Bayern's first match of their Treble defense season went as planned. Around 80% possession and five goals tallied with a slightly less than full-strength squad in Osnabrück, due to Rehden's lack of facilities fit for the ticket demand and media requirements. The atmosphere was that of a Bayern home match- if not louder.
Notably, Lahm, Ribery, Martinez and Boateng did not start this match with the Bundesliga season only four days away.
To Rehden's credit, they played the first half more capably than many a first division side have done against Bayern in recent seasons. They didn't begin putting 10 or 11 in front of goal until the last ten minutes of the half, and until that time had, for the most part, played Bayern man-for-man while trying to get a goal of their own.
BSV actually had a good chunk of the attacking play through the first fifteen minutes, but failed to test Neuer's goal in any significant fashion until the 28th minute when a chip from Alexander Neumann on the left beat Neuer but was headed wide in the first place, and nearly rolled out for a throw in. On the play, Rafinha was poorly positioned, which allowed for the final pass to be made from Danny Arend to Neumann and for the chance to be created. By that time, Bayern had already landed the first blow and were up 1-0.
An Alaba pass from the endline found Robben in the middle of the box, who danced around and unleashed a shot that looked to beat Milos Mandic but a Shaqiri toe-nudge assured this and put Bayern into the lead.
Rehden's other good opportunity, if you want to call it that, came from a run down Van Buyten's side that the pressing Belgian couldn't quite keep up with without shouldering and tugging his opposition. The Rehden man went down and appealed to the referee but no penalty was awarded.
The rest of the half saw a tired BSV try their best to take the one goal deficit to the locker room.
This task was nearly accomplished, but for a last-minute goal from Thomas Müller. A Bayern corner had Müller running into the box as the furthest man forward. When the corner was taken short, Rehden appeared to forget about the lanky forward until it was too late and a Rafinha cross had met Müller's head and was in the back of the net.
Just thirteen minutes into the second half, Bayern put the match out of reach with another goal from Thomas Müller after he drew the penalty moments before when Stefan Heyken made plenty of contact in the area and received a yellow card in addition to the foul.
Six minutes after that, Müller got his hattrick after a Robben pass enabled Bayern's number 25 to get his third on the day at a point when Bayern were retaining 80% of possession and truly dominating Rehden like most thought they would.
Rehden would finally get their golden opportunity to grab one back after a brilliant Danny Arend run left the Bayern line rooted to their spots, but Arend pulled the trigger perhaps a bit early and let loose a powerful shot that curled wide at the crucial moment.
Robben finally got his goal after so any great Mandic saves two minutes from time. Müller's ball set up the Dutchman's long-awaited goal that was brilliantly tucked into the upper corner.
All-in-all, a solid performance from both teams, especially from Thomas Müller, Arjen Robben and Rehden's Milos Mandic in goal. Bayern now await the draw for their second round match of the DFB-Pokal which will take place towards the end of September.
