The German side suffered a convincing defeat at the hands of Giovanni van Bronckhorts team on Thursday
Borussia Dortmund endured one of their worst defensive performances in European competition in their history as they suffered a 4-2 loss at home to Rangers.
The German side have a mountain to climb in their Europa League knockout round play-off tie against the Glasgow side after losing at home on Thursday.
Their display against Giovanni van Bronckhorst came as a severe disappointment for captain Mats Hummels, who criticised his side for another defensively sloppy display at home.
“If you look at the Leverkusen game [a 4-2 loss for Dortmund], we conceded four goals after unnecessarily losing the ball,” Hummels said after Thursdays game.
“That happened with the first, second and fourth goals here.
“I think we know what our problem is. The coach mentions it often enough.
“We’re playing an awful lot of nonsensical football, a lot of illogical football and making our opponents so strong.
“Our football is also too complicated. If we play this way, we’ll sometimes win and sometimes lose but over the piece we won’t have success.”

Dortmund found themselves trailing 2-0 by half-time through goals from James Tavernier and Alfredo Morelos.
John Lundstram made matters worse for the hosts when he put Rangers three goals ahead four minutes after the restart.

Jude Bellingham pulled one back for the home side two minutes later, but an own goal from Dan-Axel Zagadou restored Rangers lead.
Raphael Guerreiro limited the damage again with eight minutes left to go to give the Bundesliga team a chance in the second-leg.
It is just the second time Dortmund have conceded as many as four goals at home in a European match, having last done so in 2016 against Legia Warsaw, which they won 8-4.
