A first-half header from Mario Manduzkic proved enough for leaders Juventus to extend their unbeaten run in Serie A to 21 matches with a 1-0 victory over Empoli on Saturday.
Striker Manduzkic was picked out by Paul Pogba's inch-perfect cross in the 44th minute, allowing the Croatian to break the deadlock with just his seventh league goal of the campaign.
Massimiliano Allegri's side picked straight up from where they left off before the international break, recording a seventh successive home win in Serie A without conceding a goal.
They barely missed a beat despite being without Leonardo Bonucci, Alex Sandro and Sami Khedira through suspension, while forward Paulo Dybala was missing from the squad due to a muscular injury.
The champions now sit six points clear at the summit, although nearest rivals Napoli can cut the gap in half with victory away at Udinese on Sunday.
Empoli, meanwhile, have now failed to register a win in their last 12 league outings, a worrying run that has seen them slip into the bottom half of the table.
They had their opportunities to strike first in a lively opening half that could easily have contained more than one goal.
Mandzukic had fired a left-footed drive too close to goalkeeper Lukasz Skorupski after being set free by a beautifully disguised reverse pass from Pogba, but the same duo combined again to break the deadlock just before the break.
Frenchman Pogba's clever footwork on the left created enough space for him to drift over a teasing cross that his team-mate gratefully steered into the right side of the net.
Juventus' Alvaro Morata also hit the woodwork with a curling attempt from outside the area, but Empoli were not without opportunities at the other end.
Riccardo Saponara wasted their best opening, the midfielder blazing over from close range after the ball had dropped perfectly into his path at a corner.
Visiting captain Massimo Maccarone - who scored his side's goal in the 3-1 loss in the reverse fixture - also failed to get a header on target against a Juventus defence that included Empoli old boy Daniele Rugani.
Morata was denied early in the second half by Skorupski, although the goalkeeper nearly gifted Juventus a second goal with an air shot when trying to make a clearance outside his area. He was fortunate no opposing player was close enough to seize on the mistake.
Juventus should have made sure of the win in injury time, only for Skorupski to somehow block substitute Kwadwo Asamoah's point-blank effort after Morata's low drive had been parried.
Pogba and Simone Zaza also went close to settling any late nerves for the home side, yet one goal proved enough for Allegri's shorthanded squad to clinch the points.
Key Opta stats:
