Athletic Bilbao sealed their place in the quarter-finals of the Copa del Rey with a 2-0 win over Osasuna to progress 3-1 on aggregate.
The home side got off to a flying start when Igor Gabilondo fired them in front after just five minutes with a superb effort.
Bilbao doubled their lead on 17 minutes when the unfortunate Josetxo deflected a shot into his own net.
Osasuna wasted a great opportunity to get back into the tie on 64 minutes when Javier Portillo saw his penalty saved by Bilbao keeper Gorka Iraizoz.
Osasuna's misery was compounded in the final minute when Ludovic Delporte was sent off for a dangerous tackle on Markel Susaeta.
Bilbao will meet Sporting Gijon in the last eight.
