Werder Bremen are perfect so far at home, but they face a stern challenge with defending champions Borussia Dortmund coming to the Weserstadion. Dortmund are well behind Bremen in the table, but some of their performances of late have been superb, and everyone knows what they're capable of when clicking. Bremen aren't exactly pushovers either, however - this should be a superb test of each team's credentials to challenge early leaders Bayern Munich.
