Iñigo Larrainzar Santamaría (born 5 June 1971) is a Spanish retired footballer who played mainly as a right-back.
[1][2] A product of hometown CA Osasuna's youth academy and reserve team, where he played alongside future Athletic Bilbao teammate José Mari, Pamplona-born Larrainzar made his first-team – and La Liga – debut on 21 March 1990 in a 1–0 away loss to Rayo Vallecano, and was definitely promoted to the main squad for the following season; aged 19, he was instrumental, as was brother Domingo, in helping the Navarrese side to finish fourth and qualify for the UEFA Cup.
[3] In the summer of 1993, Athletic Bilbao paid 200 million pesetas to acquire Larrainzar's services, then the second-highest figure by the club, and he was an undisputed starter in the following campaigns.
[2] In 1997–98, alongside youth graduate Aitor Larrazábal who played on the opposite flank, he featured in 34 matches and scored two goals to help the Basques to a runner-up place, with direct qualification for the UEFA Champions League.
After some years battling for first-choice status with younger Jesús María Lacruz, who also represented Osasuna (although they did not coincide),[4] and also dealing with injuries,[5][6] Larraínzar moved south for Córdoba CF in the Segunda División,[7] where he played a further two seasons.
