When Lazio refused to play Barcelona
In October of 1975, Lazio was set to face Barcelona away in the UEFA Cup. However, after the fascist Franco regime had assassinated five political dissidents, there were talks of the match not being played. In fact, Umberto Lenzini (the Lazio President at the time) called Franco Carraro (President of the Football League) and Artemio Franchi (Head of the FIGC) in order to obtain support for the Biancocelesti refusing to play the match against Barcelona in support of the Catalonia region. Lazio President Lenzini later publicly declared that Lazio would not travel to Barcelona and that they accepted any sanction for this; they did not show up at the Camp Nou and the game was decided off the pitch.
