1910 UECF Copa del Rey final
The 1910 Copa del Rey final was the 8th final of the Spanish cup competition, the Copa del Rey. It was one of two rival Cup competitions played in that year due to disagreements between the tournament's reigning champion, Club Ciclista de San Sebastián, and some of the clubs invited.
This was the "unofficial" competition, organised by the UECF, in San Sebastián. Both its winner and that of the rival, the newly created FEF, later Royal Spanish Football Federation in Madrid played two months later, are currently recognised as official by the RFEF.
The final was contested by Athletic Bilbao and Vasconia, and was held at Ondarreta Stadium, San Sebastián on 20 March 1910. Athletic won the trophy for the third time in their history after defeating Vasconia 1–0, with the only goal of the game being scored by Remigio Iza.
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.
