Rui Patricio would be my pick following those Euro's, with Tom Heaton also a contender
All the top keepers are locked up at the moment, so we'll have to spend a lot to get one or go for the next tier down (Such as a Begovic)
Forster and Butland are both tied down to long deals, Lloris won't want to leave title contenders for us, Buffon can't have much left in the tank, no way Neuer would trade in playing for one of the biggest clubs on Earth to come to us etc
But yeah, Begovic is hardly the worst we could get and he's better than what we currently have, even if he's not exactly a thrilling signing
