Sinisa Mihajlovic has said that Mario Balotelli is still 'too fat' and is unlikely to start in the Milan derby.

The 25-year-old rejoined AC Milan from Liverpool on a season-long loan but lacks full match fitness ahead of tomorrow's clash.

Mihajlovic claims that Balotelli is training well but needs to lose some body fat to reach his optimum level of fitness.

"The problem is not his weight, but the fatty tissue," Mihajlovic is quoted as saying by FourFourTwo.

"He needs to improve his muscular mass and reduce the percentage of fat in his body. Weight and body fat are two different things - he should decrease the second.

"He has lost half a pound so far. In any case, he is training well and is positive."

The club face Inter Milan tomorrow at 7.45pm.
