Inter Milan survived its toughest test yet as it drew at Juventus 0-0 to stay unbeaten and on top of Serie A on Saturday.
Inter barely sighted the goal, and Samir Handanovic was certainly the busier of the two goalkeepers in the Derby d’Italia.
Wojciech Szczesny stepped in for the injured Gianluigi Buffon but he was mainly a spectator between the posts for Juventus.
Mario Mandzukic hit the crossbar but Juventus remained third, two points behind Inter and level with Napoli, which hosts Fiorentina on Sunday.
It was the first time Juventus has failed to score in 45 Serie A matches.
Juventus could have taken the lead with less than 10 minutes to go but Handanovic parried Mandzukic’s effort and the Croatia striker’s header on the rebound was cleared off the line by Miranda.
Ivan Perisic scored a hat trick as Inter beat Chievo Verona 5-0 last weekend but he almost netted at the wrong end in Turin. Gonzalo Higuain sent in a ball over the top to Cuadrado and Perisic’s header forced Handanovic to fingertip it over the bar.
Paulo Dybala, who surprisingly started on the Juventus bench, was brought on for the final 15 minutes but had little impact.
Cagliari recovered from two goals down to draw at high-flying Sampdoria 2-2 thanks in part to a bizarre goal from Diego Farias.
Unlucky Cagliari lost four players to injury before halftime, including goalkeeper Rafael during the warmup.
It was also 2-0 down at the break because of Fabio Quagliarella, who was set up both times by Gaston Ramirez.
However, Cagliari pulled one back 11 minutes after the interval when a clearance from Samp goalkeeper Emiliano Viviano ricocheted off the back of an oblivious Farias and into the back of the net.
Leonardo Pavoletti leveled four minutes later.
Cagliari moved seven points clear of the relegation zone, while Sampdoria remained sixth.
