Juan Legarreta

He began his senior career at the age of 16 playing for Irún Sporting Club, making his debut against an unknown Belgian team and scoring three goals. His best years came with Real Unión - a union of Sporting Club de Irún with Racing Club de Irún - playing a vital role in the club's triumph at the 1918 Copa del Rey Final as he scored both goals of a 2-0 win over Madrid FC (now known as Real Madrid). He then went to Chile to play for both Club Ibérico Balompié and Unión Deportiva Española.

In 1915, aged 18, he represented the Northern Basque Country national team, a squad made-up of Basque players. He was part of the team that won the first edition of the Prince of Asturias Cup in 1915, an inter-regional competition organized by the RFEF. He scored the only goal of a 1–0 win over Catalonia. He also represented Chile, playing two friendly matches against Argentina on 25 September and 2 October 1921.
