"I think that was probably the ultimate problem for him here to begin with.
"Boy and man he was brought up at one of the greatest football clubs in the world. It must be a great wrench in your life when you lose that, and that is something he has overcome.

"Gladly, he has overcome that, and I can give him a platform to be as successful at Newcastle as he was at Old Trafford."
