Astrain began coaching by starting and training youth (Cadet) teams at Bidezarra, a Navarrese school.[3] Later, she coached Beti-Onak and the Navarre women's team.[6] She also coached the Spanish women's under-21 team. From 2002 to 2006 she coached for FC Barcelona Femení,[2] which was incorporated as a formal section of the club coincident with her arrival. In the early days of the women's team, it was common for the team to play on fields used as a parking lot on game days for the men's team. Despite these challenges, in 2004 under her leadership the team achieved promotion to the Superliga (the Spanish First Division at the time).[7] In the 2013–14 season she coached FC Levante Las Planas of the First Division.[8] In the 2016–17 season she signed as second coach for Atlético de Madrid, and with them she won the league that season.[9][10]
Roles in USA, 2017-Present
In 2017, Astrain made the jump to the United States, when contacts she had made while coaching at Barcelona academies and camps in the US were looking for someone with a background like hers.[10] She was hired as the technical director of Rise Soccer Club in Houston,[11] a position she held for two seasons. The club had 5,000 players from age 5 to U19, and served as a feeder for local NWSL club Houston Dash.[3] In 2020 she was hired as the coach of FC Bay Area,[12] a WPSL youth development club with Barça roots. Prior to the 2021 season, Astrain signed on as the assistant coach of the Kansas City Current in the NWSL,[13] which had newly relocated from Utah.
While at Rise SC, Astrain had contributed to US Soccer programming in the form of camps and clinics, and as an assistant coach for the U-15 and U-17 girls national teams.[12] This building familiarity led the federation to appoint her as head coach of the USA Under-17 youth national team in November 2021.[14][1] To take the job, she left her role with the KC Current.[15] Astrain led the U-17 team through qualifying,[16] and into the 2022 U-17 World Cup, where they were eliminated in the quarterfinals by Nigeria. She departed from US Soccer in May 2023,[17] citing as reasons the uncertainty in the wake of the departure of USSF Sporting Director Earnie Stewart, and interest in her services as a broadcaster from Telemundo for covering the 2023 FIFA Women's World Cup.[18]
Media career
Astrain has regularly appeared in soccer media, on TV and in print, during the course of her career. In 2015 she provided regular commentary on Barcelona's matches on Barça TV.[6][19]
Starting with Spain's first appearance at the FIFA Women's World Cup in 2015, and continuing through 2021, she held a weekly opinion column in Mundo Deportivo, writing about women's football.[20]
