I'm not sure, 4 years ago I think, he and Ebbe Sand shared the first spot. But since then he's been played more in midfield, so he has less goals but more assists.
He's in great form tho, he's scored 9 and had 5 assists in the last 13 matches, he's probably HSV's best player.
Anyways, is it just me or is there a favourism towards HSV by the refs? There were two horrid misstakes against Stuttgart, maybe the refs are "taking care" of HSV because of the whole betting scandal.
