C'mon he wasn't punching Koller, he was shoving him away a little and Koller fell really easily. He was apparently provoking Volkan, something that is banworthy as we know since WC06. Fact is, his shove was in no way more violent than Schweinsteiger's, I think that the latter was alot more harmful, so why is Volkan getting a two match ban and Schweinsteiger only one match?
