Not many about.
If you look at the best of the best - Casillas, Neuer, Hart, Buffon - none of them are going to move.
Plus they have no money...like Inter. Milan take the hit on wages with a low fee, Inter shift the wages off their bill.
Still seems like there should be a middle ground between those top keepers and Cesar. But I guess if they don't have money (which I feel like they've been saying every summer for years now).
