Juventus extended its lead in Serie A to 11 points after beating Fiorentina 3-0 on Saturday.
Rodrigo Bentancur and Giorgio Chiellini scored and Cristiano Ronaldo added a late penalty to condemn Fiorentina to its first defeat of the season.
Fiorentina dominated for large periods and tested Wojciech Szczesny several times before Juventus doubled its lead and essentially sealed the result.

Juventus appealed for a penalty in the 25th minute when Mattia De Sciglio’s cross hit Cristiano Biraghi’s trailing arm but, after reviewing the incident on the pitchside monitor, the referee ruled it unintentional.
The visitors took the lead shortly after and Ronaldo was again involved. The Portugal star took away two defenders with a clever run, allowing Bentancur to play a swift one-two with Paulo Dybala and finish into the bottom right corner.
Fiorentina fought hard for the equalizer and went close but Chiellini scored his first goal for two years in the 69th minute.
Juve’s second goal came from a rare source, but its third came from a natural goalscorer.
Fiorentina defender Vitor Hugo blocked Mario Mandzukic’s cross with his hand and Ronaldo stepped up to powerfully dispatch the resulting penalty. It was his 10th goal in his past 11 Serie A matches.
