Bayern edge Wolfsburg to reach Pokal quarters; Bobby Wood lifts Hamburg

A first-half strike from Douglas Costa was enough for holders Bayern Munich to edge Wolfsburg 1-0 at home and scrape into the DFB Pokal quarterfinals on Tuesday.

Costa scored with a deflected shot in the 18th minute, but Bayern failed to build on their greater possession and were made to suffer late on as Wolfsburg grew in confidence.

Yunus Malli should have equalised with less than 10 minutes remaining, but Manuel Neuer denied his solo effort and the Bayern goalkeeper was called into action again to deny Daniel Didavi.

Late substitutions helped Bayern hang on and take the momentum from Wolfsburg, but there were whistles from home supporters unhappy with the display.

Bayern coach Carlo Ancelotti has come in for some criticism following a dip in performance of late and the first dropped points in the Bundesliga after seven games at the weekend.

Thomas Muller was left out, while Thiago Alcantara returned from injury and Philipp Lahm and David Alaba also started.

American forward Bobby Wood sealed Hamburg's progress with a goal in a 2-0 victory over Cologne on Tuesday.

Gideon Jung got the home side off to a flying start in the fifth minute, though Cologne came close to equalising through Anthony Modeste.

With 15 minutes remaining, Wood intercepted a wayward pass from Pawel Olkowski in midfield, sprinted forward and played a one-two with Jung before staying cool in front of Cologne keeper Thomas Kessler to score.

Hamburg's Luca Waldschmidt hit the post a minute before.

Borussia Monchengladbach took advantage of an early red card for second-tier Greuther Furth to win 2-0.

Oscar Wendt had already scored in the 12th minute when Adam Pinter was sent off for the hosts six minutes later. Thorgan Hazard converted a penalty in the 36th minute to put the game beyond doubt.

Meanwhile, second-tier Arminia Bielefeld advanced past fourth-division Astoria Walldorf on penalties, winning the shootout 5-4 after a 1-1 game.

Walldorf had equalised late through Marcel Carl to take the match to extra time, but though Arminia had Keanu Staude sent off in the 116th minute, they prevailed from the spot.
