Clubs were also allowed to indicate the number of championships they have won in the center of the star. The regulation only applies to clubs playing in a league under the DFB umbrella. It does not apply to clubs playing in the 2. Bundesliga and Bundesliga, which are organized by the DFL. The new regulation meant that BFC Dynamo was finally allowed to emblazon its shirts with a championship star. The regulation also affected other former East German teams including Dynamo Dresden with its eight titles, 1. FC Frankfurt with its six titles and Magdeburg with its three titles in the Oberliga.
