Osasuna remain in relegation trouble in La Liga having fallen to a 2-0 defeat at home to Celta Vigo.
Nolito fired the visitors ahead on 20 minutes when he received a pass inside the box, before striking the ball into the roof of the net.
Osasuna came close to drawing level courtesy of Oriol Riera, but his header from close range was well kept out by Sergio Alvarez.
Alvarez was needed once more shortly after, this time to deny Miguel de las Cuevas who looked to find the bottom corner following a rebounded shot inside the box.
The save would prove to be vital as Nolito doubled his tally for the night after 34 minutes, slotting the ball past Andres Fernandez after being picked out be Fabian Orellana.
Los Rojillos looked to pull a goal back but they were unable to find a way through, with Riera coming closest to finding the back of the net when he directed a volley goalwards, only for Alvarez to keep it out once more.
Celta Vigo move up one place to eighth in the La Liga table, while Osasuna remain two-points clear of the drop zone.
