Pierre-Emerick Aubameyang and Robert Lewandowski are set to create a sub-plot to the Bundesliga title race as they battle to be top scorer.
Pierre-Emerick Aubameyang has thrown down a challenge to Robert Lewandowski after opening his account for the new season with a brace in Borussia Dortmund's 2-1 win over Mainz.
The Gabon international striker, who scored 25 league goals last season, headed his side in front on 17 minutes before converting a penalty late on.
Meanwhile Lewandowski, who topped the Bundesliga goal charts last term with 30, claimed a hat trick in Bayern Munich's opening game which saw the Bavarians hammer Werder Bremen 6-0 on Friday.
