If we're expecting a fair wedge for Sá (he only signed a new contract a few months ago so I don't see any reason why we wouldn't be) then keepers like Ramsdale should absolutely be on our radar. It's not a position you can fuck around with and take a chance on a punt like Bellegarde who's just 'alright', if we're serious about staying in the league over the next 3-4 years it's a signing we need to get right.
Ramsdale would be a nailed on good signing, even if he is a bit of a clown. He's had a few high profile mistakes and seems to have buckled under the pressure at Arsenal slightly but he was deservedly being talked about as England's #1 not too long ago.
