The Bianconeri boss, who recently won a second successive Serie A championship with the Turin-based outfit, has put pen to paper on a deal that expires in the summer of 2018
Head coach Massimiliano Allegri has signed a new deal at Juventus that ties him to the Serie A champion until 2018, the club have confirmed.
Allegri joined the Turin giants in July 2014 following a three-and-a-half-year spell at AC Milan and has built on the success of predecessor Antonio Conte by leading Juve to its fourth and fifth successive Scudetti.
The 48-year-old had 12 months remaining on his previous deal but both he and the club was eager to extend his stay with the Bianconeri.
