Wilder responded by dismissing Fury as having had "his time". After beating Klitschko, the 30-year-old remained inactive for over two-and-a-half-years as he struggled with mental health issues and gained weight until reaching an estimated 27 stones, something that could yet undermine him on Saturday.

How he took upon his responsibilities as a champion was up to him. But now it's my time. I've sat patiently, waiting.
"I will knock Tyson Fury out. They say I'm the puncher and he's the boxer, but the same thing was said when I beat (Bermane) Stiverne. I'm going to show you how well I can box. He will go down.
