BERLIN, Sept. 25 (Xinhua) -- Denis Zakaria's first-goal was enough for Borussia Monchengladbach to beat ten-men Borussia Dortmund 1-0 in the sixth round of Bundesliga on Saturday.
The "BVB" caught a promising start on the road and thought they had opened the scoring with only eight minutes played but Mats Hummels' header from seven meters was ruled offside.
It remained the only noteworthy chance for a long time as both sides neutralized their actions and disrupted the flow of the game with many fouls.
The spectators had to wait until the 37th minute to finally see some action on the pitch as Zakaria danced through Dortmund's box before trading passes with Matthias Ginter and beating goalkeeper Gregor Kobel from close range, making it 1-0 on the scoreboards.
To make things worse for the visitors, Mahmoud Dahoud received his marching orders three minutes later, after booking his second yellow card for a foul play.
The "Foals" took the reins again after the restart and kept Kobel busy as he parried Jonas Hofmann's effort from tight angle in the 55th minute before palming away Zakaria's shot from 20 meters in the 74th minute.
Monchengladbach continued on the front foot, but Dortmund looked dangerous on fast breaks. Jude Bellingham created a good free-kick position for Raphael Guerreiro's, whose shot got blocked by the wall in the 88th minute.
Dortmund produced another chance moments later when Monchengladbach failed to clear the ball from the area allowing Thorgan Hazard to head over the target from promising position.
It remained Dortmund's last chance of the game as the hosts protected their narrow lead until the final whistle, sealing Dortmund's second loss of the season.
Monchengladbach secured its second win of the campaign and move on the 11th spot whereas Dortmund slump from the third to the fourth position on the Bundesliga table.
"The dismissal of course made our life more difficult, also because we were already one goal behind. We played okay in the second half and created a couple of half-chances," Dortmund defender Hummels said.
"It was a tough game. We are very happy about the three points. We worked hard and now we have to continue like this," Monchengladbach midfielder Denis Zakaria said.
