Early goals from Raheem Sterling and Gabriel Jesus saw Manchester City maintain their winning start in the Champions League with a 2-1 victory over Napoli.
City struck twice in the opening 13 minutes at the Etihad Stadium to set themselves up for a result that lifted them six points clear of the Serie A leaders, and their supposed chief rivals, in Group F.
Napoli hit back strongly with Dries Mertens having a penalty saved before Amadou Diawara did score from the spot, but City survived a nervy finish.
Pep Guardiola's men arguably should have put the game beyond reach in the opening half-hour, as Kevin De Bruyne also hit the bar and Jesus was denied a second on the line.
