The club's president has urged the side to stick together on the back of a difficult week at the Santiago Bernabeu.
That loss means the club now has just one realistic hope of lifting a trophy this season, with Los Blancos set to face city rival Atletico Madrid on May 17th in the Copa del Rey final having all but surrendered its Liga crown to Barcelona.
And with controversy surrounding coach Jose Mourinho following his comments regarding Iker Casillas and yet more rumors linking the Portuguese manager with the Madrid exit door, Perez is determined to ensure the club's season does not end in turmoil.
“We have to be united for our people and fans, and our players will do it,” he said at the fifth edition of the Real Madrid Chair Research Grants. “Real Madrid is driven by the strength, energy and passion of the fans. We always owe it them.
“Soon we will have a new challenge to focus on - the Copa del Rey final.”
The club president then added his desire to see "professional leaders in sport" at the "21st century Real Madrid" as he bids for senior figures to steady the ship once more.
