Napoli exorcised some of the ghosts of last season by beating Fiorentina 1-0 in Serie A action on Saturday.
When the two sides last met, Napoli lost 3-0 -- a week after beating Juventus in Turin -- and effectively handed the title to the Bianconeri.
Napoli also needed to recover from another 3-0 defeat, after losing by that scoreline to Sampdoria before the international break.
Lorenzo Insigne broke the deadlock 11 minutes from time. Arkadiusz Milik sent a deft chip over the defense and Insigne side-footed it across into the bottom left corner.
Fiorentina had won their two previous matches.
It was a first clean sheet in four matches for Napoli, who let in every shot on target in their three previous games.
