The 27-year-old forward is out of contract at Nice at the end of the season, having scored 21 goals in 29 games in all competitions this campaign.
Raiola claimed he had spoken to several clubs about Balotelli, but he ruled out a return to AC Milan for the 33-time Italy international.
"Mario is ready to come back to Italy. He is one of the 10 best strikers in the world, and the number one in Italy," he told RAI.
"He is worth €100m, but he is a free agent so he is a bargain.
On AC Milan, he added: "No, because there is [sporting director Massimiliano] Mirabelli and I can't talk with him, I'm not at his level."
