Murat Gassiev would welcome a fight with Derek Chisora or Deontay Wilder.
Gassiev holds a WBA 'regular' heavyweight title while Oleksandr Usyk, who beat the Russian in their 2018 cruiserweight clash, is that sanctioning body's 'super' or primary world heavyweight champion.
, and Gassiev would be open to defending his belt against the victor.
"It's a good fight. Before my last fight, at the weigh-in, I saw them face off. But I thought it was like a joke," Gassiev told the Toe2Toe podcast.
"Deontay, a couple of years ago I sparred with him. He's a great guy, great person, nice fighter. He had good power, a hard warrior and it's a good fight.
"My opinion, I think Derek wins this fight by knockout. If after this fight, he's not retired, why not? Or Deontay Wilder, if he wins. It doesn't matter.
"It's just we need to find the best for all boxing fans."
There are other British fighters that Gassiev would relish boxing, Fabio Wardley, the WBO champion, and Daniel Dubois among them.
"Fabio, he's world champion, he's one of the best heavyweights in the world right now," Gassiev reflected. "A unification fight is always an interesting fight.
"Right now is a good time for UK boxing," he continued. "Daniel, again, a big name for boxing, a former heavyweight champion. You never know what'll happen."
He added: "I would love to fight Tyson Fury.
"Big showman, I like his style inside the ring, outside, a lot of respect for him."
Though Gassiev noted: "Before a fight you have plan A, plan B, plan C, a lot of game plans. But when you take some punches, everything changes. One punch can change all.
"With any opponent I try to do my best and do everything to win."
