Altonaer FC von 1893
"Altona" is one of Germany's oldest football clubs: they were part of the Altona-Hamburg football league formed in 1894, as well as one of the founding clubs of the German Football Association (Deutscher Fussball Bund or German Football Association) at Leipzig in 1900. In 1903 at their home ground, they hosted the first-ever German national championship final played between "VfB Leipzig" and "DFC Prague". The match was refereed by "AFC" player Franz Behr, who also served as the vice-chairman of the newly formed DFB until 1904. The club rescued the match by providing a new ball when the original one proved to be unsuitable for play. The hosts of the country's first title match never won or even played in a national final, being able to advance only as far as the semi-finals in 1903 and 1909, and the quarter-finals in 1914.
FC Mulhouse
Mulhouse was founded under the name Fussball-Club Mülhausen in what was then Mülhausen, Alsace-Lorraine in Germany. The club's location has been dependent on the control of the Alsace region between France and Germany. Mulhouse has played in French football since the re-acquisition of the region after World War II and is the second-oldest football club in France after Le Havre AC. The club has achieved minimal honours in its history having spent most of its existence playing in the amateur divisions of France. However, Mulhouse have spent seven seasons in Ligue 1 and 27 seasons in Ligue 2. The club's highest honour to date in France was winning the Division d'Honneur in 1928. Regionally, Mulhouse has won the Alsace Division d'Honneur seven times. During the club's stint in Germany, it won the Gauliga Elsaß three times.
