Serie A defending champion, Juventus still struggling to get a consistent result in the league as they were beaten by Napoli this past weekend.
Both teams were looking for all three points that can kick start their season as both haven't had a good start.
However, it was Partenopei that made a brighter display early on as they got a one goal lead going into half time break through Lorenzo Insigne's goal.
Napoli kept on pushing forward in the second half as they eventually netted their second on 62 minutes from Gonzalo Higuain's finish.
Juventus did get themselves a lifeline when one minute later, Mario Lemina pulled one back, but it wasn't enough to stop the home team from collecting three points.
