Bayern have won their last six Bundesliga games in a row and have scored 17 goals in the process, and depending on other results could move seven points clear at the top.
Werder's last four games have seen 22 goals, but they have one just once in their last six and are beginning to slide down the table.
There is bad news on the injury front for Bayern as Arjen Robben, who was substituted in the 2-0 win over Augsburg, will miss six weeks with a knee injury.
The hosts' coach Robin Dutt may look to reshuffle his defence after conceding four goals last time out, but will not want to change much in attack.
Possible starting lineups
Werder: Wolf; Fritz, Garcia, Lukimya, Gebre Selassie; Caldirola, Ekici, Makiadi, Elia; Hunt; Di Santo
Bayern: Neuer; Lahm, Boateng, Dante, Alaba; Martinez; Muller, Thiago, Kroos, Ribery; Gotze
Sports Mole says: 1-3
