Koren is an attacking central midfielder, ask any West Brom fan and they'll tell you this. His best games for them were playing in that position he left because he kept getting put on the wing, now circumstances have seen him used for the majority of games on the wing for us. He's just got on with it, as at a guess, he knows NP is building his own squad and we didn't have any real wingers.
Now we have the players to put out on the wing (Brady/Pusic/Stewart/Dudgeon) Koren can be used in the middle or behind Fryatt.
