Defender Raul Albiol scored the only goal of the game as Napoli picked up a slender 1-0 win over Genoa at the Stadio San Paolo this evening.
The Partenopei made the most of Juventus's surprise stalemate at SPAL on Saturday night by picking up the win that takes them back to within two points of the Serie A summit in a tight title race.
Napoli, with just one point to their name from the last six on offer prior to tonight, got the job done through Albiol's 72nd-minute header.
Without a win in this fixture since January 2012, Genoa made a positive start and gave their opponents a scare when Darko Lazovic picked out the side-netting with his shot.
Dries Mertens and Andrea Bertolacci also came close with their attempts, while Nicolas Spolli clipped the crossbar with his free header from all of five yards.
Both teams continued to squander chances, as Allan slipped when getting in a shot just before half time and Lorenzo Insigne looped a header against the frame of the goal.
The post once again came to Genoa's rescue early in the second period, with Mertens this time rueing his luck after getting a shot in from the edge of the box.
Goran Pandev and Mertens were the next players to pass up decent openings but, just when the match looked destined to be heading towards a goalless conclusion, Albiol diverted Jose Callejon's corner home at the near post.
Only a goal-line clearance from Davide Biraschi prevented Insigne from doubling his side's tally, but the Partenopei held on at the other end to inflict a third successive defeat on their opponents.
