1990–91 SSC Napoli season

SSC Napoli had a disappointing Serie A title defence, where captain Diego Maradona failed a drugs test and would not play for the club again. The reliable home form of the 1989-90 season disappeared, whilst the European Cup dream ended already in the Last 16 against Spartak Moscow. The team did, however, win the Supercoppa, which was the final title of the club's successful Maradona era.
