Unstoppable Bayern Munich travel to face third placed Hoffenheim on Tuesday and it's two in, one out for the Bavarian club.
The German giants have been preparing for their next match without Thomas Muller, who picked up a knock to his ankle during his second goal of the 6-0 drubbing of FC Augsburg.
Manager Carlo Ancelotti confirmed the attacker's injury in his press conference after the game. As quoted by the club's official site, he said:
"He needs a two-day break. We'll have to see whether he'll be fit to face Dortmund. We're certain he'll be ready to play again when we face Real."
Muller hasn't enjoyed his finest season in the red of Bayern for 2016/17, scoring just four league goals in 23 Bundesliga appearances - by contrast, Robert Lewandowski has plundered 24 in 26 in the league.
It is somewhat of a frustrating period for the forward who, rather disappointingly, failed to score a single goal at last year's Euros.
While Muller is ruled out against Hoffenheim, Bayern will be able to recall Spanish duo Javi Martinez and Xabi Alonso to the side after they served their suspensions.
The pair have not been missed, but it is good news for the club to have them back for a potential banana skin game against Julian Nagglesmann's side.
Ancelotti also offered updates on several other players in his squad - Manuel Neuer and Thiago will both be rested, and Douglas Costa is working his way back and could be in contention for the European clash with Real Madrid.
