Not sure... Bayern are a possesion team, a bit like us, at least from what I hear. I can't see anyone beating us at our own game. While Dortmund and RM are more counter-attacking teams.
Dortmund were shit against Malaga, but I don't expect them to be that bad in the semis, just like how I'm pretty sure we won't be as bad as we were today.
Definitely don't want to face Real Madrid though. IMO, at our best, we can beat them, but they still have the best chance of knocking us out.
