Dortmund striker, Aubameyang is targeting 40 goals in a calendar season, just like Bayern’s Gerd Muller.
Aubameyang scored a brace in the 2-0 win over Ingolstadt, and now has 19 goals in 20 games.
Muller had 17 goals in this stage, as he went on to score 40 goals back in 1971-72 season.
“I still need to score 20 goals to do it, right?” he said to Ruhr Nachrichten when asked about the prospect of surpassing Muller’s record.
“That’s a lot, but in football you never know.”
Aubameyang says his wager with Tuchel is not quite fulfilled, however, despite his stunning scoring form so far.
“It’s true I’ve achieved my goal, but I haven’t yet managed to fulfil my bet with the coach, you’ll have to be patient,” he said.
