Having been given a day off following Tuesday's Champions League win over Eintracht, the Napoli squad reported back for duty on Thursday morning.
The Azzurri are now focused on domestic action once again, with a trip to the Stadio Castellani to face Empoli next up on Saturday evening.
The players began with a gym warm-up followed by some fitness work on pitch 2.
Afterwards they took part in some technical and tactical drills before finishing with a mini-match.
Giacomo Raspadori is still having physiotherapy.
On Friday the team will train again in the morning and set off for Empoli in the afternoon.
