Napoli were sunk 1-0 at Torino by old boy Giovanni Simeone on Saturday as they struggled without the injured Rasmus Hojlund and Scott McTominay, who may also both miss out on a Champions League clash at PSV Eindhoven.
Simeone, who helped Napoli win Serie A in 2023 and last season, netted the only goal in the 32nd minute of a tense game in Turin which gives Roma the chance to go out on their own at the top of the league.
The 30-year-old also scored the winner in Torinos 1-0 home victory over Roma in September and he took his third goal of the season brilliantly, capitalising on a fortunate ricochet to skip past Giovanni Di Lorenzo and Napoli goalkeeper Vanja Milinkovic-Savic and shoot home.
