I think people have picked up the wrong end of the stick here in relation to the comparison between a professional footballer and a doctor.
The original point, that has now been lost, was that someone can be banned from their trade for something that happens outside of that job. This was in reply to Alpine who stated that it would be illegal under European Law to do so.
FYI - I dont have anything against Alpine and was not just picking on him, it was the comment I was addressing, not the poster.
