Oihan Sancet was born in the Basque city of Pamplona where he joined local club Osasuna as a child. After becoming one of the jewels of the academy, the midfielder decided to leave to sign with Lezama in 2015. Sancet really made a name for himself while playing with the Juvenil A team in the 2017/2018 season where he stood out as one of the best players in the country and was called up to the Spain U18s. Still a teenager, Sancet was invited to spend the preseason training with Athletic Club’s first team before joining Bilbao Athletic. He suffered a torn ACL early in the second game of the season and returned to the field before the end of the campaign. Sancet made his first team debut on 16 August, 2019 in a 1-0 win over Barcelona at San Mamés.
Oihan Sancet is under contract through 2024 with an undisclosed release clause.
