1910 Copa del Rey
The Copa del Rey 1910 comprised two different competitions held the same year.
Due to disagreements between the reigning champion of the tournament, Club Ciclista de San Sebastián, and some of the clubs invited, in 1910 two parallel competitions were held: an "official", organized by the newly created FEF later Royal Spanish Football Federation, in Madrid and an "unofficial", organized by the UECF, in San Sebastián. Both are currently recognized as official by the RFEF.
Copa UECF (Unión Española de Clubes de Fútbol)
The competition started on 19 March 1910, and concluded on 21 March 1910, with the last group stage match. Athletic Bilbao won the tournament for the third time. The tournament is believed to have been the first time Athletic Bilbao wore what became their regular red-and-white striped jersey, having recently imported the first set of kit from England.Group stage
