Our entire defensive play was a catastrophe , '' Bayern coach Jupp Heynckes said . `` We have to take the blame and we did not deserve to win . `` We still have a major goal in mind and I think we will have all recovered from the shock by the Champions League final . That will be a completely different game . '' Bayern started shakily when a mistake by Luiz Gustavo allowed Jakub Blaszczykowski to set up Japanese forward Shinji Kagawa for the first goal after three minutes . The stage looked set for a close contest though when Arjen Robben made it 1-1 from the penalty spot on 25 minutes after Dortmund goalkeeper Roman Weidenfeller tripped Mario Gomez . But Dortmund were 3-1 in front by half time thanks to a penalty by Germany defender Mats Hummels after Jerome Boateng 's foul on Blaszczykowski and Lewandowski 's first from a perfect Kagawa pass .
