Dealing with a derby, it is always difficult, as Augsburg have been playing well lately and will do everything to get at least one point at our ground.\"We\'ve had trouble against them in the first round, even if we won the game there. In the second round, they have vastly improved and I imagine that tomorrow\'s [Saturday] game will be more complicated.\"Dortmund are also in action on Saturday as they face an away trip to Wolfsburg
