The former two-time unified heavyweight world champion, 32, is promising an explosive KO on Saturday night in Jeddah, Saudi Arabia.
Joshua suffered his second career defeat when he faced Usyk at the Tottenham Hotspur Stadium last September, losing the IBF, WBA and WBO heavyweight titles in the process.
But despite that setback it seems that his spirit hasn’t dipped in the slightest as he vowed to make Usyk pay for his comprehensive defeat eleven months ago.
Speaking to Sky Sports, he said: “Previous experiences are helpful but it is about what you do on the night.
“I don’t know how much it will help me but I am focused and I am just ready to get the job done.
“I feel like one of my main strengths is I am a quick learner, I am a sponge but ultimately, aside from all the learning and stuff like that, it is a fight. That’s it.
“Whoever throws the most punches and lands the most punches wins and that is all that matters isn’t it?
“I will do my best, I am just doing my best and that is all I can do.
“We are going knockout.”
Meanwhile, AJ’s promoter Eddie Hearn said he is looking forward to seeing him ‘let those hands go’ this weekend.
Hearn told Sky Sports: “Listen, I am biased and I have been deluded at times but I am a massive AJ fan and I just see a guy putting a lot of pressure on himself and a guy who wants it so bad.
“I see a guy who is punching sharply and it is going to be nervous and who is going to pounce in there on the night.
“I just feel that he is going to do everything right and he is going to let those hands go and if he lets those hands go, I really believe he wins this fight.
“I have said this to him and I have said before, by the time that bell rings at the end of the sixth round I want this fight over or I want Oleksandr Usyk physically in a place that he wishes he will never return to.
“If you let this man get into his rhythm, you have no chance of winning this fight and that is what happened in the first fight.
“The sixth round passed and Usyk gets better and better, he figures you out and before you know it, you see him back in the changing room.
“Get in there, get among it, make it count, make him pay.
“We come to this fight as challengers, AJ has nothing.
“AJ is a bright guy, he is an intelligent guy, he needs to understand how he wins the fight and he does now.”
