Dortmund defeat sees it drop into bottom half
Borussia Dortmund was beaten 1-0 at home to Augsburg as its nightmare season worsened.
Niko Kovac's side dropped to 10th on the table after the defeat and trails the top four having played a game fewer than fourth-placed Eintracht Frankfurt.
The hosts fell behind in the 23rd minute when Jeffrey Gouweleeuw nodded home for Augsburg with its first chance of the game.
Julian Brandt thought he had drawn level after tapping in at the far post from Nico Schlotterbeck's knockdown, but he was adjudged to be offside after a lengthy video assistant referee (VAR) review.
The home side controlled the remainder of the match at the Westfalenstadion, but was unable to find a way past a stubborn Augsburg defence despite winning nine first-half corners.
In the second half, Dortmund had 77 per cent of the possession but only managed to work the visiting goalkeeper once and was ultimately left frustrated.
It travels to Lille next for the second leg of their UEFA Champions League Round of 16 tie, having drawn the first leg 1-1 at home. Next up in the league is a trip to RB Leipzig next weekend.
