Trafford has just re-signed for Manchester City from Burnley.
Evatt signed Trafford on-loan for Bolton Wanderers during the goalkeeper's previous time at City.
He recalled to City's website: "From the first minute he walked into Bolton Wanderers FC, he just embraced everything and all the special goalkeepers I’ve worked with in my career either as a player or manager, they have an aura about them.
"Some say they’re a little bit crazy, but James was so confident – not arrogant, because there is a fine line between the two – it was just confidence. He works incredibly hard and has a lot of natural talent and attributes.
“We were fortunate to get him, he was probably fortunate to get us at the time, but he was more than worth the risk because during the 18 months he was with us, he blossomed, and it helped him become the goalkeeper he is today.
“Sometimes, in football, it’s about actions and words and some people have a lot to say without anything to back their words up – from day one, James backed his belief up by the quality of his training and performances suggested to me that being City and England’s No.1 was a distinct possibility one day.
“Nothing he’s done so far has surprised me in the slightest – that he’s re-signed for City, that he’s had so many accolades, that he won the Euro Under-21 tournament and that he’s been in the England squad .
“He will be England’s No.1; I have absolutely no doubt about that.”
