Dortmund has slumped to another Bundesliga defeat, losing 2-1 in Freiburg to fall further behind in the race for Champions League qualification.
Quick-fire goals from Jeong Woo-yeong in the 49th minute and an own goal from Dortmund goalkeeper Marwin Hitz in the 52nd saw the visitors lose their eighth game in 20 rounds on Saturday.
The 16-year-old Youssoufa Moukoko’s 76th-minute strike came too late for Dortmund.
They dropped three points behind Bayer Leverkusen who are fourth on table, the last qualifying place for Europe’s premier competition.
Leverkusen’s 5-2 win over Stuttgart was capped by new signing Demarai Gray’s first goal on his Bundesliga debut after switching from Leicester.
In other matches, former Germany defender Shkodran Mustafi made his Schalke debut despite not training with the team after joining from Arsenal, but his new team lost at home to second-placed Leipzig 3-0.
Schalke remain last and a firm candidate for relegation with just one win and eight points from 20 games.
Wolfsburg consolidated third place by beating Augsburg 2-0, and Mainz boosted its chances of survival by downing 10-man Union Berlin 1-0.
