He's been ok, nothing more. First few matches he was struggling to keep up, took too long on the ball and was not very accurate with his passing, which is weird considering this is supposed to be his best attributes. At least that's what he showed playing in the reserves.
Managed to improve his performance in the next games, and started to show some of his passing skill, especially with some nice through balls which eventually led to goals. Last couple of matches he hasn't started, but that's because Ole likes to rotate a bit, especially in midfield which is one of the strongest in Norway, and has lot's of quality players good enough to be starters in the Norwegian premiership.
He needs to improve further if he is to become a hit in Norway, and I believe he will, if he is given some time.
