Michael Ballack has criticised Chelsea's medical staff over his long injury lay-off.
The Blues midfielder, fit again after eight months out, insists it was TWO weeks before Chelsea finally admitted the knock was serious.
"But in the end Chelsea made it clear - unfortunately two weeks late!
"At the beginning of my injury break I constantly had to deny rumours which were created by misleading comments from the doctors.
"I kept hearing that the ankle surgery had not been necessary at all. I had to justify myself, which was really hard for me.
"And on a club level I heard a few remarks made behind my back which were really disappointing for me.
"That was the worst thing in the first week after the surgery that it was reported: Ballack underwent surgery without reason and without permission. For two weeks I had to read this rubbish everywhere.
"Those claims are untrue and the development of the injury proves that. The necessity of the surgery has been confirmed."
