Levante have not won in the league since beating Sevilla 1-0 on December 10, but Iborra is convinced the six-game winless run is just a blip.
"We must show the strength that we are known for, and we can make a good game of it," he said.
"We need to regain the positive feelings and break this streak.
"This is a small bump, but it was not normal how many points we had. It was normal that there would be a downturn at some point. We must move forward. We look forward to the Bernabeu in search of a good result."
