Dortmund - Heung Min Son said Bayer 04 Leverkusen "want to challenge" FC Bayern München in the wake of his side's 1-0 victory away to Borussia Dortmund on Sunday.

The 21-year-old hit the only goal of the game - and his third in as many outings at the Signal Iduna Park - to down Jürgen Klopp's men and was understandably in bouyant mood after the final whistle.

Question: Heung Min Son, having led Leverkusen to victory away to title rivals Dortmund, how do you feel?

Heung Min Son: I'm glad to have scored such an important goal. I went into the game hoping to stay cool and enjoy the game and it worked out pretty well. It'll take a while for it to sink in that I've scored against Dortmund again.

Question: You really seem to score whenever you're up against Dortmund. Wouldn't it be best if you faced them week in, week out?

Son: (Laughing) I didn't score against them in my first season. Mind you, I was only 18 years old back then. It's true though, that I tend to have a good feeling whenever I play in Dortmund. I just enjoy playing in front of such a big audience. In the Bundesliga there are so many good sides that you enjoy playing against, and it isn't at all easy to face Dortmund. It always demands a lot of effort and concentration.

Question: You could've even scored twice tonight...

Son: I really should've converted when I had only [goalkeeper Roman] Weidenfeller to beat. I could've rounded him on either side but eventually decided to shoot which proved a mistake. Things would've been easier for us had we gone into the break with a 2-0 lead.

Question: After a difficult start, it seems you've now settled ín Leverkusen...

Son: Things are going pretty well at the moment, but I still need time to settle. Don't forget I only arrived here less than six months ago. I just try to do well in every game.

Question: Can you tell us more about tonight's game plan?

Son: Winning the challenges was key to the success, and that worked out well. We gave our all for this victory. We were fighting for the full 90 minutes.

Question: Things got quite hectic in the second half though, despite the lead...

Son: Well, I think our positioning was very good throughout the game. Dortmund didn't have many chances. The match was very intense, there were a lot of duels. We gave everything in order to keep a clean sheet and win, and did well. I disagree that it was a hectic finish.

Question: Many predicted Dortmund to be Bayern's fiercest rivals for the Bundesliga title, but now Leverkusen trail the Bundesliga leaders by only four points...

Son: Both Bayern and Dortmund are very strong, but it's no coincidence we're in second place. We have a very strong side ourselves and deserve to be up there.

Question: Will Leverkusen be challenging Bayern for the title?

Son: We shouldn't look to far ahead and start dreaming. As long as we keep up the right attitude we'll continue collecting points. Bayern might be ahead for now, but of course we want to challenge them. Why wouldn't we?

Question: Does the Dortmund win mean a boost at the right time ahead of the Champions League match against Real Sociedad de Futbol on Tuesday?

Son: Every game's important both for the team and myself, but admittedly there's a lot on the cards for the club in that one. We should try and focus on ourselves and not look at the Manchester United against Shakhtar Donetsk encounters. We have every chance of winning if we produce a performance like we did against Dortmund, and if we also get a bit of luck, then we'll progress.
