Taiwo Awoniyi maintained his good form in front of goal, scoring for the second straight game as Union Berlin strengthened their bid for Champions League qualification with a 2-1 victory over Borussia Dortmund on Friday.
It was a first defeat for caretaker boss Erdin Terzic in only his second game in charge after he replaced Lucien Favre five days ago.
Awoniyi, who’s on loan from Liverpool, struck the opener for the home side, in the 58th minute, slotting home off a Grischa Prömel knock-on from a corner kick.
It was his fourth goal in eleven Bundesliga appearances with all four strikes coming in the last six matches.
Teenage sensation Youssoufa Mukoko equalized for Dortmund on the hour-mark but Marvin Friedrich prodded home the winner in the 78th minute to give the home side all three points at the Stadion An der Alten Försterei.
Defeat leaves Dortmund in fourth position on the league table, six points from leaders Bayer Leverkusen and five from second-placed Bayern Munich both of whom face themselves on Saturday.
Union Berlin are up to fifth on the table, a point behind Friday’s opponents in the race for Champions League qualification.
