Eddie Hearn, promoter for IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua, promises to do everything possible to make a unification with WBC world champion Tyson Fury.
Fury captured the WBC world title on Saturday night when he stopped Deontay Wilder in seven rounds at the MGM Grand in Las Vegas.
Hearn has already spoken to Joshua about the fight.
Before he can think about Fury, Joshua is going to have to make a mandatory defense against Kubrat Pulev at Tottenham Hotspur Stadium, likely on a date in June.
And Wilder will likely exercise a rematch clause to face Fury for a third time.
"I've spoke to Top Rank and I've spoke to MTK straight after the fight. Everybody is very clear on this. Everybody wants this fight - Anthony Joshua, Tyson Fury, MTK, Top Rank, Frank Warren, Matchroom," Hearn told Sky Sports.
"There are some hurdles to overcome on the broadcasting, but nothing too much. I promise you this fight will happen. If we have to fight (Kubrat) Pulev, we've got to beat Pulev, and if he has to fight Wilder, he's got to beat Wilder again. Both of those things will happen. Fury will beat Wilder again and Joshua will knock Pulev clean out, despite Bob Arum telling us very differently. You will get this fight. We will do everything that it takes to make this fight.
"Last time, you had us and Team Wilder and we were locking heads. Right now, you have two guys and two camps that genuinely want this fight, that genuinely will do everything that they can to make this fight. It is the only fight. When are we ever going to get the chance of two British world heavyweight champions fighting for the undisputed title against each other? It's never happened before it will never happen again. We'd be clowns, we'd be idiots if we didn't make this fight. We believe we win the fight, they believe they win the fight, so let's see it."
