Defending champions Napoli defeated title rivals Inter Milan, moving to the top of the Serie A table.
The hosts took the lead at the Stadio Diego Armando Maradona through a first-half penalty scored by Kevin de Bruyne. Scott McTominay and Frank Anguissa also scored, securing Napoli's first win in three games.
This win comes after a league defeat by Torino and a midweek 6-2 thrashing by PSV Eindhoven in the Champions League.
However, there was a setback for Napoli as Kevin de Bruyne limped off the pitch soon after scoring. De Bruyne has four goals in eight games since leaving Manchester City.
Inter made a strong start, with captain Lautaro Martinez being denied from close range by Napoli goalkeeper Vanja Milinkovic-Savic.
Napoli's win marks a significant shift in the Serie A standings.
