Unai Expósito

Born in Barakaldo, Biscay, Expósito graduated from Lezama, Athletic Bilbao's renowned youth academy, and made his debut for the first team during the 1999–2000 campaign while also appearing for the reserve side. From 2003 to 2005, after a season-long loan with CD Numancia in the Segunda División, he represented neighbours CA Osasuna also in La Liga. In July 2005, Expósito returned to Athletic as a full member of the main squad but, having taken part in just four games in 2007–08, he signed for Hércules CF in the second tier. He joined another club in that league at the end of a sole season, FC Cartagena who had just promoted. Expósito returned to Numancia on 27 June 2011, agreeing to a two-year contract.

Expósito was the nephew of Iosu Expósito, guitarist and singer of Spanish punk rock band Eskorbuto.
