Mario Balotelli has been urged to show responsibility at Euro 2012 by one of his Italy team-mates.
Midfielder Thiago Motta, who also played with the striker at Inter Milan, says the 21-year-old can make a difference - if he behaves properly.
Motta, who now plays for Ligue 1 side Paris Saint-Germain, said: "We need Balotelli to work for the team, and to show responsibility.
"Only like that can he make the difference, and I'm sure he will."
The striker is expected to be passed fit after suffering a thigh problem on Monday. He only joined his Italy team-mates for the second half of Tuesday's training but coach Cesare Prandelli is confident he will be fit for Sunday's opener with Spain.
Balotelli has already attracted attention ahead of the tournament,
claiming he will walk off the pitch during a match if he is racially abused,
as well as opting to wear his full family name of Barwuah Balotelli on his shirt.
Euro 2012 will be Balotelli's first international tournament, and Motta believes the striker must focus on football when he steps on to the pitch.
"He must help us, especially on the pitch because, off it, he can be the same as always," said Motta.
"Balotelli makes me just as angry now with his jokes as he did when he was at Inter. But away from the pitch he is a good lad."
Italy will open their campaign
against current holders Spain in Gdansk on 10 June.
