Anthony Joshua warns Oleksandr Usik after sharing a terrifying montage video of his most brutal KOs.
The 31-year-old Brit will defend his WBA, IBF and WBO heavyweight belts against the 34-year-old Ukrainian on Saturday.
And AJ is hoping to put a big marker at Tottenham Hotspur Stadium ahead of a possible unification against rival Tyson Fury.
But the unbeaten former cruiserweight champion Usyk has already won against Chaz Witherspoon and Derek Chisora.
However, Joshua is the favorite thanks to his incredible record of 22 KOs out of 24 wins.
And the Watford lad shared some of his biggest hits with fans on Instagram, simply captioning the post: “Goodnight.”
In the video, the clip shows AJ delivering powerful punches to some of the best in the business, including Vladimir Klitschko, Dillian White and Alexander Povetkin.
And after putting himself in prime position for Saturday’s showpiece, Joshua is confident of defeating Usyak in an all-out war.

AJ said: “I feel strong and good. I am mentally and physically strong so I should be able to handle the pressure.
“I feel like I have nothing if I don’t win it. It won’t be the end of the road, but I’m only winning at the beginning here.
“There is no strategy except to win. I will hurt someone or beat them till I get victory.
“Boxing needs this fight and big fights, we’ve been Saudi and America but when I turned pro I wanted to respect British boxing.
