Mansfield boss Nigel Clough admits he wants more from Manchester United goalkeeper Nathan Bishop.

The 22-year-old goalkeeper was in the Mansfield side that caused the 3-2 FA Cup upset at Doncaster Rovers, though Stags boss Clough wasn't overly impressed with his performance.

"The only one I'm disappointed in at the moment is Nathan Bishop because I think the ratio of goals he's conceding at the moment to the number of shots he's having is incredibly high," Clough said.

"I'm not quite sure how he's not keeping clean sheets."
