The 33-year-old's future has been in doubt, but he recently committed himself to the Turin giants and is in North America on the Italian side's pre-season tour.
"I have never thought of coming here [United States] to end my playing career," he told American reporters.
"I’ll stay at Juventus for as long as they trust me."
However, the ex-Parma goalkeeper admitted that a future coaching role may appeal although that was still some way off. He added: "In three or four years I’ve got the crazy idea in my head that I’d like to be the coach for USA or China. Both would be incredible experiences."
