The eight-round fight between Paul and Joshua will take place on December 19 in Miami.
"Joshua is one of the best heavyweights in history, but it is always challenging for large fighters like him to face opponents who are smaller and faster. I just need to be careful and focused all eight rounds to avoid his powerful punch. And I believe I can do it. I also believe I will knock him out somewhere in the late fourth or fifth round. After that, I will go for a fight with Fury because I want to face the biggest and strongest. I know what I'm capable of; I will shock the world," added Paul, who is already ranked 14th in the WBA rankings.
