Anyways, based on what i saw of Dudas, he is more of a creative midfielder than a striker. He did do a lot of wing play, as someone mentioned here already and he seems to really have an eye for the unexpected and spectacular pass.
He seems to have impeccable techinque and burning desire to win. He was the one willing the whole team on when things didn't go right and seemed the most frustrated by failing to reach the semifinals.
He might have some catching-up to do physically, as most Hungarian players seem to do. (Consider Gera and his injuries). The good news is that he is very young, so all that can yet be fixed. He doesn't seem to be too slight of build, though.
His pace, i'm not sure about, it was difficult to judge against the competition at the U17s. I certainly don't remember him blasting past anybody, but I reckon he has at least decent pace if he could play on the wing.
