The Segunda Division minnows from outside Madrid made a name for themselves last season when they stunned illustrious neighbours Real Madrid in the cup over two legs.

However, Joaquin Caparros' Basque outfit ground out a solid 1-0 win away from home tonight to take an edge into the second leg at San Mames.

Midfielder Gurpegi made the difference, beating goalkeeper Raul Moreno in the 55th minute.

Almeria came from 2-0 down to earn a stunning 3-2 win away to Primera rivals Real Sociedad.

An own goal and two strikes in the last 20 minutes from Argentinian Jose Ulloa secured the impressive first-leg victory.

Tonight's other game saw top flight rivals Osasuna and Deportivo La Coruna draw 1-1 in Pamplona.

Juanfran's 68th-minute opener for the home side was cancelled out within two minutes by Saul Fernandez.
