Valencia midfielder David Albelda admits their confidence is at rock-bottom after Saturday's 3-0 home defeat by Barcelona.
Albelda said: "It's a mental problem, players do not want the ball and there are no signs of improvement. You think everything is going wrong. Playing at home and believing that nothing can be done to stop another defeat is very difficult to cope with.
"It's difficult to give the fans a message of encouragement. They behaved well towards us. This is a time to show pride and character."
