Fox Soccer Report, just mentioned Freddy Adu is going to Chivas USA as a DP.
Also, Danny McMahon on FSC doesnt think that Eddie Johnson who was released by Fulham will be able to find a club to play for in Europe and most likely will be on his way to MLS as well.
I think at this point its also safe to say that former Chivas USA goalkeeper Brad Guzan who signed with Aston Villa will be playing in England much longer and is likely to return to MLS. Dude hasnt started a single game for Villa.
UPDATE: Apparently he's decided to go to Philadelphia Union instead of Chivas USA and its not quite known yet wether he will be a DP.
