Dortmund can regain top spot with victory at Hamburg on Wednesday, where last season's Torjagerkanone winner Aubameyang will look to improve upon a record of four in four.
The Gabon international scored 31 to Lewandowski's 30 last term as the battle to be Bundesliga top scorer went down to the final day and Aubameyang is happy to play the long game.
"The race is on. When Lewy moves ahead, I am used to catching him up," he told Bild.
"It's enough for me to overtake him shortly before the season finishes."
Lewandowski won the Torjagerkanone during his final season with Dortmund in 2013-14 with 20 goals and hit 30 to finish top of the standings in 2015-16.
