Serie A—Stadio San Paolo, Naples
Napoli 2-0 Juventus
Scorers: Callejon (38'), Mertens (82')
Juventus sustained just their second Serie A loss of the season as Napoli ran riot at the Stadio San Paolo.
The Partenopei dominated throughout, Marek Hamsik shackled Andrea Pirlo and the home side took the lead through Jose Callejon's opportunistic, poked effort.
Dries Mertens, a second-half substitute, sealed the victory late in the second half, and but for Gianluigi Buffon's heroics it could have been more.
