Eric Maxim Choupo-Moting marked his Bayern Munich debut with two goals in a 3-0 win over fifth-division Duren in the German Cup first round on Thursday. The Cameroon striker, signed from Paris Saint-Germain as back-up to Robert Lewandowski, grabbed his goals in the 24th and 75th minutes. To round off his successful evening, the 31-year-old also won the 36th-minute penalty which was converted by Thomas Mueller. Bayern coach Hansi Flick rested most of his first-choice players who had been away on international duty. Duren had given up home advantage for the tie which was played behind closed doors at Bayern's Allianz Arena. cpb/dj/mw
