Kalidou Koulibaly scored a late winner to help Napoli win 1-0 at Juventus and reignite Italy's Serie A title race yesterday.
Napoli trailed Juventus by six points last weekend but the Bianconeri drew at Crotone midweek, and two straight wins for Maurizio Sarri's team slashed the lead to a solitary point with four rounds left.
Juventus arguably have the tougher run-in as they face Champions League-chasing Inter Milan and Roma as well as Bologna and Hellas Verona.
Napoli play Fiorentina, Torino, Sampdoria and Crotone.
Napoli were aiming to boost their dream of a first title since Diego Maradona led the southern club to its only two Serie A championships in 1987 and 1990.
