Bayern Munich striker Mario Mandzukic will miss the Champions League showdown against Barcelona through suspension.
Philippe Lahm, Javi Martinez and Bastian Schweinsteiger should all return to the starting line-up after being rested for Saturday's 6-1 win over Hannover, but long-term injury victims Toni Kroos (groin) and Holger Badstuber (knee) remain absent.
Lionel Messi has handed Barcelona a major boost by returning to full training after missing the last two games with a hamstring strain - though has not been given the all-clear yet.
Defenders Carles Puyol and Javier Mascherano (both knee) and Adriano (suspension) are all out so youngster Marc Bartra is likely to partner Gerard Pique in central defence.
