"I've signed my first blank contract with Juventus," said the 36-year-old Juve captain, out of contract in June, said in a video on his official website.
"I'll sign my last one to wear this jersey blank too," he added after admitting to having been stung by rumours he was holding the club to ransom.
"The driving force in my career has always been a deep love for football, for the Juventus colours and for its fans," he said.
"It's not about money. I've earned a lot in my life, though I could have earned more if I'd accepted certain offers."
"I spoke with the president (Andrea Agnelli) not about financial matters but my willingness to make myself available for next season," said Del Piero.
"My passion and my will to win that has been with me from the Viareggio (youth) tournament to the World Cup, not to mention Serie B," he added. "My ties to the colours and the fans cannot be measured in numbers."
