Speaking to ESPN, Brito did acknowledge a meeting with Real Madrid but insisted that Mastantuono was not discussed.
"There've been no negotiations with Real Madrid for Franco Mastantuono, I can guarantee that," he said. "Not with Florentino Perez, or anybody else. There was a meeting for other reasons. The player is calm, and very happy at River. We think there's no need to hurry. He's still developing, he's 17 years old. Neither the player nor we are in a hurry for him to leave."
