Barcelona coach Ernesto Valverde says they're confident overcoming Espanyol's lead in their Copa del Rey tie.
Espanyol's 1-0 victory in the first leg of their Copa del Rey tie has left the Blaugrana needing a comeback in front of their own fans at the Camo Nou.
Valverde admitted that the situation is a tough one, although he pointed out that his side have already come from behind in a few games this season.
"It is a difficult situation, but this won't be the first time that we have to head into a situation in which we're behind on the scoreboard," he said at Wednesday's press conference.
"It is a knockout tie and we are behind, but we're playing at home and we hope our fans help us out.
"These are the matches that motivate you.
"The prize is sweet and we will try to make it to the semi-final."
