The clubs have yet to officially announce a deal has been done for the winger, who is currently at pre-season training, but Getafe coach Michel revealed on Monday that Leon has been sold to Madrid.
Reports suggest the 23-year-old could be sent back on loan to Getafe for the season to ensure he has regular first-team football, and Munoz hopes this will be the case.
"It's logical that the boss wants the best. We're going to try so that that player stays," he said. "He really wants to play and identifies himself a lot with the club. What will happen will be shown in the coming days.
"He's a player who is desired by many clubs. What's important is that now he is training.
"Madrid have their eye on him. We're going to keep calm and what there is to know will be known in the next few days."
