Jon Irazustabarrena

Born in Usurbil, Gipuzkoa, Txusta graduated from Real Sociedad's youth system, and made his debut with the reserves in the 2003–04 season, in the Segunda División B. In 2005, he signed for neighbouring SD Beasain from Tercera División. Txusta was recalled by Sanse in summer 2007, but after being sparingly used he returned to Beasain in July 2008. In August 2009 he joined another reserve team, SD Eibar B also in the fourth division; he remained in that tier the following three years, representing CD Lagun Onak and Beasain. On 29 January 2013, Txusta signed with division three club SD Eibar. He made four appearances during the campaign, as they returned to Segunda División after a four-year absence. On 31 May 2014, as the Basque side were already promoted to La Liga, the 28-year-old Txusta played his first match as a professional, starting in a 1–0 home win against CD Lugo. Roughly a month later, he renewed his contract for a further year.

Txusta signed for third-tier Real Unión in July 2015, after being released by Eibar. On 6 July 2016, he joined Barakaldo CF in the same league. On 29 May 2018, Txusta returned to Unión, agreeing to a two-year deal.
