Dominic Breazeale has promised to spoil Anthony Joshua and his fans' night on Saturday, as the American goes in search of his first world title at the O2 Arena.
The Californian is venturing outside the United States for the first time in his professional career, and has been in England for the past week, preparing for his showdown with one of the hottest properties in heavyweight boxing, right now.
The 6ft 7in fighter has previously made his feelings known, saying that Joshua has had it easy in the first 16 fights of his career. And Breazeale (17-0-KO15) was also critical of fellow American, Charles Martin, when Joshua secured the IBF world title belt back in April.

The Watford-born fighter will make his first title defence in what is now branded his home - the O2 Arena - but while Joshua's fans have had many enjoyable nights at the venue in recent times, Breazeale says he is ready bring Joshua fans back down to earth.
"It's nice to be here and good to be in London. It's a good place to be right now. They love him (Joshua) here but I am sorry I have had to come over the pond and ruin their day, but it's one of those situations." Breazeale told Sky Sports.
"I've come to win and put on a big show and me and Anthony Joshua are going to fight on June 25 - and I am looking forward to it.
"I am probably the biggest fighter he's fought, 6ft 7ins, 255lbs. I've probably got the same hand-speed, probably a bit more power and I can definitely take a shot.
"It's going to be two gladiators going at it and Anthony Joshua knows that."
The 26-year-old has yet to fight beyond the seventh round, having never gone the distance in any of professional bouts to date, but Breazeale is confident his experience of going this distance will hand him an advantage over Joshua (16-0-KO16).
"I plan on putting on some extreme pressure and taking Joshua to places he's never been. We'll find out on Saturday night if he can handle it." Breazeale told Sky Sports.
"I want him to feel uncomfortable at all times of the fight, every second of every round. Yes, he's got rid of a lot of his guys in the earlier rounds, he hasn't been taken into deep waters. Do I want to see him go into uncharted territory? Of course, without a doubt."
However, while the Californian is wise in his assessments, and knows that knocking out one of the reigning heavyweight champions will be a tough ask, he admits he will take the chance to give Joshua a taste of his own medicine, should the opportunity present itself.
"If I see something I can take in the first, second round I'm definitely going to get him out of there." Breazeale admitted.
Prior to the fight's announcement, it was made clear by Joshua's promoter, Eddie Hearn, that they were to begin making inroads towards boosting the Brit's profile in America, with Breazeale the second consecutive opponent from across the pond, for Joshua.
But Breazeale is not prepared to accept that Joshua is using him as a way of boosting his profile in the Californian's homeland, and is ready to bring the Brit's prolific career record to a halt.
Joshua will be sorry
"I think Joshua's thinking of me as a stepping stone and he's going to be sorry about that." said Breazeale. "He's just wrong. He's fighting a guy at 6'7", 255 pounds that brings the pressure and a great pace from round to round.
"I'm one of those guys that I might take a shot, I might work some defence or I might work a strong jab."
Dillian Whyte has proved to be Joshua's sternest test to date, when the 26-year-old defeated his fellow Brit at the O2, back in December. And with Joshua and Breazeale boasting plenty of experience in sending their opponents to the canvas, it will be hard to believe that either of their immaculate records will not be shattered on Saturday night.
"I'm going in as the underdog, I'm going into an arena with 17,000 opposing fans." said Breazeale. "I've been picked as the smaller guy in the ring, by the IBF as a stepping stone and I feel like my back is against the wall. I'm going to come out fighting."
