Alfonso Olaso Anabitarte (17 March 1905 - 19 December 1937) was a Spanish footballer who played as a defender for Athletic Madrid.
At Nacional, he stood out for his great defensive performance, which eventually earned him a move to Athletic Madrid in 1926, joining his brother who had been at the club since 1919 and who was by then an established star of the team together with Monchín Triana.
[3] Olaso earned his first and last international cap for the Spain national team on 9 May 1927 in a friendly against Italy in Bologna, which ended in a 0–2 loss.
There are two versions of what he could have happened to him; according to some he bled to death from the wounds he had received; according to others he was executed for his official status by the men of El Campesino.
After the Civil War, the press paid tribute to him on more than one occasion and since the 1950s the Spanish Football Federation decided to launch the Alfonso Olaso award in his memory.
