10. 2003: Christophe Dugarry (Bordeaux to Birmingham City, loan)
Recently inducted into the Blues' hall of fame, the Frenchman scored five goals in his first half-season to save Birmingham’s debut Premier League season. He joined on a free that summer but was gone by the following February. You may ask how a striker with six goals in 30 games can get into Birmingham’s hall of fame, but it’s either him or Peter Enckelman.
Honourable mention: Jimmy Bullard (Peterborough to Wigan, £275k)
The original prankster’s first three years at the Latics included two promotions after first getting his break at Peterborough under Barry Fry, from whom we assume he learnt his mischievous ways. He has since buzzed around different clubs without settling, while Wigan have been boring ever since.
