Pierre-Emerick Aubameyang grabbed a hat-trick as Borussia Dortmund romped to a 6-1 home thrashing of Borussia Moenchengladbach to regain top spot in the Bundesliga on Saturday.

Gladbach had no answer to Peter Bosz's fleet-footed Dortmund, who opened a two-point lead over Hoffenheim at the top in a perfect confidence boost before Tuesday's Champions League clash with holders Real Madrid.

Aubameyang, last season's top scorer in Germany's top flight, has now netted eight goals in six league games – one ahead of main rival Robert Lewandowski of Bayern Munich.

Left winger Maximilian Philipp scored Dortmund's first two goals before Aubameyang's hat-trick, with defensive midfielder Julian Weigl scoring a superb sixth.
