Dortmund - He's the man who purportedly once clocked a faster time over 30 metres than athletics legend Usain Bolt, but now it is the goals of Borussia Dortmund speedster Pierre-Emerick Aubameyang that are doing all the talking.

The Gabon international netted the seventh brace of his Bundesliga career in BVB's topsy-turvy 4-2 win away to Hannover 96 on Matchday 4 and is currently second only to FC Bayern München's Thomas Müller at the top of the leading scorers charts.

20-goal mark on the radar

"Without getting ahead of myself, I'd really like to score at least 20 goals in the Bundesliga this season," Aubameyang said at the start of the 2015/16 campaign, having followed up his debut season 13-goal haul with a career-best 16 Bundesliga strikes last term. "At least!"

Already with five goals in four league games, however, the 26-year-old is on course to meet his lofty target. More importantly, it is abundantly clear that he is deriving immense pleasure from playing football under the tactically astute Thomas Tuchel. Saturday's audacious Antonin Panenka-inspired penalty - his second spot-kick of the afternoon at the HDI-Arena - attests to that.

At home in Dortmund

"I'm really happy at the club, in the team and in this city," Aubemeyang enthused after it was confirmed the AC Milan youth product had put pen to paper on a two-year contract extension on 31 July 2015. "BVB is like a second home to me. My heart's here and I never wanted to leave." Happiness yields results and that is most certainly the case for BVB's carefree No.17 who, as well as scoring in six successive Bundesliga matches dating back to last season, has bagged himself more goals in all competitions in 2015 (23) than any other player in Germany’s top flight.

Leverkusen in his sights

"Auba's really come on leaps and bounds since joining the club [in summer 2013]," explained BVB sporting director Michael Zorc. "He always sets himself high standards and doesn't let things get to him. If we can keep him in top shape, the goals will continue to flow."

Aubameyang has never scored against Dortmund's upcoming Bundesliga opponents Bayer 04 Leverkusen, but with credible designs on hitting the 20-plus-goal mark - a number typically associated with the Bundesliga's end-of-season Torjägerkanone winner - the aspiring Torschützenkönig could be about to break his duck.
