Arsenal boss Wenger excited by Nordtveit potential
Wenger is aware that Nordtveit is not the 'finished article' but in certain areas he is well ahead of schedule.
"What I liked in this boy is his intelligence and his mental strength," Wenger told arsenal.com. "He is very mature. In fact I have rarely seen a boy of his age so mature.
"Physically we need to get him up to the Premiership level, at the moment he is a bit behind. But technically and tactically he is already there. He is an intelligent boy with good vision. He has a good pass out from the back and he is strong too.
"I hope that he can develop well."
