Napoli took part in a morning training session at their base in Castel di Sangro.
The players started the session with a warm-up in the gym before working on tactics out on the pitch.
Luciano Spalletti's men then headed back into the gym for more fitness drills.
The session concluded with a small-sided match as well as target practice. Fabian Ruiz was back involved in the full session.
The squad took the afternoon off. Wednesday sees Napoli take part in a double session behind closed doors.
