- Robben and Ribery have both struggled with injury this season.
- Bayern are 1-0 down to Atletico Madrid heading into their Champions League semi-final second leg.
- Reds were denied lifting a fourth consecutive league title after drawing Gladbach on Saturday.
"It's not going as well as expected, not as good as it should, but we're persisting and battling with it to try and allow me to still play a role this season," Robben told Bayern's TV channel ahead of Saturday's 1-1 draw with Borussia Mönchengladbach. The Netherlands international has not played for two months due to an adductor problem.
Ribery missed the Matchday 32 game with a back problem, and coach Pep Guardiola admitted the Frenchman may not be fit for Tuesday's return fixture against Atletico on Tuesday with Bayern trailing 1-0 from the first leg.
"At this moment in time, I don't know," said Guardiola, who brought Ribery off the bench in the Spanish capital on Wednesday. "We'll try everything to get Franck there."
