Bavarians are now three points clear of newly promoted side
RB Leipzig have been the Bundesliga's surprise package this season as they rose to the top of the table.
In their debut season in the top flight, the Red Bull backed Leipzig had already arrived in the top flight as arguably the most disliked club in Germany as European football writer Andy Brassell explained in an in-depth piece for Newstalk.com.
As he detailed, German fans see their rise as "corporate rebranding, flying in the face of what many German football fans believe represents the tradition and soul of the national game".
On Wednesday night and with the winter break looming, Leipzig faced the country's true power club Bayern Munich away with the half-season champions tag on the line.
In the end, Bayern ran out 3-0 winners at the Allianz Arena in Munich.
Thiago Alcantara put the Bavarians in front on 17 minutes after Robert Lewandowski had hit the post.
Then Xabi Alonso added a second eight minutes later.
On the half hour mark, Leipzig's night went from bad to worse when key man Emil Forsberg was sent off for a bad challenge on Philippe Lahm.
And by half-time, the game was over as a contest as top scoring Lewandowski made it 3-0 from the penalty spot.
Bayern are now three points clear of the newly promoted side at the top of the Bundesliga after 16 games.
It's only Leipzig's second league defeat of the domestic season.
Hertha Berlin are third in the Bundesliga, six points behind Leipzig.
Borussia Dortmund go into the winter break in sixth place, three points off the top three, with Eintracht Frankfurt and TSG Hoffenheim fourth and fifth.
