Lausanne Sports pulled off a major upset by defeating Italian Serie A side Fiorentina 1-0 in the UEFA Europa Conference League. In a match played on December 19, 2025, the Swiss club secured a famous victory against more fancied opposition. The decisive goal came against the run of play in the second half, as Lausanne capitalized on a defensive error to take the lead. Fiorentina dominated possession and created numerous chances but were repeatedly denied by an outstanding performance from the Lausanne goalkeeper, who made several key saves. The result was a historic one for Lausanne Sports and a disappointing start to the European campaign for Fiorentina.
