CA Osasuna is a professional football club based in Pamplona, Navarre, and the phrase nunca se rinde, meaning never surrender, has become closely tied to the club's supporter identity and fighting reputation. Fans sing it at El Sadar and share it in matchday videos, goal compilations and social media edits, where it signals loyalty through difficult results rather than only celebrating victories. Its spread online has turned a stadium chant into a shorthand for resilience for Osasuna supporters, keeping it in use long after individual matches end.
