We already have the structure of one of the best sides in the world, sure a sh*te match against Barca is stirring everyone up but 4 players is like a squad overhaul for SAF. Won't happen with the young team we have.
One player will come in if Nani leaves, one player if Carlos leaves. Valencia rumours have good a tad quiet actually. Villa won't come, he's going to Madrid, Ronaldinho? That's some sort of joke I'm sure.
Fergie is a fan of Benzema but he will be very expensive. Eto'o is interesting actually, he could be a very good addition (Eto'o and Berba could be a good strike partnership), but I think it's likely Moneybags City will throw a whole lot of Pounds to go play over there. I doubt Zlatan will be worth the big money he will comand.
While I am throwing a bit of cold water round, I just think it's worth thinking about just how succesful thiis team is, and there will only be one or two changes at this stage.
