AC Milan vice president and commercial manager Barbara Berlusconi has said that reported Arsenal target Mario Balotelli is "not irreplaceable."
Balotelli, 23, has been linked with a summer transfer to Arsenal, with the player's agent this week failing to rule out a San Siro exit.
Berlusconi was asked about the Italy international's future, according to Football Italia, and cast doubt over whether he will stay.
She said: "Balotelli is a great player and a real Italian talent, but nobody is irreplaceable. We'll see what happens."
The future of Kaka is also the subject of conjecture after New Major League Soccer franchise Orlando City confirmed they are in "advanced discussions" to sign the playmaker.
Berlusconi said about the Brazilian: "Kaka made history with Milan and I know he needs to make this important decision with absolute calm. If he stays then we'll be happy, but we'll have to take it into account if he does want to go."
