bundesliga.com has the post-match reaction from Cologne...
1. FC Köln
Matthias Lehmann: We created some good opportunities and put a lot of pressure on our opponents, particularly in the second half. Mainz were struggling a little bit and we were desperate to get the goal while remaining solid at the back. We've slipped up on several occasions at home recently, so we tried to attack them in a controlled manner and with a bit more luck we could have won the game.
Dominic Maroh (on his disallowed goal): When a defender scores, they should be given the benefit of the doubt (laughs)! As a promoted side you need that little bit of luck every now and again and unfortunately, we didn't get it today.
Anthony Ujah: A draw is better than a defeat, but we did everything to win the game today. That's football though. Mainz defended very well and we're happy to have picked up a point, but we're not completely satisfied with that outcome.
1. FSV Mainz 05
Johannes Geis: We know the time has come for us to improve our performances and we wanted to get a win away from home today. We're happy to have kept a clean sheet, first and foremost, but we were hoping for that 'lucky punch'. We have to work hard during the winter break and practice putting our opponents under more pressure. We've got to focus on Bayern first of all though [on Matchday 18] and I think everyone's looking forward to that game. The odds are obviously stacked against us against a team like Bayern, but we'll give everything we've got on Friday.
Loris Karius: We wanted three points today, but weren't able to get them unfortunately. It's good that we managed to keep a clean sheet, but you could tell that both teams were waiting for other to make a crucial mistake, which would enable them to get that first goal. Neither team was prepared to take many risks. We've got a bonus game against Bayern now, so we'll have to start picking up points after the winter break.
Yunus Malli: We gave everything and managed to keep a clean sheet. We could have gone 1-0 up in the second half, had Shinji [Okazaki] stuck away his chance. A point isn't really enough in this situation - we were hoping to get more from the game.
Stefan Bell: You could tell both teams wanted to play on the counter-attack and that this was our second game in the space of three days. Both teams looked a little jaded in the last half an hour. I'm happy we've finally kept another clean sheet though, and I think we can be pleased with the point.
