Exeter City manager Gary Caldwell says he has been impressed with goalkeeper Joe Whitworth's start to his spell at the League One side.
The 20-year-old moved to the Grecians on a season-long loan from Crystal Palace in July and has kept four clean sheets in eight games.
City have let in just one goal in their last four matches with only Stevenage and Wigan Athletic - who drew 0-0 with Exeter on Saturday - conceding fewer than their six League One goals.
"Joe's been amazing since he came to the club," Caldwell told BBC Radio Devon.
