In its original format, the winners were assured a place in the 2020–21 UEFA Europa League group stage, however this place was forfeited under the extraordinary circumstances of the COVID-19 pandemic in Spain, with the two finalists (Athletic Bilbao and Real Sociedad) opting instead to delay the date of the postponed match.
Real Sociedad won the final 1–0 against Basque rivals Athletic Bilbao, achieving their second Copa del Rey title[1][2] (in 1909 it was won by its forerunner, Club Ciclista de San Sebastián), ending a 34-year trophy drought since 1987.
