Honestly, I couldn't watch. I heard from a friend that he played well, but as a team 1860 were not quite up to snuff. Düsseldorf is an extremely good side. They're probably capable of holding their own in the Bundesliga, so it should be no surprise that they outclassed 1860 Munich today.
Düsseldorf are rather a typical case of "lots of good BL2 players, good chances to get promoted, but absolutely no chance to stay in BL1". The fact that Sascha Rösler is their star player already tells the whole story.
I don't know, I think they're significantly better than Augsburg this year. I'm not saying that Düsseldorf would do well in the Bundesliga, I said "hold their own," which to me means that they wouldn't get dominated.
