Personally, I don't think that anyone will be Everton bound. Even Koeman has said that it will be awkward (or some such word) to buy any players from Southampton - it obviously may not stop them but they'd have to spend a big chunk of their oft-quoted £100mill for Forster.
He said he didn't want to start any [more] fights with Southampton. That tells you something about the last couple of months of his tenure.
