Chuopo-Moting opened the scoring in the 24th minute, Thomas Mueller converted a penalty a little later for the quintuple winners after Cgoupo-Moting was brought down, and Choupo-Moting wrapped up matters into the top left corner with 15 minutes left.

“You have to win in the cup. It is nice to be back in Germany and to score two goals,” Germany-born former Bundesliga player Choupo-Moting, who arrived on transfer deadline day from Paris Saint-Germain, told Sky TV.

Dueren’s Mario Weber said after the narrow defeat: “I am very satisfied and proud of my team. It was an honour to play here and to compete with the best in the world.”

With many players on international duty Tuesday and Wednesday and the next Bundesliga amtch at Arminia Bielefeld set for Saturday, Munich coach Hansi Flick fielded five newly-signed players in Choupo-Moting, Bouna Sarr, Marc Roca, Douglas Costa and goalkeeper Alexander Nuebel.

The 17-year-old talent Jamal Musiala was a starter and 19-year-old substitute Angelo Stiller made his first-team debut.

The match was originally scheduled for mid-September but postponed to give Bayern some rest after their title winning Champions League campaign the previous month.

Dueren gave up their automatic home field advantage because it was easier to comply with safety and hygiene protocol in Munich’s arena. The game took polace behind closed doors owing to coronavirus restrictions in Bavaria.
