Endika Buján

Buján began playing football with the academy of Barakaldo in 2011, before moving to Danok Bat in 2015 where he finished his development. He returned to Barakaldo in on 23 June 2022 and was promoted to their first team competing in the Tercera Federación. He helped them earn two consecutive promotions from the Tercera Federación to the Primera Federación, with 11 goals in 60 matches. On 1 February 2024, it was announced that Buján would sign with Athletic Bilbao, and he was assigned to their B-team. In October 2024, he suffered a fracture in his back that left him off the field for a couple of months. On 8 February 2025, he debuted with the Athletic senior team as a substitute in a 3–0 La Liga win over Girona (Maroan Sannadi, a new signing and fellow former Barakaldo player, doing likewise).

Buján is a fast, left-footed winger who can play on both sides of the pitch and in the midfield.
