Spain has a great history of soccer, arguably only beaten by England and Italy in terms of football heritage. Names of players like Raúl, Puyol or Casillas constantly come up in sports press around the world.
Soccer in Spain is inexpensive with tickets available at times for less than 20€ if you're a member of the Club. If you have the chance to see a game in which Real Madrid, Barcelona, Sevilla or Athletic de Bilbao are playing, you'll definitely be in for an exceptional night of soccer.
