The legendary Juve player has been at the club for 18 years but is out of contract at the end of the season.
The 36-year-old has confirmed that talks are ongoing over an extension for next season, although he is not yet certain whether he will sign a new deal.
"Things depend on the two parties," Del Piero told Sky Italia.
"I think everything will be decided in a short time and there will be an announcement from the club.
"I am not certain of staying, otherwise I would already have a contract, but my priority is certainly Juventus.
"They have been my history and I don't think I'd be able to play for another Italian side, so I hope to find an agreement to stay."
Del Piero joined Juve from Padova in 1993 and is currently the club's highest-ever goalscorer.
In October last year, Del Piero scored the record breaking179th goal to fire Juve to a 2-1 victory against Milan in the San Siro.
