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).
Between those two Wilder is the master of trashtalk, why Fury is more like a clown or a joker. Wilder talks more to offend the persons, while Fury usually turn everything in to joke or to make a laugh on his opponent.
Fury "tasted the canvass" two times (9 and 12 round), but according to one of judge cards, he won the fight by 110:114 score. So these two "tastes" I wont count as a real knockdowns.
