Paul Pogba sustained Juventus' seemingly inexorable march towards a fifth straight Serie A title by completing a 2-1 comeback victory over AC Milan at San Siro.
The reigning champions suffered an early setback when Alex planted a bullet header beyond Gianluigi Buffon but Mario Mandzukic soon replied.
Then, midway through the second half, France midfielder Pogba bamboozled 17-year-old Rossoneri goalkeeper Gianluigi Donnarumma with a looping winner as Juve remain unbeaten in the league since October.
Massimiliano Allegri's men are now nine points ahead of Napoli with six games remaining. Milan remain in sixth, seven points shy of a Europa League spot.
Mauro Icardi's second-half goal spared Inter Milan from embarrassment against 10-man Frosinone.
The Argentine struck the only goal of a 1-0 Nerazzurri victory at the Stadio Matusa before Frosinone's Leonardo Blanchard was dismissed for picking up a second yellow card.
Ivan Perisic's cross beat the entire home defence and met Icardi's head, allowing him to register his 13th goal of the season in the 74th minute.
The win gives Inter a fighting chance of snatching the final Champions League place from in-form Roma, who are five points better off ahead of their Monday night meeting with Bologna.
Last year's Serie B runners-up Frosinone remain a point shy of safety and could be cut adrift in the drop zone if Palermo can beat Lazio in Sicily on Sunday night.
Blerim Dzemaili poured cold water on Sassuolo's quest for a Europa League place by firing Genoa to a 1-0 victory at the Mapei Stadium.
Seventh-placed Sassuolo are hot on AC Milan's heels but missed the chance to replace them after suffering only a third home defeat of the season.
Genoa goalkeeper Mattia Perin made a fine save to deny Nicola Sansone before, in the 42nd minute, Dzemaili turned Tim Matavz's shot home after the Slovenian's effort hit a post.
Chievo substitute Sergio Pellissier struck a blow to Carpi's hopes of securing a second season in Serie A.
The striker clambered off the bench to secure a 1-0 victory at the Stadio Marc'Antonio Bentegodi, after Carpi had looked good value for a point.
Goalkeeper Vid Belec could not keep Pellissier's conversion of an Alessandro Gamberini assist out of his net in the 87th minute, and Carpi were left dangling just above the drop zone.
