The United full-back was sidelined for 18 months through injury but is now fully fit again and Ferguson has admitted that a call-up to the England squad would boost the defenders confidence.
"If Gary were to get a call-up for England it would be fantastic for the lad," Fergie told the club's official website.
"I would not be concerned at all.
"I would be really pleased for him because I think it would give him a great boost.
"He deserves it after what he has gone through over the last year and a half. The perseverance he has shown and the faith he has in himself has been tremendous."
"He has been out for 18 months, which is a long time but he is such a determined lad.
"I am sure he would cope with the rigours of playing club football as well as internationals."
