La Liga
In April 1927 Alvaro Trejo, a director at Arenas Club de Getxo, first proposed the idea of a national league in Spain. After much debate about the size of the league and who would take part, the RFEF eventually agreed on the ten teams who would form the first Primera Division in 1928. FC Barcelona, Real Madrid, Athletic Bilbao, Real Sociedad, Arenas Club de Getxo and Real Unión were all selected as previous winners of the Copa del Rey. Athletic Madrid, RCD Español and CE Europa qualified as Copa del Rey runners-up and Racing Santander qualified through a knock-out competition against Sevilla FC. Only three of the founding clubs, Real Madrid, FC Barcelona and Athletic Bilbao, have never been relegated from the Primera Division; six other clubs have never been below the top two tiers: Sevilla FC, Real Sociedad, Sporting de Gijon, Valencia CF, RCD Espanyol, and Atlético Madrid.
