The French striker pledged the rest of his career to the Italian side earlier this summer.
“I will leave Juventus at the end of the season,” Trezeguet told the press.
“I have made a decision with my family and I will leave after 10 years of living in Turin. I want to go back home. I don’t know whether it will be France or Argentina.”
“I want to leave Juventus as a winner,” added the hitman.
“There will be no problems with my contract. I have informed the club.”
Trezeguet’s contract is due to expire in 2012.
