^ Well Lambert is already a Liverpool player now (signed for 4 million ish - he had his medical before the Peru game). Lallana looks like going there as well for 30 million almost being tied up and Shaw is set for United for the same price.
Schneiderlin I have heard less about, but now his in the French squad someone must go in for him. I think he might be the best of the bunch, but in a less glamorous role. There was talk of trying to get him to switch to playing for England, but that is over now. The other one looking set to leave is Dejan Lovern as well, going to Liverpool as well last I heard.
Still there are a bunch of younger players to step up at Southampton (Chambers, Ward-Prows, Reed) and Jay Rodriguez, who would have been in the England squad, coming back from injury they can still do well. It just depends on who they get in to manage them and how they spend the 70 odd million quid they pull in from transfers. No doubt they will turn out another insanely talented player next year as well.
