An early strike from Davie Selke has given Werder Bremen a 1-0 lead over Borussia Dortmund at the halfway stage of their Bundesliga meeting.
It took the hosts just three minutes to break the deadlock as Santiago Garcia stormed into space in midfield before releasing Selke, who held his nerve to curl the ball into the top corner from just inside the box.
Dortmund dominated possession after falling behind, but a lack of quality in the final third of the pitch cost the visitors when they did put Bremen on the back foot.
Melvyn Lorenzen, appearing for just the second time in the league this season, threatened to double his side's lead when he fired just past the post after evading a couple of challenges on the edge of the area.
Jurgen Klopp's side continued to keep the ball impressively, with Ciro Immobile getting more involved as the first half progressed, but the Italian forward and his teammates were left frustrated at the break.
