Real Unión beat Arenas Club de Getxo 1–0[1][2] and won their third and last title[3][4] (fourth title counting the trophy won by Racing de Irun in 1913).
[2] The Irundarras, who had two great figures of the time in their team, such as Gamborenea and René Petit, the latter as an offensive reference, beat Sporting de Gijón in the quarter-finals and then in the semifinal they eliminated Real Madrid with a 2–0 win, courtesy of Gamborenea and Echeveste.
[5] On the other hand, Arenas had eliminated Celta de Vigo and FC Barcelona in a single-leg semi-final.
The game was tight and René Petit had a golden chance from 12 yards, but he failed to convert a penalty that would have done justice to Unión.
[7] The game thus ended with a goalless draw in its 90 regulation minutes, which forced extra time, where Irundarras still managed to find when Echeveste, after receiving a pass from Villaverde, scored the only goal of the match with just three minutes to go.
