The 26-year-old, who has three England Under-21 caps to his name, moved to the south coast from Crystal Palace this summer, and made seven league appearances as Wayne Hennessey‘s understudy last season.
He’ll likely be third choice for Allardyce’s first match in charge of England in Slovakia on Sunday. The gloves are expected to be handed to Joe Hart, who joined Torino on loan from Manchester City on Wednesday, with Burnley‘s Tom Heaton acting as his deputy.
