AC Milan president Silvio Berlusconi is sure Alexandre Pato will stay at the club but admits Andrea Pirlo's future is less certain.
There have been suggestions further stars could leave San Siro this summer following Kaka's switch to Real Madrid.
A number of players, including Pato and Pirlo, have been linked with transfers to Chelsea, where former Milan boss Carlo Ancelotti now manages.
Berlusconi is confident Pato will enjoy an impressive 2009/10 campaign at Milan while he is hopeful playmaker Pirlo will also stay.
"We are going to see what we do with Pirlo, I hope that he is going to stay and I was the first to say so, but we must assess the situation," Berlusconi said on Milan Channel.
"Pato is going to complete an amazing career and I think that he can replace Kaka."
On the futures of Brazil forward Ronaldinho and experienced midfielder Massimo Ambrosini, Berlusconi said: "Ronaldinho will be fine this year.
"There is no problem with Ambrosini, who wants to extend his contract to another season."
Berlusconi also feels the club, under new boss Leonardo, will return to winning ways next term.
He added: "This year we have a great team, last season we wasted our finish by giving the ball away too often in decisive moments."
