Career
Born in Mendavia, Navarre, Otegui was a California Osasuna youth graduate. In the 2015 summer, he was called up straight to the main squad by manager Enrique Martín for the pre-season, and signed a new five-year deal with the club on 8 August of that year. His Segunda División debut came on 17 October, again from the bench in a 1–0 home success over Albacete Balompié.
