Napoli are set to face an Empoli side on Wednesday who are fighting to avoid relegation and are also unbeaten in their last four home games in Serie A.
I Partenopei will be without one of their key players in Lorenzo Insigne, who suffered an injury in training last Friday. Raul Albiol is a long-term absentee following his knee surgery in February and Amadou Diawara and Vlad Chiriches are also out with muscle injuries.
The away side will be bolstered by the return of Piotr Zielinski who was suspended against Juventus.
Here's how Ancelotti's side could line up against Empoli:
