Robert Helenius, who will face Dillian Whyte on Saturday, says his opponent’s temper will be his downfall.
The heavyweight pair will collide before Joshua defends his titles against Takam, and Helenius intends to use Whyte’s temper against him.
Asked about Whyte’s weaknesses, Helenius told Sky Sports: “He loses his temper a lot.
“I’ve seen a couple of his fights. He is a tough fighter. His strength is coming forward all the times – he has good conditioning but I can pick him apart. I am taller and bigger than him.
“I have the reach, the power, and I am fast. It will be a tough fight for both of us. This is a directional fight – it will show who is going up, and who is going down.”
