Im from Porto and i think this is a little bit overrated.
Yes, he can shoot and very well and has an incredible combination of power and speed, but he has an extremly low football I.Q. and loses temper and concentration so easily. That can be trained, but he still has times that behaves like a kid.
When things go wrong he need a ball to himself, that needs to be corrected. He can spend 89 minutes losing balls and complaining with referees and then scores one great goal.
40 million and it would be a very good sell.
Not de 100 that Pinto da Costa wants, although i believe he can get the transfer done by values above 50
