Former Real Madrid coach Bernd Schuster is backing Rafa Benitez for the job.
Benitez announced last week he will leave Napoli.
"Nobody can argue with Rafa. He has a great track record as a coach and in different countries," said Schuster.
"He is definitely good enough for the Real Madrid job. He did a great job at Liverpool, which was a big, demanding club that hadn't won anything for years. That's where he learned the management side of the role, which added to his coaching experience in the dugout. It's important to know both sides of the job."
