The 36-year-old’s previous contract expired earlier this summer, but he will remain in Turin for another two years.
Giorgio Chiellini has signed a two-year deal with Juventus.
Centerback became a free agent this summer when his contract with the Serie A giants expired.
But the Turin club have confirmed that Italy International will still be part of the squad for next season, signing a contract that will run until 2023.
What has been said?
“The signing was a formality in the end, because as soon as I knew my body would continue to play me, both parties always wanted to be together,” Chileni told the club’s media channel.
“It simply came to our notice then.
“The close relationship between me and Juventus is above all. I had no doubt that I would stay here.
How long has Chileni been in the joints?
The Bianconeri captain joined Fiorentina in 2005.
He made 535 appearances for the club, winning nine Serie A titles and the Coppa Italia five times along the way.
But Chileni played a limited role for the team last season as injuries limited him to 17 Serie A matches.
However, he recovered in time to participate in Italy’s Euro 2020 campaign.
He played five matches in the competition as Azori won the trophy.
