For Hamburger SV it was the first national championship, having played in the inconclusive 1922 final and declined the championship. Hamburg would make another appearance in the final in the following season but lose to 1. FC Nürnberg, followed by another championship in 1928, won against another club from Berlin, Hertha BSC.
