The Bayern player maintains that the next few weeks will be of little importance to the club, given their 14 point advantage, but warned his side not to falter
Jupp Heynckes' side maintained their near-perfect away form with a 2-0 win over Augsburg, ensuring that they go into the winter break with just one goal conceded on their travels.
In contrast, the champions lost 3-2 at home to Wolfsburg, leaving them 14 points behind Die Roten with Muller conceding that the next few weeks will be 'boring' for his side.
"As a Dortmund player I wouldn't talk that much about the title anymore. The result [of Dortmund] doesn't make us unhappy," the 23-year-old told Sport1.
"The next few weeks [are going to be] boring. We must not dull ourselves with the big advantage that we have right now."
Meanwhile, team-mate Mario Gomez echoed Muller's sentiments, by insisting that Bayern can only stop themselves from winning the Bundesliga title.
He added: "The title won't be decided between Bayern and Dortmund. We can only stop us by leaning back and relaxing."
Heynckes' men encounter Borussia Monchengladbach next weekend at the Allianz Arena in their final league game of the calendar year.
