( CNN ) -- Pep Guardiola 's first competitive game in charge of Bayern Munich ended in defeat on Saturday as Borussia Dortmund ran out 4-2 winners in the German Super Cup . Two goals from Marco Reus helped Jurgen Klopp 's team beat the reigning German and European champions in front of a home crowd at the Signal Inuna Park . Dortmund always held sway in an absorbing contest but Bayern , minus Franck Ribery and former Dortmund midfielder Mario Goetze , were never far behind . Klopp 's men were gifted the opening goal in the sixth minute when Reus headed home from close range after Bayern keeper Tom Starke -- deputizing for an injured Manuel Neuer -- had fumbled a cross . Dortmund were unlucky not to double their lead moments later when Robert Lewandowski scored , but he was adjudged to be offside . Bayern fought back and were denied in the 12th minute by a fine double save by Roman Weidenfeller who blocked Xherdan Shaqiri 's low shot before palming away a rebound effort to safety . The half ended as it had begun with Dortmund with their noses in front but it was Bayern who struck first after the break -- Arjen Robben heading home in the 54th minute to level the scores . The goal sparked a frantic passage of play which saw four goals in ten minutes . In the 56th minute , Dortmund regained the lead when Daniel van Butyen scored an own goal and 60 seconds they were 3-1 up thanks to a wonderful curling effort from Ilkay Gundogan . Bayern halved the deficit eight minutes later when Robben received a cross from Philipp Lahm , before turning and firing a left-foot shot past Weidenfeller . But it was Dortmund who finally finished the contest in the 86th minute when Reus steered Pierre-Emerick Aubameyang cross into the net to bag a brace and ensure Dortmund made a winning start to the season .
