The France international midfielder believes that vanquishing their great rivals is of the utmost importance for Pep Guardiola's men when they return from the international break
Goals from Jerome Boateng, Franck Ribery and Thomas Muller helped the Bavarians to a 3-0 win against Augsburg on Saturday, thus extending their unbeaten streak in the league to 37 games, breaking a 30-year-old record in the process.
The Ballon d'Or nominee was delighted at having netted at the Allianz Arena but wasted little time in turning his attention to Bayern's November 23 showdown with rivals Dortmund.
"The second goal was important for myself and the team. We did well, were very aggressive and played better than last time out," Ribery told bundesliga.com.
"The next game against Borussia Dortmund is vital for us. It's a great chance to build a lead at the top and extend our record."
Coach Pep Guardiola, however, warned of the dangers of complacency and called for greater consistency from his troops.
"We started well and the early goal made it easier," the former Barcelona boss told the club's official website of the victory, "but we didn't play so well after that.
"It was better in the second half; we controlled the game and created a number of big chances. Now I hope my players come back fit after the international break."
