Not content with moving back to the top of Serie A, Napoli also boosted their credentials as Italy's most entertaining team by crushing third-placed Lazio 4-1 yesterday.
Napoli recovered from an early goal down to level at the end of the first half and then blew Lazio away.
Maurizio Sarri's team moved back to a point above six-time defending champion Juventus, who won at Fiorentina 2-0 on Friday.
Lazio remained third after their third successive league defeat, seven points behind Napoli, and could be overtaken by Inter Milan and Roma today.
Earlier, AC Milan beat relegation-threatened Spal 4-0, and Atalanta drew at Crotone 1-1.
Lazio got off to the perfect start as Stefan de Vrij stuck out a foot to prod Ciro Immobile's cross past Pepe Reina and give his side a third-minute lead.
De Vrij also opened the scoring when Lazio lost 4-1 to Napoli earlier in the season.
Napoli levelled in the final minute of the half when JosÃ Callejon brought down a long free kick from Jorginho and fired it into the bottom left corner.
Napoli dominated after the break and took the lead in the 54th as Lazio defender Wallace turned Callejon's cross into his own net.
