Futebol Clube do Porto, commonly known as FC Porto or simply Porto, is a Portuguese sports club based in Porto. It is best known for the professional football team playing in the Primeira Liga, the top flight of Portuguese football. <br /> <br />Founded on 28 September 1893, Porto is one of the "Big Three" (Portuguese: Os Três Grandes) teams in Portugal – together with Lisbon-based rivals Benfica and Sporting CP – that have appeared in every season of the Primeira Liga since its establishment in 1934. They are nicknamed Dragões (Dragons), for the mythical creature atop the club's crest, and Azuis e brancos (Blue-and-whites), for the shirt colours. The club supporters are called Portistas. Since 2003, Porto have played their home matches at the Estádio do Dragão, which replaced the previous 52-year-old ground, the Estádio das Antas.
