bundesliga.com rounds up the key protagonists' views of the action from Signal Iduna Park...
Nuri Sahin: We didn't play particularly well today. We started well, but then it became hard work for us. The positive thing is that we took three points from the game.
Pierre-Emerick Aubameyang: We knew even during the game that it would get more difficult the longer it went on. But we had a lot of players who were on international duty this week, and some recovering from knocks, who couldn't train properly. We were a bit off the pace today.
Sokratis Papastathopoulos:: We made a few mistakes at the back and gave them too much space at times. But at the end of the day we've won the game and kept a clean sheet, which is the most important thing for us.
Leon Andreasen:: We were brave going forward and we competed well to try and get a point here. It was a really tough game, but I think we deserved something from it, and the Dortmund players even said as much.
Artur Sobiech:: I think that was our best away performance so far. We played well against Dortmund and created chances for ourselves. It's a shame that we couldn't get anything from the game.
Ron-Robert Zieler:: It's really disappointing that we conceded so early on, but the team showed a great reaction. I think back to when we've come here in previous years and collapsed after conceding an early goal, but that didn't happen today.
