Athletic Bilbao will meet Barcelona in the Copa del Rey final after victory over Espanyol.

With the scores 1-1 after the first leg, the visitors took the lead after 13 minutes as the home defence failed to clear Oscar de Marcos' cross and Aritz Aduriz picked the ball up and slotted past a diving Pau into the bottom corner for his 15th goal this season.

Bilbao went 2-0 up just before the break as Xabier Etxeita headed home from Andoni Iraola's corner to complete a 3-1 aggregate victory and set up a final clash with Luis Enrique's men.
