Mikel Jauregizar

Jauregizar began his career with hometown club Bermeo, making a single appearance for their senior team in 2019 at the age of 15. He moved to Athletic Bilbao's youth academy on 1 April 2021. In 2022, he started playing with their third team Basconia. He was promoted to the second team, Bilbao Athletic, for the 2023–24 season. In October 2023, he began training with the senior Athletic Bilbao squad after injuries to some of their regulars. On 20 November 2023, he extended his contract with the club until 2028. Jauregizar made his professional debut for Athletic Bilbao as a substitute (replacing his friend and fellow former Bermeo player Unai Gómez) in a 3–0 Copa del Rey win over Cayón on 7 December 2023. Nine days later, he again came off the bench for his debut in La Liga, a 2–0 home victory over Atlético Madrid. After establishing himself as an important member of the team in 2024–25, he was assigned the '18' squad number, only worn by significant figures Bittor Alkiza, Carlos Gurpegui and the retiring Óscar de Marcos in the previous three decades.

Jaurezigar was called up to the Basque Country national team for a friendly match against Palestine on 15 November 2025.
