Iker Muniain was born in the Basque city of Pamplona and attended local youth academy Txantrea before joining Lezama in 2004 when he was just 12 years old. From the moment he arrived in Bilbao it was clear that the winger had something magical. He made his first team debut on 30 July, 2009 in a Europa League qualifying match against BSC Young Boys. On his debut he became the youngest player in club history to represent the first team at only 16 years, 7 months, and 11 days old. Muniain instantly became a fixture in the starting lineup and has since gone on to feature in nearly 400 games and has been named a team Captain.
Iker Muniain is under contract through 2024 and his deal does not contain a release clause.
