Marseille is the only French club to win the UEFA Champions League. Olympique de Marseille defeated AC Milan 1–0 in the 1993 final at Munich’s Olympiastadion, becoming the first and still only French European champion.
The winning goal came from defender Basile Boli, who headed in from a corner shortly before half-time. Marseille’s goalkeeper Fabien Barthez made important saves, while captain Didier Deschamps helped lead the side through a difficult final against Milan’s celebrated defense and attack.
The triumph followed Marseille’s controversial 1993 domestic season, during which the club was found guilty of a match-fixing scandal involving a French league game. The scandal led to the club being stripped of its French title and relegated, but it did not erase the Champions League victory.
Paris Saint-Germain reached and won the Champions League much later, in 2025, so the wording “only one” is now historically outdated if the question is intended to remain current. For the 1993-era fact represented by the stored answer, Marseille is correct; as a live present-day question, the item is time-sensitive and should be reviewed.
