He has scored only one Serie A goal in 13 appearances, and his displays are coming in for criticism.
Italian politician Roberto Maroni, a pal of Silvio Berlusconi, has hit out at the striker after his performance against Sassuolo at the weekend, a 2-0 losst.
He is quoted by CalcioNews24: "Balotelli was non-existent, he must go out. It was clear, he was lazy and did not commit himself, spinning around the pitch thinking about something else."
While guessing what goes through Mario Balotelli's head is a tough task, the striker must be worried over his lack of form, which has seen him net just two league goals in two seasons.
A place at Euro 2016 with Italy looks unlikely, and AC Milan are unliekly to push for a permanent deal based on the games he has played so far.
He will face a major challenge to rescue his Liverpool career in the summer, which will be even more difficult with no momentum from his Serie A return.
