BERLIN (Reuters) - Bayern Munich's Douglas Costa scored a first-half winner as the holders did the bare minimum to beat VfL Wolfsburg 1-0 on Tuesday and move into the German Cup quarter-finals.

The Brazilian's 18th-minute shot, which was deflected past keeper Koen Casteels by Wolfsburg's Luiz Gustavo, was enough to beat the toothless Wolves, who did not register a shot on goal for 82 minutes.
