AC Milan CEO Adriano Galliani has stressed Mario Balotelli must improve in order to earn a permanent move to the club.
Balotelli has scored just once in 15 Serie A appearances.
Balotelli is on a one-year loan from Liverpool.
"Mario is feeling well," Galliani told reporters. "He is desperate to stay here at Milan.
"But like I have said before, he does not merit a permanent deal at the moment.
"We really like Mario, but he has to convince us to earn a permanent deal."
Balotelli's contract with Liverpool runs until June 2018.
