Napoli have been boosted with the return of defenders Kalidou Koulibaly and Kelvin Malcuit from their respective injuries.
Koulibaly suffered a hamstring injury against Parma in December which kept him out of action for two months while Malcuit tore his anterior cruciate ligament in October.
Although the Senegalese centre-back played against Lecce in February, he was dropped for their last five games including their Champions League first leg encounter against Barcelona.
On Tuesday, Malcuit, who is of Moroccan descent, and Koulibaly participated in some field work with the rest of the team.
