This one is a bit of a rumour, but I'm not dismissing: it Frank Lampard to LA Galaxy; Landon Donovan to Everton.
Obviously not a swap deal, but MLS teams are only allowed three "designated players" per team.
Galaxy have Beckham, Keane and Donovan.
Donovan is now in the final year of his contract and in a position to force a move from The MLS (who own all player contracts)
Add that to the fact that he's one of American sports poster boys, and he's sponsored by Nike, the same Nike who have just became our kit manufacturers, and you'll see why I think this MAY happen.
Lampard was defo being talked to at that Galaxy game. I lol'd when the press said he was there to watch Beckham.
