Eddie Hearn, promoter for IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua, was very impressed by what he saw on Saturday night.
WBC world champion Deontay Wilder demolished mandatory challenger Dominic Breazeale in a single round at the Barclays Center in Brooklyn.
Back in 2016, Breazeale lasted seven rounds with Joshua, who was making his first defense of the IBF world title.
Joshua is back on June 1, when he faces Andy Ruiz at Madison Square Garden in New York City. The fight will be Joshua's debut in the United States.
Should Joshua come away with the win, and most expect he will, Hearn is crossing his fingers that a Wilder fight will come off next.
"That was an impressive win for Deontay - he's exciting to watch," Hearn told Sky Sports.
"He has taken care of business, now AJ needs to do the same against Ruiz Jr at Madison Square Garden on June 1. The fight with AJ and Wilder is the biggest fight in the sport and all being well in two weeks' time it must happen next - no excuses, this is the fight that will change the sport globally.
"It's a legacy fight and AJ wants it so bad. Two big, fast, dangerous and fearless world heavyweight world champions that can turn the lights out with a blink of the eye - it's a must. First things first, taking care of business on his American debut on June 1 and send a message straight back."
As previously reported, Wilder may very well be ringside for Joshua's U.S. debut.
"I've got a lot of obligations to fulfil," said Wilder. "But if that date is open for me, you may see Deontay Wilder there.
"When it's a good scrap, a good fight that people want to see, you might find me there. I can't say right now, I can't promise you that but when that time comes we'll see what happens."
