City appear favourites for the Italian's services after manager Roberto Mancini admitted he would jump at the opportunity to bring him to Eastlands.
The pair worked together during Mancini's spell in charge of Inter, and the 19-year-old has fallen out of favour since his departure.
Speaking on the prospect of a move to the Premier League, Balotelli told Corriere dello Sport: "Roberto Mancini? He's a great coach, I debuted in Serie A with him because he is a great friend.
"If he and (Sir Alex) Ferguson want me, it means I'm not as bad as I thought.
"United is a great club. They have not seen the real Balotelli, for sure I need to learn and achieve more goals. I want to win the Golden Ball in 2011. As for the future, I always say I don't know."
