Roma 1-4 Napoli: Defeat at the Olimpico for Ranieri's side

Diego Perotti equalised on the stroke of half-time for the Giallorossi to cancel out Arkadiusz Milik's early goal - only for Dries Mertens, Simone Verdi and Amin Younes to all score in the second period to decide the game.

At least the Giallorossi have an almost instant opportunity to make amends - they are back at the Olimpico on Wednesday, as they host Fiorentina in another important league game.
