Napoli fans have been barred from attending their UEFA Champions League play-off second leg away to Nice for security reasons, the French club said on Monday.
French police have banned Napoli fans from Nice's Allianz Riviera stadium and its "surroundings" for the August 22 clash on the grounds of "serious risks for the safety of people and property".
Italian authorities had already banned Nice fans from Wednesday's first leg at the San Paolo stadium in Naples.
The move by French police means an extra 3,100 tickets are available for home fans in what would otherwise be the visitors' section of the ground.
In 2015, rival fans clashed outside the Allianz Riviera ahead of a friendly between Nice and Napoli.
