Luciano Spalletti got the better of the club he once led to the Scudetto as Juventus beat Napoli 2-0 at the Allianz Stadium, with Kerim Alajbegovic and substitute Jeremie Boga both scoring from outside the box. The win lifted Juventus above their visitors, who had arrived level on 14 points, and extended their run of home clean sheets against Napoli to four matches.
