UEFA fines Napoli

The European governing body has also threatened the Serie A club with playing a European match behind closed doors if the issues at its Stadio San Paolo resurface within the next five years.

A UEFA statement read: "Italian club SSC Napoli have been punished by the UEFA Control and Disciplinary Body for the inappropriate conduct of their supporters, insufficient organisation in the stadium and non-respect of UEFA directives related to stadium security at their UEFA Europa League Group F match against Swedish opponents AIK on 20 September."

Napoli will also be banned from selling tickets for parts of the main stand for its next European game at home to Dnipro on November 8 unless it can provide "a report from an independent construction company which confirms, with photographic evidence, that the necessary repair work has been carried out and that the aforementioned stands meet all the relevant spectator safety standards".

UEFA said if satisfactory repairs have not been carried out by November 6 it could prevent European matches taking place at the stadium.

Napoli has three days to appeal the decision.
