Here you will find transfers going back until Summer 2005. Each transfer has been researched to provide the most accurate possible fee and any other clauses in the deal, and the source for this information is stated. I have tried to include co-ownerships for the youth players where information has been available, but where information was hard to gather or not available, those players were not included.

Note that free loan deals have been left out to stop lists reaching silly levels, as these mostly apply to loans of youth players.
