Douglas Costa was also on target as Pep Guardiola’s side picked up a convincing win at the Volkswagen Arena to go through to the third round of the competition
Bayern Munich claimed a comfortable 3-1 win over Wolfsburg on Tuesday to advance to the third round of the DFB-Pokal.
Bundesliga champions Bayern dominated from start to finish at the Volkswagen Arena on Tuesday, and were three goals to the good at half-time thanks to a brilliant attacking display.
Muller netted twice with clinical finishes, but could just as easily have had a hat-trick if it were not for Diego Benaglio’s heroics in the Wolfsburg goal.
Costa opened the scoring after 15 minutes with an unstoppable drive from just outside the box, and the Brazilian winger was a constant menace throughout.
Dieter Hecking’s Wolfsburg were more solid at the back after the break and claimed an injury-time consolation through Andre Schurrle, but their defence of the trophy came to an early end as Bayern outclassed them.
Bayern could have opened the scoring after just five minutes, when Muller saw an effort saved by Benaglio, but it did not take long for Pep Guardiola’s side to take the lead in style.
Muller passed to Costa outside the area, and the former Shakhtar Donetsk man danced past his marker before firing in a powerful shot into Benaglio’s top-left corner from 20 yards.
