Oier Zarraga

Athletic Bilbao

Born in Getxo, Biscay, Basque Country, Zarraga joined Athletic Bilbao's youth setup in 2009, from hometown side Romo FC. He made his senior debut with the farm team during the 2017–18 season, in Tercera División. Zarraga made his debut with the reserves on 3 February 2019, coming on as a second-half substitute for Gaizka Larrazabal in a 2–1 Segunda División B home win against SD Leioa. Definitely promoted to the B-side in June 2019, he subsequently became a regular starter for the team, playing in all matches of the 2019–20 campaign before the season was curtailed due to the COVID-19 pandemic. In July 2020, Zarraga was called up to the pre-season with the main squad. He made his professional – and La Liga – debut on 18 October, replacing Unai López in a 2–0 home win against Levante UD. In February 2021 he signed a new contract running to summer 2023, also confirming his status as a first team squad member.
