Bayern Munich lost on the opening day of the Bundesliga season for the first time since 2001 as they went down 1-0 at home to Borussia Monchengladbach.
Monchengladbach, who beat Bayern by the same scoreline in the first game ten years ago, repeated history to spoil Jupp Heynckes' third debut in charge of the Bavarians.
It proved to be an even worse bow for Bayern's new number one Manuel Neuer as his glaring error allowed Igor de Camargo to score the only goal of the game in the 62nd minute.
Defensive failings cost Bayer Leverkusen as they opened their Bundesliga season with a 2-0 defeat to Mainz.
Goalkeeper Fabian Giefer's poor clearance allowed Sami Allagui to open the scoring before half-time and Omer Toprak's late own goal ensured there would be no way back.
