Napoli have confirmed they will appeal against the decision to shut down two large sections of their San Paolo stadium.
Italy's Lega Calcio ruled on Monday that the stadium's Curvas A and B - which house Napoli's 'ultra' supporters - would be closed until October 31 as punishment for the behaviour of their fans on the opening weekend of the season.
Before Napoli's first game at Roma, a number of supporters vandalised trains and the central rail station in Naples before travelling to the capital. Once at the Stadio Olimpico, several Napoli fans were detained by police.
The Serie A club were also fined 10,000 euros as a result of the incidents.
A club statement read: ''SSC Napoli announces it has ordered lawyer [Mattia] Grassani to present an urgent appeal regarding the decision made by the sporting judge of the Lega Calcio on the partial closure of the stadium.''
The ruling has created a logistical headache for Napoli ahead of Sunday's home game against Fiorentina, with tickets having already been sold for the affected sections.
