that's a fair point. There's a nuance to that, mental health can indeed affect your decision making, but it doesn't mean all decisions and actions can just be attributed to that.
I'm willing to believe that he does indeed just struggle to get and stay fit despite his best efforts, and that poor time keeping may indeed be a symptom of some disorder, but I find it hard to believe that also applies to his decision to refuse any and all transfers. Again, I accept that mental health can affect judgement, but if he wanted out of the limelight a move away would be best.
His past comments about Mourinho and joining RM(?) also don't help his case.
