AC Milan vice-president Adriano Galliani is at a loss to explain the discontent his star strikers are expressing.

Zlatan Ibrahimovic raised some doubts over his long term future last week by suggesting he was getting tired of the game, while Antonio Cassano revealed that he plans to retire in three years.

"I don't know what's happening to Ibrahimovic and Cassano," said the Rossoneri Vice-President on Wednesday. "I'm not a psychologist.

"However, I talk to the players and everything is going very well. There is nothing to be worried about.

"Ibrahimovic was desperate to come back to us after international duty, despite what some people were suggesting."
