Freddie Cunningham, the longtime manager of IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua, believes an eventual deal for a unification with WBC champion Deontay Wilder will involve two contests - one in the United States and one in the UK.
Joshua will make his American debut on June 1, when he faces once-beaten Andy Ruiz at Madison Square Garden in New York City.
Wilder saw action last Saturday night, when he brutally knocked out mandatory challenger Dominic Breazeale in one round at Barclays Center in Brooklyn.
The two sides have made attempts to make a deal in the past without success.
Whatever the financial terms may be, Cunningham believes there will be a two fight agreement.
"I think if the fight is going to happen, it's going to be a two-fight deal whatever, so it's going to be one here and one there," Cunningham said to Sky Sports.
"It makes sense to do it that way. They are both huge names in their territories. Why not give the fans in America what they want and give the British fans what they want, so I think it will happen, possibly both, but I don't know which way around."
But before Joshua can think about Wilder, he needs to impress the public in the United States.
"It starts with the fighting, his style, what he brings to the ring," Cunningham said. "The knockout will be the first part.
"Outside of it, I think it's just being himself. If you're one of those guys that maybe talks the talk you only go so far. You need to be a bit wider and he's got all the ingredients, he's personable.
"I think the American public like him as well. They seem to get on well with him, it's just showcasing who he is. Do everything in the ring, everything exciting there, and he can showcase who he is."
