Fury faces the first acid test in his comeback after a two-and-a-half-year absence when he challenges WBC heavyweight champion Wilder, who has won all 40 of his professional contests, 39 inside the distance.
The unbeaten Fury announced that former two-weight world champion Ricky Hatton and Roach, one of the most renowned boxing coaches in the world, will supplement the work of head trainer Ben Davison on December 1 in Los Angeles.
Wilder, though, believes the one man Fury should have in his team is his uncle Peter, who no longer trains his nephew but did so when the Briton stunned Wladimir Klitschko in November 2015.
"This is the biggest fight of his life to date so if I were him I would be trying to reach out to as many resources as I possibly can myself," Wilder said.
"I would have been to see Peter, that's who he really needs because his only fame to this game is beating Klitschko. Peter was the one who was with him for that and Peter knows him in and out.
"When you have your original trainer that knows you and has been with you from day one and you start picking time with other trainers and seeing who's going to be the best, but they don't know you.
"In this short period of time a person isn't going to get to know the whole of you, especially in this fight game because your style is what it is - it was created by someone else, another trainer.
"So when you start getting multiple trainers, for that seems nervous, that's a nervous behaviour for me."
Wilder wants the best version of Fury at the Staples Center after admitting his growing annoyance at those undermining his record in the paid ranks.
He added: "I want him to be comfortable and get the trainer that he feels is going to be able to get the best out of Tyson Fury, I want the best Tyson Fury that we can possibly get.
"I'm already getting excuses now, every time I fight I get excuses and I'm so sick of it, I'm tired of people making excuses for me, I'm tired of people trying to paint out a narrative that isn't it.
"I will knock him out, I will beat him. He says there's not a man from a mother's womb that's going to be able to beat him, then why is he switching up all these trainers then?
"In that case it should be natural but I'm going to show him natural ability."
