This has led to several finals featuring two clubs from the same country: During the 1979–80 season, West Germany had five entrants including cup holders Borussia Mönchengladbach. All five managed to reach the quarter-final stage and both semi-finals ended up being all West German affairs. Ultimately, Eintracht Frankfurt defeated Borussia Mönchengladbach in the final. No West German club that season was eliminated by a non-German club. During the 1997–98 season, France had seven entrants: Strasbourg as winner of French Coupe de la Ligue, Nantes as third-placed team from French Division 1, FC Girondins de Bordeaux as fourth-placed team from French Division 1, Metz as fifth-placed team from French Division 1, and also Auxerre, Bastia and Lyon as 1997 UEFA Intertoto Cup Group winners. Nevertheless, only one, Auxerre, reach the quarter-finals, where they were eliminated by Lazio. Two clubs have managed to win consecutive UEFA Cups/Europa Leagues: Real Madrid in 1985 and 1986, and Sevilla
