Iñigo Córdoba was born in Bilbao to a family that were as big Athletic fans as anyone could ever be. He joined Lezama in 2009 when he was just 12 years old, and his two brothers attended the academy as well. At a young age he stood out for his work ethic and joy and really began to blossom when he joined feeder club CD Basconia. After two seasons at Bilbao Athletic he was promoted to the first team in the summer of 2017 and made his debut on 20 August, 2017 in a scoreless draw against Getafe. In just his first season with the senior side Córdoba he quickly endeared himself to the fans at the San Mamés and looks to be a bright player for the future.
Iñigo Córdoba is under contract through 2022 and his deal contains a €30 million release clause.
