Espanyol midfielder David Lopez says that "Barcelona can be beaten" ahead of the Copa del Rey game on Wednesday at Cornella.
"We will go out to win, above all at home. I hope that as many people as possible come to support," he said.
"We have to concentrate, maintain the intensity for 90 minutes. Yesterday Real Sociedad had a good first half but lowered their intensity a bit. Barcelona are capable of coming back."
The Espanyol player says not losing for four games in a row "gives us more confidence to go through".
