Osasuna climbed off the bottom of La Liga courtesy of a 0-0 draw away to Real Sociedad on Friday.
The visitors from Pamplona almost took the lead within 60 seconds of kick-off at Estadio Anoeta, Nano connecting with a corner and forcing Sociedad goalkeeper Claudio Bravo into action.
Diego Ifran went close for the hosts in the 11th minute, heading a Carlos Vela delivery over the crossbar.
Sociedad threatened again shortly before half-time, with Antoine Griezmann sending a shot just wide of the upright.
Vela acted as provider for Ifran just after the hour-mark, but the Uruguay forward failed to hit the target with another header.
On 85 minutes Sociedad briefly appeared to have won it, when Griezmann put the ball in the back of the net, only for the strike to be correctly ruled out for offside.
The result sees Osasuna go 19th at the expense of Espanyol, who are at home to Getafe on Sunday.
Sociedad meanwhile are ninth, two points outside the Europa League qualification places.
