New Bayern Munich signing Joao Cancelo set up a first-half goal to help his side secure a first win of 2023 with a 4-0 triumph at 10-man Mainz in the German Cup on Wednesday.
Choupo-Moting’s 17th-minute strike settled the visitors’ nerves and they had a second on the 30-minute mark when Bayern veteran Thomas Mueller found teenage forward Jamal Musiala, who slammed the ball across the face of goal to make it 2-0.
Winger Leroy Sane scored the third goal with one minute of the first half remaining, sliding in a looped assist from former Mainz forward Choupo-Moting.
Choupo-Moting’s goal and assist kept alive a remarkable record for the Hamburg-born striker, who now has nine goals and five assists in five German Cup matches for Bayern.
Canadian wing-back Alphonso Davies, who came on for Cancelo with 20 minutes to go, added a fourth late in the game, heading in a floated assist from Dutch centre-back Matthijs de Ligt.
Mainz had a number of half chances in an increasingly fiery second half which saw centre-back Alexander Hack sent off for a second yellow card, along with Bo Svensson, who was shown a straight red for arguing with the assistant referee moments before Davies’ goal.
