According to Sky Sport Italia, the Serie A side have identified the 20-year-old Ivory Coast international as a potential winter transfer target.
Napoli currently occupy 10th place in the Italian top flight after 11 matches and are eager to reinforce their midfield options.
Zabi joined Paris FC from Stade de Reims for €20 million last summer but has struggled to establish himself under manager Liam Rosenior.
Despite making eight Ligue 1 appearances this season and registering one assist, the midfielder has yet to start a league match.
Napoli are hoping to capitalise on his limited playing opportunities to secure his services.
