Earlier, Ciro Immobile, Europe's leading marksman last season, was on target again with his sixth goal of this term as Lazio won 2-1 at promoted Spezia.

Juventus struggled throughout a first half in the derby that saw Nicolas Nkoulou glance in a loose ball on nine minutes as Torino striker Simone Zaza forced a fine save from Wojciech Szczesny.

Juve fired a first telling shot on target from Federico Chiesa in the 77th, one minute before substitute Weston McKennie nodded in the equaliser.

Leonardo Bonucci also headed in a Juan Cuadrado cross with one minute to go.

It moved the champions into second place on 20 points, three adrift of leaders AC Milan, who play Sunday at Sampdoria.

Torino stayed in the drop zone on six points from 10 games as their coach Marco Giampaolo returned after coronavirus quarantine.

Cristiano Ronaldo, who failed to impress and stayed rooted on eight league goals, received the best Serie A player award for November - his third recognition in as many seasons at Juve.

At Spezia, Lazio's European Golden Boot winner Immobile, who has now scored in each of his last five league games, struck in the 15th minute off an assist from Sergej Milinkovic-Savic.

The Serbian Milinkovic-Savic then curled in a free kick home as the Romans got the most from their rare first-half chances, while the aggressive newcomers were twice denied by the post.

M'Bala Nzola kept the hosts in the game when he got the better of Francesco Acerbi and struck into the far corner, but the Ligurians could not find an equaliser and stay in 15th place with a four-point buffer to the drop zone.
