Barcelona and Real Madrid avoided each other in the draw for the Copa del Rey quarter-finals on Friday.
Quique Setien's men, who beat Leganes 5-0 in Thursday's round of 16 tie, were pitted against Athletic Club in the last eight, with the game taking place at San Mames next week.
Former Athletic defender Andoni Goikoetxea, the club's representative at the draw, feels their home advantage could be key.
He said: "I like the draw. I wanted it to be at San Mames. It's a very difficult draw, we'll see what happens but it'll be a party.
