Real Valladolid coach Sergio Gonzalez admits he knows little about Real Madrid whiz Takefuso Kubo.
Valladolid owner Ronaldo is setting up a loan deal for the teenage Japan international.
Sergio said, "I have no information on that subject and I will not comment on it until I know it.
"I know what has come out in the Press, what I have read, I know that there is an important revolution, but I have no information about it and until it is official or there's true information I will not comment on it."
On Manchester City signing Pedro Porro, formerly of Girona, arriving on-loan, he added: "I have proof, he is one of the alternatives the sports directors manages for the right back."
