Napoli's hopes of closing the gap on Juventus at the top of Serie A to two points were dashed on Sunday following a subdued performance in a 0-0 home draw with Sampdoria.
Fiorentina, shaping up as rivals to Napoli in the chase for a Champions League spot, got back to winning ways with a 4-1 thrashing of dismal Inter Milan.
With leaders Juve losing 1-0 at AS Roma on Saturday, second-placed Napoli were looking to put the pressure on their Turin rivals and bounce back after a 3-0 home Europa League defeat by Viktoria Plzen.
After a minute's silence to remember former Napoli player Carmelo Imbriani, who died of cancer on Friday at the age of 37, it was the visitors who came out in determined mood with Gianluca Sansone going close.
Napoli responded well, though, with Lorenzo Insigne letting fly from distance and Edinson Cavani fluffing a shot into the arms of goalkeeper Sergio Romero.
Goran Pandev came off the bench to link up nicely with Marek Hamsik whose powerful shot was only kept out by a full-stretch Romero.
Juventus, however, remain in touching distance just four points above with the two sides due to meet next month.
Goals from Adem Ljajic and Stevan Jovetic ensured a comprehensive win for Fiorentina over Inter in front of an ecstatic home crowd.
Fiorentina dominated the first half and it was only a fine display from keeper Samir Handanovic that kept the scoreline respectable.
Fiorentina took the lead in the 13th minute after Jovetic flicked a cross by Manuel Pasqual to Ljajic who got in front of defender Juan Jesus to beat Handanovic with a diving header from close range.
Jovetic then shrugged off the attentions of Andrea Ranocchia before curling in a fine shot from the left-hand side of the penalty area with the keeper rooted to the spot.
The Montenegrin got his second, set up by a neat Alberto Aquilani back heel that left him free to hit a powerful right-foot shot past Handanovic and Ljajic made it four in the 65th minute.
Antonio Cassano's late consolation aside, this was humiliating for Inter who face the remainder of the season without injured striker Diego Milito.
There were also leapfrogged by city rivals Milan who sit fourth in the standings, rejuvenated by former Nerazzurri player Mario Balotelli and with the Milanese derby looming next weekend.
Struggling Pescara lost 2-0 to Cagliari and Torino earned three points with a 2-1 home win over Atalanta.
