I've been in Germany for the weekend and saw Werder v Wolfsburg. Having seen the highlights of the Hoffenheim game last night they looked okay, although Schalke did have 2 men sent off. The first was quite funny as the guy went properly mental with the ref and almost decked him. Bayern were a bit unlucky to conceed in the 4th minute of injury time, especially as Jens Lehman went up for the corner and decked the keeper twice in the build up.
The reaction to their team seemed to be a bit like the one Gretna had which at the moment is the fairytale story, but i imagine that may turn if they become a regular fixture. There is already apparently some antogonism about playing in someone elses stadium.
