The German Bundesliga's biggest game will be witnessed on Saturday, when runaway leaders Bayern Munich host defending champions Borussia Dortmund in an absolutely must-win game for the latter.

Dortmund know nothing but three points will do, after seeing Bayern's lead increase to 11 points, following the matches in midweek.

Bayern have 37 points from 14 games, while Dortmund are third on 26 points, one behind second-placed Bayer Leverkusen.

"We know how to play there," Dortmund manager Jurgen Klopp said. "In Munich they have more depth and quality than anywhere else. You can change eight players and you still have a top European team. We already found out in the Super Cup that Bayern are a different side this year. They are greedy and gritty."

Dortmund will have Mats Hummels available, while Mario Gotze is also expected to lineup against Bayern. Ilkay Gundogan though is a major doubt.

"Mario has so far only been able to do a few running drills but it still looks good for him," Klopp said. "With Illie, we just have to wait and see."

"I´m doing a lot better and today was able to train normally with the team again," Hummels added. "I firmly expect to play."

Bayern manager Jupp Heynckes will welcome back Bastian Schweinsteiger after the midfielder was rested for the midweek game against Freiburg. Luis Gustavo and Arjen Robben, however, are ruled out.

"Our target is not only to maintain the lead but to extend it," Heynckes said. "He's (Schweinsteger's) a very important component in my system."

"Obviously, you want your best players on the team in the biggest matches, and Bastian is definitely one of our most important players," skipper Philipp Lahm added. "Dortmund definitely won't be coming to Munich just to gift us the three points."
