Portuguese Super Liga

The Primeira Liga , also known as Liga NOS for sponsorship reasons, is the top professional association football division of the Portuguese football league system. It is organized and supervised by the Liga Portuguesa de Futebol Profissional, also known as Liga Portugal. Founded in 1934 as an experimental league called Campeonato da Liga da Primeira Divisão, it was officialised in 1938 and named Campeonato Nacional da Primeira Divisão until 1999, when it was renamed Primeira Liga. Over 70 teams have competed in the Primeira Liga, but only five have been crowned champions. Among them, the Big Three – S.L. Benfica (37 titles), FC Porto (28) and Sporting CP (18) – have won all but two Primeira Liga titles; the other winners are Belenenses (1945–46) and Boavista (2000–01).
