Atletico chief Miguel Angel Gil Marin rejected claims that Real Madrid wanted the player by revealing that Juve have come forward.
"The only side which I have talked to are Juventus. I have been contacted by the Italian club, they have sent me a letter in which they have asked to negotiate for the player.
"Last Monday we received a fax from the Bianconeri. They showed their interest, but we will only let Aguero go for 45m - and not a euro less."
