Pep Guardiola's side have been completely dominant domestically up until this point.
Bayern Munich's stellar start to the season at home has come to an end after they were beaten 3-1 by third place Borussia Mönchengladbach.
Before this weekend's fixture, Pep Guardiola's team had only dropped two points in the league to date, conceding just five goals in their 14 matches.
That all changed today however, as they were uncharacteristically open, allowing Mönchengladbach 13 shots which the hosts took advantage of to slot three past Manuel Neuer.
While Bayern dominated in terms of possession as usual with 60% of the ball and playing over 200 passes more than their opponents, they failed to make the most of their opportunities, and were 3-0 down in the second half after goals from Oscar Wendt, Lars Stindl, and Fabian Johnson.

Franck Ribéry was able to pull one back for the visitors in the 81st minute, but it wasn't enough to spark a comeback that could pull his team back into the game as the home side saw their lead through to the final whistle.
Despite the defeat, Bayern are still top of the table, but their margin of comfort was cut somewhat as Dortmund took advantage of the slip to beat Wolfsburg 2-1 and keep up their title chase.
