In 1990 Whitington joined Crawley Town, the team his father Eric had been a fan's favourite at some years before. Whitington played in the team that reached the third round of the FA Cup in 1991, losing 5–0 at the Goldstone Ground against Brighton & Hove Albion. He scored 75 goals in 173 appearances which prompted interest from Cyprus club Omonicosia, but they couldn't meet the asking price of £100,000. That was a disappointment, as in the same season they went on to play Juventus in the European Cup. Then in December 1993, Fourth Division Scarborough to pay £50,000 for his services.
Scarborough

Huddersfield Town

Crawley Town (Again)
Whitington's ban for his drugs offence lasted for 10 months and when the ban was completed the only club that showed any interest were his old club; Crawley Town.
