Futebol Clube do Porto was founded on 28 September 1893, making it one of Portugal's oldest football clubs alongside Benfica and Sporting CP. After a dormant period, the club was rebuilt in 1906 by António Nicolau d'Almeida and developed into the dominant force in northern Portugal. Porto play at the Estádio do Dragão (Dragon Stadium), opened in 2003 with a capacity of 50,033, replacing the historic Estádio das Antas. The club's blue-and-white colours and dragon emblem (added 1922) are central to its identity.
Porto's defining global moment came in 2003-04 under José Mourinho. The young Mourinho's side — featuring Deco, Ricardo Carvalho, Paulo Ferreira and Costinha — won the UEFA Champions League by defeating Monaco in the final, completing a remarkable double after the 2002-03 UEFA Cup. The triumph turned Mourinho into a global coaching superstar, and Porto's status as Portugal's most-recently-European champion club has yet to be matched. The earlier 1986-87 European Cup, under Artur Jorge against Bayern Munich, plus the 1987 UEFA Super Cup and 1987 Intercontinental Cup, represented an earlier golden era featuring Paulo Futre, Fernando Gomes and Rabah Madjer.
Porto's 30 Primeira Liga titles place them second to Benfica's 38, but their European achievement (two UEFA Champions Leagues, two UEFA Cups, the only Portuguese club besides Benfica with multiple European trophies) makes them Portugal's most internationally-renowned recent power. The Vitalis stadium and Olival training ground have produced João Pedro (now at Brighton), Diogo Jota, Vitinha, Otávio and Hulk-era talents who shaped European football. The fierce O Clássico against Benfica is Portugal's biggest fixture.
