Pierre-Emerick Aubameyang had good reason to be smiling after Borussia Dortmund's 2-0 win over FC Ingolstadt 04.

His late brace earned the Westphalians another three points, and took him on to 20 goals for the season. His celebration? The obligatory somersault, of course, even if not everybody is so keen on him doing that.

Dortmund fans need not be concerned, though, as the Gabon forward is a dab hand at a celebration he hopes to show many more times this season, as he explained after getting his feet back firmly on the ground in the catacombs of the Signal Iduna Park.

Question: Pierre-Emerick Aubameyang, quite a lot of people are worried that you might pick up an injury when you celebrate like that…

Pierre-Emerick Aubameyang: (smiles) They don't need to worry! When you score a goal, and when it's a decisive one, then your emotions just take over. I don't really think about it, I just jump. No worries, though, I do take good care.

Question: With your two goals against Ingolstadt, you are continuing to chase the Bundesliga single-season record of Gerd Müller. Can you match his 40 goals this season?

Aubameyang: That would mean scoring another 20 goals! That's a lot, but you can never tell what will happen in football. Let's see!

Question: You have nevertheless reached the 20-goal mark and therefore won your bet with Thomas Tuchel. Can you now tell us what was at stake?

Aubameyang: (smiles) You're right, I've reached my aim [for the season], but I've not yet reached that of the coach. We'll have to see how things progress.

Question: Are you relieved that you've scored again, after you didn't get a goal last week against Mönchengladbach.

Aubameyang: You don't always score and that was the case last weekend for me. What mattered was I kept my focus and fortunately I didn't have to wait long to score again.

Question: You've won, scored two goals and moved further ahead of Robert Lewandowski at the top of the goalscoring chart. Does it get any better?

Aubameyang: I'm really not interested at all whether Robert Lewandowski is ahead of me or behind me in the scoring chart. The most important thing is that I've been able to score these goals for the team and help them win these games, then we can add it all up at the end.

Question: It was a hard-earned win today, though. Why do you think you struggled so much for 70 minutes against Ingolstadt?

Aubameyang: Ingolstadt were very well organised and played a very well structured game. We had to remain patient, which we also managed to do. Maybe we could have and should have shown a bit more of our footballing ability, which we weren't able to do at all in the first half. But we got better in the second half and were able to win the game in the end.

Question: Were the heavy pitch and the wind also a problem?

Aubameyang: Yes, they also played a bit of a role. Things were not quite right overall and maybe we just wanted to do too much in our first home game of the second half of the season and show our fans something special, and that actually appeared to hamper us.

Question: Marco Reus and Ilkay Gündogan missed the game due to illness. Was that also a problem?

Aubameyang: Of course, when you lack two such amazing players, any team would suffer. But the 11 men we had on the field worked well and did everything to win the match.
