Antonio Conte's Inter Milan tightened their grip on the Italian Serie A title on Sunday with fullback Matteo Darmian scoring the only goal in a 1-0 victory over Cagliari to stretch their ­winning streak to 11 games.

Champions Juventus consolidated third place with a 3-1 win over Genoa as Atalanta battled to a 3-2 victory over Fiorentina to stay fourth ahead of Napoli who won 2-0 at Sampdoria.

"We're starting to see the finish line," said Conte after Inter restored their 11-point lead on second-placed AC Milan who won 3-1 at Parma on Saturday.

Moroccan Achraf Hakimi came off the bench and set up Darmian to grab the winner with 13 minutes to go at the San Siro.

Romelu Lukaku set up Alexis Sanchez who thought he had broken the deadlock after quarter of an hour, but the goal was ruled out for offside.

Conte made a double ­substitution bringing on ­Hakimi for Ashley Young after 69 minutes, with Lautaro ­Martinez replacing Sanchez.

It paid off and minutes later as Hakimi combined with Lukaku to tee up Parma loanee Darmian to push Inter closer to a 19th Serie A crown after finishing runners-up last season.

Juve's nine-year reign looks set to end as they sit 12 points adrift of Inter and are now battling to stay in the Champions League berths with four points separating the second and fifth-placed teams.

Serie A top scorer Cristiano Ronaldo drew a blank to add to his frustration, as the ­Portuguese star failed to add to his 25 goals this campaign.

"It happens to everyone to get angry," said coach Andrea Pirlo. 

"Cristiano wanted to score at all costs because he's a champion who wants to stamp his mark on matches."

Dejan Kulusevski curled in the opener after four minutes in Turin.

Juve doubled their lead after 22 minutes when Federico Chiesa forced a Mattia Perin save with a Ronaldo follow-up coming off the post before Alvaro Morata sent in the rebound.

Gianluca Scamacca headed in to pull a goal back for Genoa four minutes after the break, with Marko Pjaca then ­missing two quick-fire chances to equalise for the visitors.

Substitute Weston McKennie sealed the win on 70 minutes for a valuable three points before this weekend's trip to Champions League rivals Atalanta.
