We all know who is linked with a move this summer - but it's harder to know just how likely the big transfers really are.
So we have used betting patterns to compile a list of transfer probabilities - from dead certs Julio Cesar and Victor Valdes to long shots like Jack Wilshere and Sergio Aguero.
You rarely see a poor bookie and that's because, aside from the occasional clanger, the oddsmakers usually get this sort of thing right.
Here are the latest odds on the main moves, converted into a percentage value - with Uruguayan pair Edinson Cavani and Luis Suarez both odds-on to make multi-million pound transfers this summer.
Odds are given for each player's shortest-priced move, though many are linked with multiple clubs.
