Inter Milan president Massimo Moratti has claimed that AC Milan are taking a "gamble" by signing Mario Balotelli.
The striker is expected to complete a move from Manchester City before the January transfer window closes on Thursday night.
"He's a Milan gamble, we will see how it ends," Moratti told reporters. "It could be a good move for them."
Balotelli left Inter for Manchester City in 2010 for around £20m.
