Thomas Tuchel's men, who are tipped to be Bayern Munich's main rivals again in 2016-17, collected all three points at Signal Iduna Park
Pierre-Emerick Aubameyang's brace proved enough to secure a 2-1 victory for Borussia Dortmund in their Bundesliga season opener against Mainz.
The 27-year-old scored 25 league goals for Thomas Tuchel's side last term and opened his account for the new campaign by heading home a cross from Andre Schurrle after17 minutes.
Schurrle was the most impressive of the four recent signings who started for the hosts, but Dortmund's victory was not an altogether convincing one.
