i'm not so sure. i agree with you that theres a good chance that the original TSF is kitson. but i just remeber that there seemed to be some irregularities when reading the books for it all to have been kitson.
I agree.
I thought that this was an interesting read from a few months back

With a bit of digging, it shouldn't be too hard to figure out who this is. A bit of a lad, around the fringes of the squad when Capello was appointed, but subsequently not picked. Can't remember Kitson's name ever being mentioned as an England international.
There is a damming piece of evidence, TSF mentions in his book that as a kid he used to go to Denmark, and apparently Kitson was once asked in an interview whether he had been to said country on holiday, to which he replied he used to regularly go aa a kid.
