Ivan Campo says Takefusa Kubo needs to step things up at Real Mallorca.
Like the Japanese teen, Campo played for both Mallorca and Real Madrid.
He told Marca: "He is not at his best level, but it is normal because he is a very young boy who has to get used to it. He has no experience in our country at this football level and must be patient.
"He must learn to move. He is a great player but he still has a lot to learn and room for improvement. If in Madrid they said that it is best that they should be transferred to a LaLiga team rather than stay in Castilla, for example, they saw it very clearly. I think it's a good idea to be in Mallorca, although things are not going perfect for now."
