bundesliga.com rounds up the post-match chatter from the men in the suits...
Jürgen Klopp (Dortmund): We suffered a real setback early on. That really hurt us as you saw. Today, our aim was to improve our situation, but we failed to do that. Despite this, we'll keep going. I can understand the fans' frustration, after today it's completely acceptable, even though the team tried everything. We're attempting everything but for no reward, breaking that cycle is a really tough challenge. I'm completely responsible.
Thomas Schaaf (Eintracht Frankfurt): You could see that we took plenty of confidence into the game with us, and the early goal only added to that. We played much, much better than in the last few weeks and I'm really pleased with the team's performance.
Jos Luhukay (Hertha Berlin): In the first half, it was really difficult for us. They swapped positions a lot and we couldn't really get into the game or make it tough for them. In the second half, though, it was more equal. Through John Anthony Brooks, we had the best chance to equalise but unfortunately it didn't quite work out.
Pep Guardiola (Bayern): We played well in the first half. In the second half, though, we lost our style. A 1-0 lead is always dangerous and Hertha are very quick on the counter. Perhaps playing in Manchester [against Manchester City FC in the UEFA Champions League] for 70 minutes with only ten men made us a bit tired. I'm pleased with the first half, but we can improve on the second.
Dieter Hecking (Wolfsburg): After two unlucky defeats, the team were outstanding today. We worked extremely well off the ball and that was the key to the win. Robin Knoche [scorer of the only goal] is one of Germany's biggest talents at centre-half. As for Bayern, they're tough to stop, so we're not going to focus on them too much. Even if they do us a favour and slip up, we still have to win our games.
Lucien Favre (Borussia Mönchengladbach): At the moment, we're finding it difficult. After the early goal, we dominated the first half and had 62 per cent of possession. In the second half though, we went long periods without any chances. We gave everything but lacked that little bit of patience.
Roger Schmidt (Bayer Leverkusen): Such a resounding win is completely justified. Köln played extremely defensively, but despite that we kept creating chances. I'm really pleased for Josip Drmic that he managed to score twice.
Peter Stöger (1. FC Köln): It's a little bit tough to accept that the final result came by such a margin. Our defensive structure actually worked quite well, even if that sounds a bit silly after a 5-1 defeat. I wasn't best pleased with the last 15 to 20 minutes, though. Just because we had to take more risks, that doesn't mean we should throw away our system.
Markus Gisdol (Hoffenheim): We were intending to give everything to get a win. The home defeat to Köln hurt us and set us back. In the first half, up until they made it 2-1, we put everything we were trying to do into practice. Then, the reaction after they made it 2-2 was fantastic. We put in a good, concentrated display. We're happy that we've taken three points here against a good opponent.
Tayfun Korkut (Hannover): We scored three goals away from home and yet aren't taking any points back with us. That's not a good day. We conceded two goals from set-pieces, even if one was a rocket of a strike. But, if you score one goal fewer than your opponent, then you don't deserve to win. The game was in our hands at 2-2, and we even had a chance to make it 4-4 at the end. We created plenty of chances, but ultimately, you have to congratulate Hoffenheim on the win.
Christian Streich (Freiburg): We made mistakes in our build-up play, but we started well and just didn't get the goals. After that, we invited Stuttgart to score the goals and it everything that could have gone for them did. We virtually scored four own goals.
Huub Stevens (Stuttgart): We had a little bit of luck in the first half. In the second period though, we played really good football and showed what we're capable of. We won an away game, and you have to be pleased with that. When you win against a direct competitor in the table, then that gives you self-confidence.
