Athletic Bilbao have thrashed Osasuna in their La Liga match this afternoon.
Bilbao took the lead with just three minutes played when Markel Susaeta received the ball on the edge of the box and hammered a shot into the top corner.
However, Osasuna came back quickly and were level through Emiliano Armenteros's free kick.
The visitors went back in front with just 16 minutes on the clock. Andres Fernandez was guilty of poor goalkeeping and Aritz Aduriz bundled the ball in from close range.
Iker Muniain took too long to shoot and was closed down as the away side searched for a third goal before the break.
Moreno Mikel Rico then curled wide early in the second half and Susaeta fired a free kick just wide of the post. The home side had two decent chances to equalise, but Damia and Marc Bertran missed the target when well placed.
Aduriz then got his second of the game with just over an hour played as he converted a deep cross at the far post.
However, Bilbao's job was made easy when Javi Arribas was given his marching orders for a late challenge on Susaeta, as Ibai Gomez and Kike Sola added late goals for a convincing win.
