Tyson Fury's promoter Frank Warren has poked fun at Oleksandr Usyk for being a 'crybaby' for complaining to the referee in his fights.
Warren and Fury held a press conference on Wednesday looking ahead to the heavyweight unification fight on May 18.
Fury was his usual entertaining self as he likened himself to famous artist Vincent van Gogh while also admitting he has plenty of 'respect' for Usyk.
However, the 'Gypsy King' feels confident he'll see off the challenge from the Ukrainian to become the undisputed heavyweight champion of the world.

That optimism is shared by boxing promoter Warren, who feels Usyk complains too much in his fights and struggles with body shots.
"I've looked at a lot of his fights, going back to his amateur days, and he is a bit of a crybaby when it comes to getting caught in the body," Warren said.
"He cries to the referee a lot.
"For me, that always was an Achilles Heel. That's what it is and he doesn't like it."
He added: "I looked at that before we made the fight with Dubois.
"[Daniel] Dubois definitely hurt him to body, irrespective of what went on, he doesn't like it in the body.
"For me, the biggest exponent of exploiting a fighter's weakness is the professor here [Fury].
"That's what he does. If anybody's gonna exploit it, it will be Tyson. He's got the mental capacity to do that and keep doing what he has to do.

"I genuinely believe Tyson will win this fight in an explosive style."
Dubois faced off against Usyk in August last year and there was controversy in the fifth round when the 37-year-old was dropped to the canvas.

Referee Luis Pabon ruled the punch a low blow as Usyk was given a maximum of five minutes to recover.
Usyk was back on his feet after three minutes and 45 seconds before stopping Dubois in the ninth round.
Warren launched an appeal to overturn Usyk's win afterwards, but Dubois' team were unsuccessful with Fury soon signing up for a two-fight deal.
