Croatia's Filip Hrgovic (10-0, 8 KOs) appears to be keen on turning his sparring showdowns with fellow unbeaten heavyweight Daniel Dubois (15-0, 14 KOs) into a full-on professional contest sometime in 2021.
Hrgovic will return to action on Nov. 7 against Rydell Booker after flattening Alexandre Kartozia with a huge one-punch KO in Denmark last month.
Londoner Dubois, meanwhile, has had his planned domestic superfight against Joe Joyce postponed on numerous occasions, with promoter Frank Warren gradually losing hope that the mouth-watering showdown will be able to welcome ticket-buying fans at all when it does finally take place.
Nisse Sauerland, who co-promotes Hrgovic, wouldn't divulge any details of how exactly his charge fared against Dubois in their 2018 sparring, but wants to see them fight for real when the time is right.
"I don't really like to discuss sparring. But the way we see it? Filip is the best heavyweight in the world," Sauerland told Sky Sports.
"We would fight Dubois, no problem, if the terms were right. He still has to beat Joe Joyce, which is a very tough fight, Dubois should not look past it. But we would take the winner of Joyce vs. Dubois any day of the week. I know Filip would be very keen on that fight.
"The conditions have to be right — for a title of some sort. It needs to mean something, but we're game. Let's see if they are up for it.
"We want to progress as quickly as possible at the same time. We won't wait for a Dubois or a Joyce — we believe Filip is far past them talent-wise. They aren't bad fighters but they need to prove themselves against each other.
"We are waiting but we won't wait too long for that kind of a fight. We have our sights set on some very big fights."
Meanwhile Eddie Hearn, the Matchroom Boxing boss who works alongside Sauerland to promote Hrgovic, also really likes the idea of a bout with Dubois.
"Great fight. We've all heard the sparring stories, let's find out if they're true or not," he said.
"Two great young heavyweights, who are both top 10 in the world now."
