Osasuna have moved above Athletic Bilbao in La Liga after a 2-1 win at the Estadio Reyno de Navarra.
The hosts took an early lead in fortunate circumstances as Ander Iturraspe put through his own net after 10 minutes.
Osasuna extended their advantage on 30 minutes thanks to Raul Garcia's header from Francisco Punal's inviting cross.
Fernando Llorente bagged his 14th goal of the season soon after half time to give Bilbao hope.
As the visitors bombarded the opposition goal, Iker Muniain had a chance to salvage a point at the death, but his scuffed effort was clawed away by Andres Fernandez.
