According to the interview I watched Fury said that he will knock out Wilder in two rounds. And yes this is one of the best heavyweight match that must watch. I have a feeling that either of the two will sleep on the canvas.
Fury is not a knock out artist, so I don't know if he can really accomplished that in two rounds. Of course, fighters always makes those kind of predictions that they will going to knock out his opponents. Maybe he is just playing psyche war against Wilder. And remember that Fury is the one who tasted the canvass, he was able to get up though (miraculously).
