Unless I've missed it, I am very surprised that mental health hasn't been brought up as a potential explanation for it all.

No reason at all why White might not be suffering with some depression and then going off to Qatar for a month in that sort of pressure cooker isn't a bit too much for it so he is released to have some time back home and concentrating on himself.

Mental health is about as stigma'd as being gay in football so it makes sense they'd gloss over it with a "personal reasons" excuse and a potentially leaked nonsense story of a bust up with Stevie H.
