 He made 154 appearances and scored 42 goals over five seasons with the Lilywhites.When City offered him terms of re-engagement at the end of 2005/06, it was discovered that his original contract had been secretly amended in February 2006 by Jez George.The effect was to allow Simpson and two other players (Josh Simpson and Michael Gash) a free transfer at the end of the season, instead of the usual position where City would have been entitled to a fee under the Bosman ruling requirements for players under the age of 24.
