He´s very fast, both in running and thinking. That is his main advantage. He has good technical skills, you can´t expect some brazilian finesses, but he can control perfectly the ball even when sprinting. He can create the chances for himself, but not so often for the others. He is not a classic "in-box" striker like van Nistelrooy, scoring even from nothing, Holosko can screw up clear chances quite often. He´s most usefull when playing on counter-attacks. Anyway, as Kajoo said, he´s still a raw diamond, he has the potential to become a complete striker.
