Borussia Dortmund scored four second-half goals to overcome newcomer Ingolstadt in a one-sided affair and Mainz edged Monchengladbach 2-1 to close the second round of the German Bundesliga.
Dortmund overpowered resilient Ingolstadt during the match on Sunday, who were unable to hold the pace with the "BVB" in the second half, Xinhua reported.
Following the win, Thomas Tuchel's men wrapped up their second win in as many games to climb a top of the Bundesliga standings.
The "BVB" controlled the proceedings for most of the time but lacked in accuracy during the first half. Neither Marco Reus nor Pierre-Emerick Aubameyang were able to break the deadlock from promising positions.
Ingolstadt nearly flabbergasted Dortmund in the match but goalkeeper Roman Buerki was on guard to deny the hosts the opener.
However, just as Ingolstadt gained a foothold into the game, Dortmund broke the deadlock through Matthias Ginter 10 minutes into the second half.
Dortmund gained momentum and doubled the lead thanks to Ingolstadt's Moritz Hartmann, whose foul play to Marcel Schmelzer inside the box allowed Reus to convert the awarded penalty with 60 minutes into the match.
