It was a hard-fought clash but City made it three Champions League wins out of three against Napoli.
Early goals from Raheem Sterling and Gabriel Jesus had put Pep Guardiola's side in the driving seat in a high-quality encounter at the Etihad.
But Napoli showed why they had powered their way to the top of the Italian League by launching a second half fightback.
They narrowed the deficit with a 73rd minute penalty and gave City one or two scary moments in a tense last 15 minutes.
But the Blues held firm to make it nine points out of nine and move another vital step closer towards qualifying for the last 16.
