Bundesliga.com jumps into the ring with the two goalscoring heavyweights to judge how their contest for the Torjägerkanone title has been waged so far.
There was no sizing each other up, no sparring, as both men came out punching. Lewandowski delivered the first blow, striking in the curtain-raising 5-0 defeat of Hamburger SV, the biggest-ever first-day win. Aubameyang countered as Thomas Tuchel’s reign as Dortmund coach began with a thumping 4-0 win over Borussia Mönchengladbach.
On the ropes after Kevin Volland's record-equalling strike just nine seconds in, Bayern hit back against TSG 1899 Hoffenheim with Lewandowski summoning the strength to come out of his corner to deliver a last-minute knock-out blow. Aubameyang left it later still to double his season's tally in Dortmund's 4-0 romp at FC Ingolstadt 04.
Verdict: Aubameyang on points
Back in the starting line-up, Lewandowski missed the chance to get the upper hand, pulling his punches during his club's 3-0 win over Bayer 04 Leverkusen. Aubameyang was relentless, however, jabbing home to cap a neat Dortmund move in a 3-1 home win against Hertha Berlin.
Verdict: Aubameyang quicker to the punch
A traditional Saturday kick-off time for both men gave them the chance to trade blows simultaneously. While Lewandowski landed a solid one in helping Bayern come from behind to win against FC Augsburg, Aubameyang delivered a ruthless one-two combination from the spot in victory over Hannover 96.
Verdict: Aubemayang edges further in front on the scorecard
With Lewandowski not featuring for Bayern at Darmstadt, Aubameyang's penalty in Dortmund's 3-0 defeat of Leverkusen meant this round was declared a 'no contest'.
Verdict: Aubemayang by TKO
Having run up the Glockenspiel and chased the proverbial chicken around the Säbener Strasse training centre, Lewandowski floated like a butterfly, stung like a bee against VfL Wolfsburg! His five-goal onslaught in a bruising nine minutes for the Wolves left the whole of German football punch-drunk. Even Aubameyang could muster only a featherweight response, though his seventh strike of the campaign saved Dortmund from defeat in Sinsheim.
Verdict: Do you really need to ask?
The tide had appeared to have turned in Lewandowski's favour when he plundered two of Bayern's three goals at 1. FSV Mainz 05, bludgeoning his way through the century barrier for Bundesliga strikes at the same time. Aubameyang made a good fist of things, though, responding with a devastating double strike of his own, but Dortmund were pegged back late on by SV Darmstadt 98.
A classic contest turned into Der Klassiker as the pair came face-to-face in the Allianz Arena. Aubameyang's first-half blow meant the Dortmund man became the first to score in all eight opening games of a season, but it proved little more than a slap in the face as Lewandowski delivered the coup de grace with a brace in a punishing 5-1 Bayern win.
Verdict: Lewandowski by KO...but Aubameyang has not thrown in the towel.
