Balotelli has impressed for Italy at Euro 2012. The 21-year-old scored two decisive goals in the semi-final victory over Germany.

"The way I see it he's worth, what the market wants," Mino Raiola told Sky Sport Italia.

"But remember that Balotelli is in a team that does not need to sell and therefore he has no price. If I really had to give him a value, I would say €250 million. I am crazy? Go and ask the club what there price would be....

"They have always said I'm crazy, but, in my opinion, at 21 the boy still has potential to be one of the best in the world. At the moment, after these Euros, he is surely one of the best in Europe."

Balotelli has previously been linked with the likes of AC Milan and Real Madrid.
