Costa, Neuer fire Bayern into cup quarters amid busy day in Germany

Berlin - Holder Bayern Munich squeezed into the quarter-finals of the German Cup with a 1-0 win over Wolfsburg on Tuesday following Douglas Costa's first-half strike and goalkeeper Manuel Neuer's heroics.

Bayern was coasting at Munich's Allianz Arena after a well-taken goal from Costa on 17 minutes, but it took two superb saves from Germany shot-stopper to put the Bavarian giant through.

Wolfsburg, who is struggling in the Bundesliga, upped the pace for the final ten minutes as Bayern lost its shape at the back.

Attacking midfielder Yunus Malli, a new signing last month from Mainz, forced Neuer into spectacular parries in quick succession as Carlo Ancelotti's Bayern endured a tense final few minutes.

Costa's goal was a boost for Bayern amidst reports the Selecao forward is considering leaving the German giant to further his career at the end of the season.

Elsewhere, Borussia Monchengladbach won its third-round match 2-0 at second-division Greuther Fuerth thanks to goals by Oscar Wendt and a penalty from Thorgan Hazard.

Gladbach's cause was helped when Fuerth's Hungary international midfielder Adam Pinter was sent off with just 19 minutes gone for a dangerous tackle on Germany midfielder Christoph Kramer.

Hamburg, who toil in the Bundesliga's relegation places, brushed off poor league form, winning 2-0 at home to FC Koln with goals by Gideon Jung and U.S. striker Bobby Wood.

Second division Arminia Bielefeld is into the last eight after a scare against fourth-division minnow Astoria Walldorf, progressing 5-4 on penalties after a 1-1 draw.

In the plum pick of Wednesday's matches, Borussia Dortmund hosts Hertha Berlin in an all Bundesliga tie.
