The 1917 Copa del Rey Final was the 17th final of the Spanish cup competition, the Copa del Rey. The final was played at Camp de la Indústria in Barcelona on 13 May 1917. The match ended without goals after twenty minutes of extra-time. The replay match was played two days later, in the same venue with the same referee. The match ended 1–1, and the teams decided to play twenty minutes of extra time. Neither team scored a goal in that time, so they decided to play another twenty minutes of extra time. Three minutes in the second period of extra time, Ricardo Álvarez scored for Madrid FC, thus sealing the fifth title for Madrid.[1] [2]
