The 27-year-old has revived his career on the French Riviera, finding the net a combined 28 times in 42 Ligue 1 appearances since the start of last season.
Plenty of other options remain on the table for the former Liverpool and Manchester City ace, however, as he will be available to purchase on a free contract by the time the summer transfer window opens for business.
"Mario is ready to return," Raiola told Rai Sport. "He has matured and is one of the top 10 strikers in the world and in Italy, he in number one.
"He is worth €100m but is available for free so therefore he's a bargain. I'm already talking to clubs from England and I have also spoken to Juventus, Roma, Napoli and Inter. AC Milan? No, because there is [Massimo] Mirabelli and I do not see eye to eye with him."
Balotelli has also previous taken in spells with Lumezzane and Inter, last competing in Italian football two years ago.
