Pique: I only hope the Camp Nou won't throw objects onto the pitch Copa del Rey - Espanyol vs Barcelona Cillessen hit at RCDE Stadium

Barcelona's Copa del Rey clash with Espanyol may be tantalisingly set up by a 1-0 scoreline in favour of the underdogs but Gerard Pique was left unhappy with the way the victor's fans behaved on Wednesday night.

Not only was the Spain defender subject to jeers throughout the game, Jasper Cillessen was hit by an object thrown from the stands.

"The atmosphere is always complex here, it's difficult, but I'm not the one who has to make decisions on that matter," Pique told reporters post-match.

"I only hope that the Camp Nou won't insult anyone or throw objects onto the pitch.

"It doesn't hurt to lose our streak here. The penalty miss may have affected us too much but at the Camp Nou we will have our chances.

"It can be turned around next week."

January 25 will see the teams reconvene in Catalonia for a place in the semi-finals.
