If he has a serious health issue then why is he being cleared by medical staff to start games (or start as a sub) for the club?
Genuinely horrendous treatment of him by our medical staff if we are putting him up for selection if he is mentally unwell or physically not up to it (or both). If he's putting himself up for selection despite medical staff's advice, that decision should be taken away from him.
To be honest, despite many posters claiming there must be a health concern, weight loss etc, I find it really hard to believe the club would be playing him through it. If we are, then the club should take a majority chunk of the blame for his continued poor form.
