The first half played evenly, as expected, between the two sides that entered the matchweek separated by just two points.
Frankfurt got their breakthrough in the 28th minute after a break down the right side when Kerstin Garefrekis laid the ball off to her right to Bianca Schmidt, who crossed it into the area. In a bit of a scramble in at goal, Celia Sasic got her foot to the cross first, and left Längert with no chance as she put her side into the lead.
Frankfurt's second goal came in the 46th minute off a potentially controversial penalty call against Niki Cross and FC Bayern when the American defender made contact with Lira Bajramaj that was deemed to be penalty-worthy. The call didn't make sense to some at the time, because Cross appeared to get the ball on the challenge before making any sort of contact, which didn't seem to be foul-worthy. If anything, the penalty should have been called seconds earlier when Cross blocked off Schmidt at the top of the box without getting any of the ball.
In any case, Bajramaj made easy work of the penalty she was awarded and smashed her attempt into the top-left corner of the net directly after halftime.
Cross atoned for her mistake on the defensive end with a goal some 20 minutes later.
Bayern had earned a corner and Sarah Hagen got her head on Romert's delivery and sent it towards goal. Cross, realizing it didn't have the pace or height to make it past the Frankfurt defenders and goalkeeper, took a touch with her head and ensured the score for the Reds in the 65th minute.
Only three minutes later, FFC scored a third to make the task even harder for the Bavarians, who likely couldn't tell you how the third goal even went in after a mess of players on the box, much like the first goal, managed to score for Frankfurt.
The in-swinging freekick from the right was well-placed, but Bayern did a very good job of marking all threats. Peggy Kuznik had FCB's Clara Schöne essentially on her foot but Kuznik managed to score anyways, putting her team up 3-1.
Bayern would surrender their fourth goal in an equally odd manner, though not in such a blameless one. A quarter-hour from the end of the match, under immense Bayern pressure in her own half, Meike Weber hoofed the ball forwards. After a directed header, suddenly Frankfurt were in behind the entire Bayern back line and all that was left was a simple tap-in by Sasic for her second goal of the match.
Bayern now sit in 4th with 10 points behind leaders Turbine Potsdam with 13 and Wolfsburg/Frankfurt on 11.
The Bayern-Mädels play next on October 20 at home against Bayer Leverkusen.
