Founded in 1899 by a group of Swiss, English and Catalan footballers led by Joan Gamper, the club has become a symbol of Catalan culture and Catalanism, hence the motto "Més que un club" ("More than a club"). Unlike many other football clubs, the supporters own and operate Barcelona. It is the second most valuable sports team in the world, worth $3.56 billion, and the world's third richest football club in terms of revenue, with an annual turnover of €648.3 million.[2][3] The official Barcelona anthem is the "Cant del Barça", written by Jaume Picas and Josep Maria Espinàs.[4]
