Jarrell 'Big Baby' Miller is accordingly very adamant that he will KO Anthony Joshua, so much, that he has given a round in which he believes he will stun the Brit, and has even gone into detail of the punch that might well do the damage.
Miller will put his undefeated record on the line to fight for the WBA, WBO, IBF and IBO titles against Joshua at Madison Square Garden, which is the American's hometown and backyard.
If Miller was to pull an upset off, then it would surely go down as one of the biggest upsets in boxing history.
However, 'Big Baby' isn't showing any signs of shying away and this is what he had to say whilst speaking to Sky Sports News, as per Boxing Scene: "I don't like to make predictions, but I'm going to knock him out in the seventh.
"Hands down, I've seen it, I've portrayed knocking him out in the seventh round.
"The combination, I don't know what punch I'm exactly going to hit him with. I think an overhand right, left hook to the body.
“But, I do know this, my mental fortitude is way bigger and way better than his.”
Miller, 30, carried on insisting that Joshua will have a long night ahead, and in the process a 'butt-whupping' waiting for him Stateside.
"This is everything, this is the changing point in my life to get to the next level. AJ was saying something before today, 'I'm not looking past him,' he can't think about the future.
"But you don't want to look past anything, you want to focus on that date, you want to focus all your concentration on that man. This is what it's all about.
"I'm not looking past him, but I know once I beat him, I can help so many other people around me, and countries and communities.
"I'm never looking past AJ, he's not going to be looking past me, but boy he's got a butt-whupping waiting for him."
The pair have already clashed at press conferences - Miller confronted Joshua during a DAZN presser in New York and 'Big Baby' reignited fireworks between the pair when he shoved 'AJ' during their media tour.
It's safe to say that preparations for the fight will surely ramp up after this back and forth which is turning out to be personal between the two fighters.
For several months now, Miller has vowed to prove to the world that Joshua is a 'hype job' and how he'll capitalise on the Olympian's frailties.
“We’re going to train for twelve hard rounds, he can’t keep that kind of pace up,” he promised.
“If you notice that whenever ‘AJ’ has got a knockout it's because the other guy tires out a little bit.
“He gets a little beat up in the first couple of rounds.
“I’m aiming to keep that same energy the whole entire fight. Keep the same pressure up for the whole entire fight. I’ve done it before and I’ll do it again.
“(Joshua is) not going to make it to round eight.”
Whether or not predictions like these will get AJ thinking, we don't know. However, it is clear that Miller is doing everything possible in his arsenal to get under the skin of the undefeated heavyweight champion, even this early.
