Werder Bremen management are wary over Naby Keita's fragile fitness record.
The former Liverpool midfielder joined Werder over the summer, but has struggled to get on the pitch due to injury.
So far, Keita has managed just the three appearances.
BILD says Keita is now not expected to return until after the November international break.
And Werder management are taking a 'no risk' policy, as they wait for Keita to be completely clear of injury before bringing him back into training.
