Question: Ilkay Gündogan, congratulations on the win. What's your take on it?
Ilkay Gündogan: It's a great feeling to win away from home against such a strong side. We all played brilliantly and can be very proud today. More than anything, the way we played gives us confidence for the coming weeks.
Question: How would you describe the course of the game?
Gündogan: We had to deal with some dangerous situations in the first half, including a header that hit the bar. Also, after they scored to make it 2-1, we were a little unsteady for a while, but that comes with the territory in games like this. We dealt with the difficulties, and in the end, fully deserved the 3-1 win.
Question: And now the advantage over your nearest pursuers is even greater.
Gündogan: We know that our rivals dropped points, that's why it was so important for us to win and increase the gap today. We're looking ahead as well as over our shoulders, and we hope that we at least finish the season in second place.
Question: Did the third goal come at just the right time - in the middle of a good spell for Gladbach?
Gündogan: They were playing with even more courage going forward after they pulled a goal back, and we really had to pull together at the back. I'm happy I was able to get the goal to decide the game. Gladbach have too much quality - you can't stay on top for the entire game against them. We did a good job and we didn't slip up.
Question: At the recent winter training camp, you said you wanted to score more. Was that the start of something today? It looked like you didn't fully connect with the ball.
Gündogan: If I'd have connected with it fully, it wouldn't have gone in (laughs). It wasn't easy because the ball cut inside. It worked out well because I was pretty much unmarked in the box.
Question: Marco Reus opened the scoring once again. Why does he score the first goal so often?
Gündogan: Good question. We're always looking for him in his area of the pitch because he's such a threat from that position. Marco scored another very important goal for us today, after passing up some other decent opportunities. That shows the qualities he has.
Question: As an outsider, the way Dortmund are playing looks very good - the combination play looks second nature. How's it for you as a player?
Gündogan: It's down to a lot of training and hard work, but obviously it's even more fun when you're successful. We want to continue in the same vein, so that we come out on top in our upcoming games.
