Lawrence said: "He's a good professional and he will be good cover for us. When he gets his chance it's up to him."

"Lennie has spoken to Sir Alex Ferguson and we're now waiting for Luke to agree to the deal," said a club spokesman.
Chadwick broke into United's first team during the 2000/01 campaign and he played 16 Premiership games that season, scoring two goals.
