Unbeaten Inter Milan remain top of Serie A after a goalless draw with champions Juventus.
Juve, who have won the past six league titles, would have gone top with a win and had the game’s main chances.
Mario Mandzukic hit the crossbar with a header, and forced a number of saves from Inter keeper Samir Handanovic.
Serie A’s top scorer Mauro Icardi was very quiet and Inter only forced one save from Wojciech Szczesny, who played because Gianluigi Buffon was injured.
Napoli – who had topped the table until losing to Juventus 1-0 last weekend – can go top again if they beat Fiorentina at home on Sunday (14:00 GMT).
