Wladimir Klitschko's talkative challenger Tyson Fury has cranked up his vitriol ahead of Saturday's fight in Dusseldorf by telling the world heavyweight champion he plans to make him "look like a child" in front of his own fans.
Klitschko (64-3, 53 KOs) has been world champion since 2006 and starts a betting favourite to make a 19th consecutive world title defence at the Esprit Arena.
But Fury (24-0, 18 KOs), who at 6-foot-9 will have a three inch height advantage as he bids to separate the Ukrainian from his WBA, IBF and WBO title belts, told ESPN he is convinced his first world title fight will be a stroll in the park.
"I'm not going to give the game plan away but what I will say is that I will make him look like a child and this will be an easy fight for me," Fury said. "I will make him look an idiot. I will make him look a fool and humiliated in front of his own 60,000 crowd.
"I will humiliate him before stopping him. I'm not going to points, I'm going to stop him."
Fury, 27, is an interesting character who in the build up to this fight has dressed up as Batman and wrestled with someone dressed as the Joker at a press conference, declared he is considering running as MP in his local area of Morecambe and posted a video of himself smashing a melon with his head.
Klitschko has explained Fury's behaviour as being down to him being bipolar.
On his Twitter account, Fury's contrasting character traits can be seen as he mixes uncompromising declarations of intent with religious beliefs. Fury has also recently been criticised for comments made about homophobia, abortion, Armageddon and paedophillia.
You never know whether Fury is going to be polite and respectful, or raging against the world, and Klitschko in particular.
The unbeaten British boxer says he will have to be just as unpredictable in the ring against Klitschko if he is to pull off an upset.
"You ain't going to win this fight doing one thing," Fury said.
"This fight is going to be won doing many things, changing it up all the time, not giving him the chance to get into his routine or game plan. Changing it all the time is the key and that's what I will do.
"If I have got to go out on my sword trying to win, I'm better off doing that than losing on points, trying to not win and making excuses afterwards. You're better off getting carried out than faffing around."
Klitschko is chasing Joe Louis' all-time record of reigning as world heavyweight champion for 11 years and eight months with 25 defences.
The 39-year-old, who has a child with his fiancée, American actress Hayden Panettiere, has been champion nine years and also held the WBO title from 2000 to 2002.
But he said: "I hear what people say about the record but I don't pay attention to it. It's additional pressure I don't need.
"When I'm done with boxing, that's when I can look back and say, 'That's what I did'."
