Trezeguet to leave Juve next summer
"I've decided to end my adventure at Juventus in June," the 31-year-old, who grew up in Argentina, told reporters.
"I spoke about it first to my family and we decided to return home. I don't know (whether to France or Argentina). After 10 years here at Juventus I think it's the right time to leave."
The striker, part of France's victorious 1998 World Cup and Euro 2000 campaigns, joined Juve from Monaco in 2000.
He won the 2002 and 2003 Serie A titles in Turin and his goals helped the club back into the top flight after they were relegated and stripped of two league crowns in 2006 for their part in Italy's match-fixing scandal.
Trezeguet was linked to AC Milan in the close season after falling down the pecking order under former coach Claudio Ranieri last term but he said he could not betray Juve by moving to their Serie A rivals.
New boss Ciro Ferrara did not field him in Juve's victories in their first two league games this season but the Frenchman remained upbeat.
"I haven't played much up to now, but my time will come," he said. "The bench is a stimulant for me to train and give my all. I'm going to enjoy this season. I don't feel cast aside."
