BIELEFELD, Germany (Reuters) - Third division Arminia Bielefeld stunned Bundesliga club Werder Bremen with a 2-1 victory in a major German Cup upset on Tuesday to reach the competition's semi-finals.
The hosts, who have now eliminated three Bundesliga clubs in a row following wins over Union Berlin and Freiburg in the previous rounds, went in front after Werder lost possession in their own half and Marius Woerl curled his shot in after 35 minutes.
