Both Jerome Boateng and Arjen Robben are unlikely to be fit for Bayern's Champions League semi-final first leg against Atletico Madrid next week.
Boateng has not played for the Bavarians after picking up a groin injury in January and has returned to training, but the defender revealed he wants to be 100 percent certain of his fitness before returning to match action.
"I am the one who decides when I will return. I want to be training at 100 per cent again first," the Germany defender told Bild.
"The first leg against Atletico is my objective, but we will have to wait and see whether that is a realistic goal. I do not want to take any risks. It's no good when I return and then get injured again, thus missing out on the most important matches.
"I never had any doubts about the Euros, but I obviously couldn't guarantee anything. I just need games to get back to my best."
Robben has been out since the beginning of March with an adductor injury and Bayern head coach Pep Guardiola believes the winger would need a miracle to be fit in time for Wednesday's match, while the player himself remains hopeful but is aware his recovery will take time.
"We are taking things one step at a time," Robben Bild. "I don't know when exactly I will be back. I am hopeful I will make my comeback this season and I am on the right path."
