Athletic Bilbao defender Andoni Iraola has called on his side to "go for" Espanyol in Wednesday's Copa del Rey semi-final second leg.
The tie is currently on a knife edge after the two sides played out a 1-1 draw in the first leg last month.
Espanyol will start as the favourites on their own patch, but Iraola is confident that the Basque outfit can upset the hosts.
"Espanyol have got things all in order at the moment. They don't give up much at the back and up front, they have players who can make the difference in these games," Iraola is quoted as saying by Inside Spanish Football.
"We'll have to keep a watchful eye on them, but also while knowing that we need a goal and we have to go for them from the beginning."
The winner will play either Barcelona or Villarreal in the final.
