Borussia Dortmund slumped to a 2-1 loss at Union Berlin in the Bundesliga on Saturday, only days after their 7-1 demolition of Celtic for their biggest European win.
Union's Kevin Vogt ended a 10-year Bundesliga goal drought after converting a 26th-minute penalty. Vogt's previous goal was scored on Oct. 18, 2014, making it a record 275 Bundesliga matches between goals for an outfield player.
Dortmund showed none of the aggression they showed in the win over the Scots in the Champions League on Tuesday and before halftime they conceded another with Yorbe Vertessen's low strike from the edge of the box.
Julian Ryerson pulled a goal back for the visitors just past the hour but they could not find an equaliser despite late pressure. Dortmund dropped to seventh place in the standings on 10 points.
