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."
