The 1919 Copa del Rey final was an association football match between Arenas Club de Getxo and FC Barcelona on 18 May 1919 at the Martínez Campos stadium in Madrid.

[2] Arenas took an early lead by scoring four goals in the first five minutes and Racing could not come back even though they dominated possession in the second half.

Additionally, the captain felt that the match should have been postponed due to the weather, with both an assistant referee and the representatives of the Central Spanish Federation believing the pitch conditions were not suitable for play.

[6] In the second leg Arenas was much more dominant, demoralizing their captain-less opponents with a 2–0 lead in the first half and handling the heat better in the second to take a 6–1 victory, thus securing a spot in the final.

[8] Barcelona's players had played individually well and Real Sociedad's "very bad form and attack" was unable to take advantage of the eventual winner's weak teamwork.

[8] One week later Barcelona beat Sociedad away 3–1 at the Atotxa Stadium,[10] coming from behind thanks to another hat-trick (this time from Vicente Martínez).

In the first leg in Barcelona, the local team began the match overly confident but were quickly surprised by a dominant performance by Sevilla.

Barcelona responded instantly with an 86th-minute equalizer and followed it up with an 88th-minute winner by club legend Paulino Alcántara, with the Sevillians by now physically exhausted.

[13] Barcelona used a more patient, technical style of play while Arenas relied on a brute-force method of reaching the opponent's goal.

[18] Right-back Reguera and right half-back Agustín Sancho were the most hard-working of the Barcelona players but to no avail against the rapid transitional play and defensive solidity of the winners which proved decisive according to Martin Fernandez.

Viñals managed to find an equalizer for Barcelona off of a deflected shot from Garchitorena,[18] with the team dominating for the rest of the first half.

[21] Viñals gave the Catalans the lead in the early moments of the second half with a cross that Garchitorena passed to Lakatos for the goal.
