I've watched a lot of him and for a 19 year old he is exceptional. Although he does still have raw elements to his game. He does sometimes dwell on the ball too long, tries to take too many people on, and by the 70th minute he has ran himself into the ground. He would learn so much playing alongside someone like Casemiro. Someone who could school him in playing the simple passes, keeping the momentum of a move going, conserving energy by holding your position and not running about like Tevez on speed.
I would currently put him in the same bracket of Camavinga, and he went for 27m.
