Paulo Dybala acrobatically hooked in a rebound and Blaise Matuidi scored from close range in the first 16 minutes. Cristiano Ronaldo could not add to his tally of three goals. Massimiliano Allegri's side, champions for the past seven seasons, maintained a three-point lead over Napoli at the top of the table, while Bologna remain in the relegation zone.
A tearful Cristiano Ronaldo was controversially sent off as Juventus claimed a hard-fought win at Valencia. The Portuguese forward, making his Champions League debut for Juve, appeared to grab Valencia defender Jeison Murillo's hair as they tangled off the ball midway through the first half and referee Felix Brych consulted his assistant behind the goal before showing the five-time Champions League winner a straight red card.
