Ex-Crystal Palace boss Sam Allardyce has taken the credit for converting Aaron Wan-Bissaka into a right-back.

Manchester United spent £50m on the 21-year-old after a successful 18 months in the Palace first team.

"We converted him into a right-back at Palace, so I know him very, very well," Allardyce told talkSPORT.

"He didn't break into the team when I was there, but he was training with us every day and he always looked the best prospect of the youngsters.

"He's done a terrific job.

"There's big pressure on him, a £50m signing and playing for Manchester United, but he looks very comfortable, I'm glad to say."
