Tyson Fury took the opportunity to call out Oleksandr Usyk after his TKO victory against Derek Chisora at Tottenham Hotspur Stadium.
Victory came in front of the Ukrainian at ringside, who holds the other three heavyweight belts, and it is widely expected that a unification fight is next on the agenda.
There has not been a unified heavyweight champion since Lennox Lewis at the turn of the millennium and such a bout has evaded Fury in recent years, having seen an agreement to fight Anthony Joshua fall away after the pandemic.
Fury has made it abundantly clear on the next step he wants to take in his career, going face-to-face with Usyk in front of the cameras.
"Where's Oleksandr Usyk, the rabbit? You're next, you little b****, you're getting it," he said in the ring.
"15 stone little midget beat a bodybuilder [referring to Anthony Joshua], but I'm not a bodybuilder. I've already beaten one Ukrainian in [Wladimir] Klitschko. Let's get it on. I will end you. What you going to do? You're going to do f*** all.
"I can't wait. All these big fights have been evaded for so long, but they can't run away anymore. They can run but they can't hide."
Fury and Usyk were also joined in the ring by Joe Joyce, with the Gypsy King taking the opportunity to call out his compatriot as a future opponent.
"Why don't us three do a Royal Rumble?" Fury asked. "Big Joe Joyce is here, he's a warrior. Everyone else is scared of you, so if [Usyk] doesn't want it, let's me and you do Wembley.
"I want Oleksandr Usyk next. If not you, Joe Joyce. I've got some hand problems, I've got to maybe have some surgery on my elbow, but after that, I'm open to anyone.
"I had the left done after the [Deontay] Wilder fight, it will take about six to eight weeks to heal. We'll see when we can be ready, we will see when it can be made."
Speaking earlier in the night ahead of the Fury-Chisora fight, Usyk dubbed the potential bout between him and Fury as one that is clamoured for across the globe.
"The whole of Great Britain, the whole world, especially Ukraine, everyone wants to see this fight happen," he told Sky Sports.
