AC Milan coach Massimiliano Allegri is unsure if Antonio Cassano will make Euro2012.

Cassano is recovering from a minor heart operation.

"Antonio is above all a great champion. When he first came here, everyone was afraid of some crazy behaviour, but I was very happy to have him. Now he has settled in brilliantly. Mario Balotelli? Maybe he'd have the same reaction...

"Cassano is on the road to recovery after the heart surgery, though I don't know if he'll manage to be fit in time for Euro 2012. Now he needs to focus only on recovering," said Allegri.
