At the age of 16, Forrester moved south of England to France, where he was to ply his trade for Auxerre, a team with unprecedented success for the size of their town.
Whilst at Leeds, Forrester had two relatively successful loan spells at Southend United and Grimsby Town, however, only managed to bag 9 first team appearances for The Whites, stating he "was not able to consistently perform at the top level".
The Mariners had seen enough in Forrester's loan spell to offer him a permanent deal, and in the 1995/96, his contributions to the club were justly recognised as he received the Grimsby Town Supporters Young Player of the Year award.
Despite this, his goal:game ratio was somewhat poor, which led to Forrester joining Grimsby's Lincolnshire rivals, Scunthorpe United.
Those at the Stadion Galgenwaard obviously saw enough potential in Forrester to take him on under the Bosman ruling, however, once again his spell away from home was short-lived, stating "things never really worked out in Holland.
He was farmed out on loan to Lincoln City and scored 5 goals in 9 appearances, helping them reach the League Two Play-off semi-finals.
His performances whilst on loan at Sincil Bank won him instant respect, and led him to sign a permanent deal for the Lincolnshire outfit shortly after.
Upon his retirement, Forrester remained in Lincoln where he began to coach youngsters, as well as setting up his own company, Community Business Solutions Limited, a firm which specialises in reducing energy bills for its clients.
