bundesliga.com rounds up the post-match reaction to Sunday's match-up...
Admir Mehmedi: We have to play like that every week and show our fighting spirit. We played well over the course of the game and everyone was willing to help out at the back.
Sascha Riether: We wanted to build on the DFB Cup win [over TSV 1860 Munich]. We succeeded: We played well and deserved to win.
1. FC Köln
Matthias Lehmann: We didn't play well. We made a lot of errors - that goes for me as well. I didn't settle into the game. We didn't get anything out of it today, but that won't keep us down.
Kevin Wimmer: We weren't smart enough. Our banks of four didn't provide enough movement. It's an annoying result. We were punished for our mistakes.
