Napoli lost further ground to Juventus at the top of the Serie A table after stuttering to a disappointing goalless draw against Torino on Sunday evening.
Napoli were the dominant force throughout, but they found it increasingly difficult to break down a spirited Torino defence and were consistently denied by Salvatore Sirigu, who enjoyed an impressive game in goal for the visitors.
The likes of Arkadiusz Milik, Lorenzo Insigne and Jose Callejon all went close for Gli Azzurri, but none were able to find a way past Sirigu, who continued to frustrate the hosts right until the end of the match.
