Barcelona president Sandro Rosell admits there's one player at Real Madrid he'd like to sign. But he refuses to identify the potential transfer target.

"There is one Real Madrid player I have liked for many years," he told Punto Radio. "But I'm not going to say who it is because I would be creating a circus.

"Madrid have some great players and of course there is one I would like to sign. Is it [Iker] Casillas? I'm not giving away any clues."
