Inter Milan defender Marco Materazzi has told Mario Balotelli "the door is open" if he wants to leave the club.
Balotelli is one of the most highly rated young strikers in Europe, but there are questions over his attitude and that has led to suggestions he could leave the club.
Stories surfaced again this week when the player was excluded from the squad to face Chelsea on Tuesday after a reported disagreement with coach Jose Mourinho.
Balotelli's agent, Mino Raiola, has told the striker he "must always behave like a professional" if he is to have a future at Inter and Materazzi has now suggested he should improve his attitude.
Asked if he had a message for Balotelli after the victory over Chelsea, Materazzi told Sky Sport Italia: "He should send one to us instead and thank his team-mates who got him to the quarter-finals.
"If he wants to be a part of this group, we are happy because he is a really strong player, but if he wants to go somewhere else, the door is open. The president has already shown that he won't hold back anyone who wants to leave.
"It's not true that we don't love him - we love him a little too much. He must be a fan of this team because the president treats him like a son, and so do I. This is our group, if he wants to be a part of it."
President Massimo Moratti has backed Mourinho over his decision to axe Balotelli but insists the player still has a future at the club.
"Mourinho made the right decision, so it means someone else did not do the right thing for the club," he said. "As I consider Balotelli to be a player of immense talent, I trust he will now prove he is a great professional and Mourinho will be very happy to field him again."
