Bonucci headed the away team back in to the game
Leonardo Bonucci marked his second debut for the 'Old Lady' with a headed finish from a corner.
Juventus took the lead early in the game through Sami Khedira but then found themsevles behind following a Stepinski header and a penalty converted by Giaccherini either side of the break.
The Italian champions new that they had to fight back and were better going forward after conceding for a second time, with Cristiano Ronaldo particularly turning on the style at times.
A corner was conceded on the right side of the Chievo goal, which was whipped in and Bonucci flicked it home past Sorrentino in the Chievo net.
While he received a lot of criticism from Juve fans over the way he exited the club last year, that goal will go somewhere to clam tensions between him and the club's fans.
