Exeter City manager Gary Caldwell says goalkeeper Joe Whitworth has impressed him since joining the club on loan.
The 20-year-old has agreed a season-long move from Premier League side Crystal Palace and played for the first time in a 3-1 pre-season win over Yeovil Town.
The England youth player recovered from an error that led to Yeovil's goal to save a penalty at Huish Park.

"I think we've seen that with the way he holds himself on the pitch.
