James, 21, who joined Foxes from Manchester United a year ago, admits Fergie will always be the biggest influence on his career.
He said: "Sir Alex believed in me as a young lad. I'll always remember my time there, two bad years with injury and the club supported me.
"He was always asking how I was getting on. I just think he has the knack of making you want to go out and play.
"When I left he wished me the best of luck and told me if I needed any help in the future he was a phone call away."
