my bad, their system is much worse
In 2004, the honor of “Verdiente Meistervereine” (roughly “distinguished champion clubs”) was introduced, following a custom first practised by the Italian Football Federation,{cn} to recognize sides that have won multiple championships or other honours by the display of gold stars on their team badges and jerseys. Each country's usage is unique and in Germany the practice is to award one star for three titles, two stars for five titles, three stars for ten titles, and four stars for twenty titles.
The former East German side Berliner FC Dynamo laid claim to the three stars of a ten-time champion. They petitioned the league to have their DDR-Oberliga titles recognized, but received no reply. Dynamo eventually took matters into their own hands and emblazoned their jerseys with three stars. This caused some debate given what may be the tainted nature of their championships under the patronage of East Germany's secret police, the Stasi. The issue also affects other former East German and pre-Bundesliga champions. In November 2005, the DFB allowed all former champions to display a single star inscribed with the number of titles, including all German men's titles since 1903, women's titles since 1974 and East German titles.[5]
The DFB format only applies to teams playing below the Bundesliga (the top two divisions), since there the DFL conventions remain in force. BFC Dynamo Berlin have not followed this guideline and continue to wear three stars, rather than a single star inscribed with the number 10. Greuther Fürth unofficially display three (silver) stars for pre-war titles in spite of being in the Bundesliga second division.
