The Azzurri reported back to the SSC Napoli Konami Training Centre on Tuesday after two weeks in Castel di Sangro.
The champions are preparing to kick off their 2023/24 Serie A campaign at Frosinone on Saturday 19 August (18:30 CEST).
Starting with a warm-up routine in the gym, the squad then moved outside for some fitness work.
After that, the lads worked on technique and played a mini-match with small goals, before finishing with tactical drills.
Gianluca Gaetano joined in with the others for part of the session and trained partly on his own.
Frank Anguissa followed an individual programme on the pitch.
