Germany coach Joachim Low has criticised Chelsea's decision to omit international captain Michael Ballack from their squad for the group stages of the Champions League.
The 31-year-old midfielder is currently sidelined after undergoing ankle surgery in May.
Ballack expects to be back in action by mid-October which would rule him out of just two of the Blues' scheduled six group stages matches.
However, the former Bayern Munich midfielder has been left out of the 25-man squad meaning he would not feature in the Champions League until the knock-out stages in February.
Ballack's omission has led to speculation that he will be offloaded during the January transfer window with his stock set to be higher as he would not be cup-tied in Europe.
But Low is unhappy at the treatment of his captain, who joined Chelsea on a free transfer last summer.
"Chelsea's doctors estimate he will not be able to play for two to three more months," he said.
"But Michael is much more optimistic and expects to play sooner. For us, Chelsea's decision isn't justifiable.
"I discussed it with Michael and he could not fully explain Chelsea's decision to me."
