In association football, some national and club sides include one or more stars as part of (or beside) the crest on their shirt to represent important trophies that the team has previously won. According to various football history sources, the first team to adopt a star was Juventus in Italy, who added a star above their crest in 1958 to represent their tenth Serie A title. This was an extension of the convention by which the reigning champions are entitled to display the scudetto on their shirts for the following season. The star was later formally adopted as a symbol for ten titles
