Paulo Dybala scored twice as Juventus opened up a 10-point lead at the top of Serie A with a thumping 4-1 win against Palermo.
The Argentinian also set up fellow countryman Gonzalo Higuain for his 19th goal of the season as defender Leonardo Bonucci enjoyed an easy ride on his 300th appearance for the Black and Whites.
The home side had already struck the outside of a post through the impressive Dybala when they took a 13th-minute lead. Midfielder Claudio Marchisio pounced on a loose ball in the penalty area to rifle a shot into the top corner.
Palermo's response came from Ilija Nestorovski but his low drive was palmed around the post by Gianluigi Buffon.
Massimiliano Allegri's men come close to doubling their lead in the 21st minute but Palermo goalkeeper Josip Posavec managed to keep out Sami Khedira's volley from point-blank range.
Dybala scored a stunning second five minutes before half-time, curling a free-kick into the top right-hand corner from 25 yards.
Juventus continued to dominate after the break and Higuain made it three with a dinked finish from Dybala's superb through ball in the 63rd minute.
A collision involving defender Edoardo Goldaniga and goalkeeper Posavec saw the latter receive treatment before carrying on.
Substitute Juan Cuadrado had the chance to seal victory for Juventus with three minutes remaining but his angled drive was beaten away by Posavec.
That was left to Dybala, who side-footed in a fourth from Higuain's intelligent back-heel, but there was still time for Palermo to snatch a consolation through Ivaylo Chochev's header.
