Doesn't "going off the rails" mean partying too much? As you say, for a professional footballer the bar is very low, especially during the season. Far lower than for us normal folk. If maybe I had a couple of lemonades too many on a Thursday evening and so coasted a little on the Friday then...
It must be so easy to go off the rails being given so much money and fame so young. Had it happened to me I suspect I would have been found dead in a ditch by age 27. it would have been fun whilst it lasted though :cool:
