In 2003, the Bundesliga began to set up championship stars for championship teams. One star represents 3 league championships, two stars represent 5 times, three stars represent 10 times, and four stars represent 20 times. Bayern Munich Football Club has won 29 German football top flight championships, so there are four stars on the team jersey.

Dortmund has eight top league titles and now has two stars embroidered on them.

Extended information:

The championship star is one or more star-shaped marks displayed near the jersey team emblem of some national football teams and football clubs to symbolize that the team has won important awards. Sometimes it's just a unilateral action by the team, without some kind of privilege or approval from any regulatory agency. Different star standards may be adopted in different countries and competitions.

The championship star originated in Italy. Juventus placed a star above its team emblem for the first time in 1958 to represent their 10th Serie A championship.

The main reason for the five-star Brazil is that the Brazilian men’s national football team has won five World Cup championships. These five championships were won in 1958, 1962, 1970, 1994, and 2002 respectively. That’s why it’s called Five Star Brazil.
