English Premier League clubs are involved in a lot of transfers. Most of them are expected—a good player moving to a bigger club or a player everyone knows is unhappy moving to another team is hardly unexpected.
However, sometimes moves come out of the blue, seem to have been dead in the water or are spectacularly expensive. That is when transfers become more memorable, more sensational.
In order to get onto this list, which is in no particular order, the club buying the player has to be a Premier League one, so Cristiano Ronaldo moving to Real Madrid is ineligible.
