Napoli completed their final training session at the Estadio do Dragao on the eve of Porto-Napoli.
The afternoon session focused on activation work followed by technical-tactical drills, as the squad made its last preparations for the match against Francesco Farioli's side.
There was positive news for the Azzurri with Kevin De Bruyne and Rasmus Hojlund both training with the group.
Sergej Milinkovic-Savic worked separately, following an individual training programme. The club report did not specify a reason or a timeline for his return to full team training.
