Experienced Italian centre-back Leonardo Bonucci has signed a new three-year contract extension with Juventus.
The 28-year-old's previous deal was due to run until 2017, but the fresh terms have contracted the defender to Juve until at least 2020.
"It's the start of a new era. I'm here to offer my years of experience to help those who have joined the club," he told the club's official website.
"Juventus have a long-term plan. We're seeing a new generation coming through with quality young players. We've maintained our strong spine. This is vital for us to build on and go in search of further successes.
"I've had plenty of great times in these past four years. The goal against Roma was an important moment. Winning a fifth Scudetto in a row will be tough but we've got the right motivation to tackle this challenge."
Bonucci, who joined Juve from Bari in 2010, has made over 200 appearances in all competitions for the Old Lady.
