The Bavarians will retain their league title if they beat Hertha Berlin on Tuesday following their latest victory on Saturday
Pep Guardiola said the secret of Bayern Munich's continued success was simply hard work after they moved within sight of the Bundesliga title with a 2-0 win at Mainz.
Goals from Bastian Schweinsteiger and Mario Gotze secured an 18th straight league victory, but victories for Borussia Dortmund and Schalke mean the Bavarians will have to wait to clinch a 24th German crown.
However, the reigning German champions will retain their league title if they overcome Hertha Berlin in the capital on Tuesday.
Guardiola was quick to hail his players as they beat a team who he described as one of their toughest opponents of the campaign.
"We have played against a very strong opponent and won," Guardiola told Bayern's official website.
"We have extended the record to 18 wins in a row. There is hard work behind it. I'm just happy we won against one of the toughest opponents of the season.
"Now we are only missing a victory. We have the chance to become German champions in the capital on Tuesday."
