Perez says it is more important for the Spanish side to have a good relationship with United than signing Cristiano Ronaldo.
“If one day there is a chance of [Ronaldo] playing for Real Madrid, that would be an honour for us,” he told The Times.
“But if I had to choose between the friendship with Manchester United and the signing of Ronaldo, I would choose the friendship.
“Plus, I have never said that Cristiano will arrive in June. That is an arrogant and false statement.”
He continued: “I shall be talking with [United manager Sir Alex] Ferguson and [chief executive] David Gill to build bridges.
“If we sign Kaka from Milan, I can assure you that we will still have a very good relationship with [vice president Adriano] Galliani.”
