Real Mallorca assistant coach Dani Pendin has hailed the potential of Takefusa Kubo.
The teenage Japan international has spent this season on-loan at Mallorca from Real Madrid.
Pendin declared: "He is a young boy and a very good footballer.
"He still has to learn a lot, but today he is a much better player than when he arrived. We worked a lot with him and also is very intelligent.
"He is a boy of 19 years, but has a head like 30.
"He's very polite, respectful and pays a lot of attention every time the coach speaks."
He added: "As a left-hander he has the privilege and has a gift that God gave him, that quality he has to play and to control. He also has a lot of speed, whether in short or long, and a very good strike."
