DHAKA: Franck Ribery marked his first start since recovering from a troublesome back problem with a goal as Bayern Munich kicked off the defence of their DFB-Pokal crown with a comfortable 3-1 win at Hamburg.
Robert Lewandowski opened the scoring just seven minutes into the game at the Imtech Arena and David Alaba doubled the visitors' advantage with stunning long-range strike just before the break.
Ribery then made it 3-0 with a deflected strike 10 minutes after half-time, rendering Pierre-Michel Lasogga's late header purely academic.
However, the game ended on a sour note, with a supporter invading the pitch just before the full-time whistle and striking Ribery in the face with his scarf.
Victory sees Bayern keep their hopes of a third successive DFB-Pokal title alive, while Hamburg's attentions will turn to league survival.
Hamburg made three changes for the contest, but they were let down by a first-team regular in the seventh minute as Thomas Muller intercepted a misjudged back pass from defender Westermann and fed Lewandowski, who found the net at the second attempt.
The visitors were dominant and Philipp Lahm came close to doubling Bayern's lead on 43 minutes only to be denied at point-blank range by Jaroslav Drobny, but the goalkeeper could do nothing about Alaba's sensational strike a minute later.
Having received a pass from Xabi Alonso, the Austria international pushed forward unchallenged into the Hamburg half, before unleashing a swerving 35-yard effort that a wrong-footed Drobny could not keep out.
Hamburg found themselves three goals behind on 55 minutes as Ribery found the back of the net.
Juan Bernat raced down the left and played a pass into the Frenchman's feet. He cut inside two defenders before seeing a low drive deflect off Djourou on its way in.
Three minutes later it could have been four but the Hamburg keeper got down well to deny Muller, and Manuel Neuer was called into action for the first time on 68 minutes when Lasogga found room 20 yards from goal to hit a powerful effort.
Bayern boss Pep Guardiola rang the changes just after the hour but the visitors continued to press and Ribery was denied a stunning second goal in the 73rd minute, reports goal.com.
Substitute Sebastian Rode made good ground down the right and his cross was met by the winger but his technique-laden volley was brilliantly tipped around the post by the goalkeeper.
Hamburg finally got themselves on the scoresheet with five minutes remaining as Lasogga met a Rafael van der Vaart cross at the back post to head beyond Neuer.
The game ended on a sour note as a crowd member ran onto the pitch and appeared to lash out at Ribery, sparking angry reactions from players from both sides, and referee Marco Fritz immediately blew the final whistle after the invader was taken away.
