The experienced midfielder has taken the time to praise the former Inter starlet and feels the striker will become a key figure at San Siro
The controversial striker joined the Rossoneri from Manchester City in the January transfer window, and netted twice on his debut to help his new club to a 2-1 win over Udinese.
Ambrosini is confident that there is still much more to come from the 22-year-old though, and feels he will become a key figure at Milan.
"In football terms Balotelli is beyond discussion," the midfielder was quoted as saying on the club's official website.
"Let's not forget that [Giampaolo] Pazzini has done so much for this team, but Mario will bring everyone a lot of satisfaction if he makes himself available to this team, and he will certainly do so..."
Balotelli will be looking to add to his tally at the weekend when Milan take on Cagliari on Sunday.
