearly it could be a problem for him that in the lead-up to Euro 2012 he needs to play regularly, but his agent has not asked us to release him. If Cassano wants to leave, then he has to tell us that."
Milan are chasing a mystery man, known only as 'Mister X', during the transfer window but Galliani would not shed more light on the moves.
"We'll see what happens, as we already have a competitive squad, so we'll take an opportunity if it presents itself," he said. "Is it Kaka? That is an impossible move, so we cannot talk about it in positive terms."
Galliani did admit he was in negotiations with Palermo for Pastore, but could not match the €43m fee agreed with Paris Saint-Germain.
"We were tracking Pastore even before he came to Palermo and considered him an alternative to Kaka," Galliani told Sky Sport Italia.
"He has become too expensive now. Both he and Alexis Sanchez went abroad because it's impossible for Italian clubs to pay €45-50m for a player. If the new law on stadiums owned by clubs is not passed, then we cannot bring in the funds. That is the only big problem in Italian football."
