Good week for:Heiko Herrlich, Arturo Vidal, Home teams, Max Kruse & Fin Bartels
Bad week for: Dortmund, Caiuby, VAR, Cologne
— Bayern's 3-0 win over Augsburg not only put them six points clear at the top of the table, it was also Bundesliga win number 500 for Jupp Heynckes. The 72-year-old won 174 as a player and a remarkable 326 as a head coach. Heynckes has more wins in Germany's top flight than any other.
— Borussia Mönchengladbach climbed into the top four after putting on an attacking masterclass against Hertha Berlin. Unfortunately their backline weren't as on the ball as their counterparts with the six-goal thriller ending in a 4-2 win for the Foals. Nevertheless, head coach Dieter Hecking maintained that he wasn't "offering any dreams".
— For the first time in five years, Schalke ended a Bundesliga Matchday in the top two. The Royal Blues picked up a gritty 2-0 win over Hamburg to move them above Leipzig, but more important, three points clear of bitter rivals Borussia Dortmund, who they face in the Revierderby next weekend.
— After a record-breaking seven consecutive draws to start life under head coach Martin Schmidt, Wolfsburg finally got a win. The 3-1 victory against Freiburg means the club still has yet to lose under their new boss, collecting 10 points in Schmidt's first eight games.
— Bremen picked up their first win of the season in Florian Kohfeldt's first game as head coach. Fin Bartels opened the scoring before Kruse netted a second-half hat-trick, meaning Werder scored as many goals inside 90 minutes as they had in the opening 11 games of the season.
— Robert Lewandowski moved three goals clear at the top of the Bundesliga goalscoring charts, seizing upon Pierre-Emerick Aubameyang's absence in Dortmund's 2-1 loss to Stuttgart, and netting a brace against Augsburg.
— Max Kruse sent a timely reminder to Germany head coach Joachim Löw of his goalscoring abilities as he inspired Werder Bremen to a convincing 4-0 win over Hannover 96 at the Weser Stadion. Having not scored yet this season, Kruse took home the match ball after scoring three times in the space of 23 minutes.

In Mainz, referee Dr. Felix Brych awarded a penalty after consulting with the VAR for an apparent foul on Pablo de Blasis by Frederik Sörensen. The video review showed no contact, suggesting a perfect chance for the technology to step in and make the game fairer. However, the penalty was awarded, Mainz scored and ended up winning the game as a result. Cologne's frustration grew afterwards when Brych said that in his exchange during the decision he was informed there had been contact and that was also reiterated after the game. In the end, Cologne were still without a win after 12 games.
— Cologne's Frederik Sörensen picked up a yellow in Mainz and will now miss the club's game vs. Hertha Berlin. The Cathedral City side will also be without Simon Zoller for the remainder of the year after the forward picked up a thigh injury in Mainz.
