Sebastian Prödl is doubtful for the match and could be replaced by Assani Lukimya.
In midfield, manager Schaaf is unlikely to make any changes after playing the same formation for several weeks now.
Zlatko Junuzovic is one yellow card away from suspension.
Nils Petersen is ahead of Joseph Akpala in manager Schaaf's thinking for the spot up front.
Schalke regained confidence in the Champions League during the week, coming back from 0-2 down against Arsenal. It remains to be seen how tired some players will be after that match.
Bremen have won two of their last three games and the team look to finally be fulfilling the attacking potential they have. The defence remains a concern though, against a strong team like Schalke, especially with Sebastian Prödl not 100% fit.
Expect this to be a close game from the outset. Both teams have great attacking quality and need to be careful defensively.
