123bet Tyson Fury is adamant that nothing will stop him defeating Oleksandr Usyk when they fight for the undisputed heavyweight championship of the world on Saturday.

Neither man has ever lost a pro fight before. Fury is a rare undefeated, two-time heavyweight world champion - he had to vacate the titles he won from Wladimir Klitschko in 2015 before claiming the WBC belt from Deontay Wilder.

Even against as formidable an opponent as Usyk, who was an undisputed cruiserweight champion before making his move up to heavyweight, Fury is certain he will prevail when they meet, live on Sky Sports Box Office this weekend.

"Why will I win? Because it's what I do. I win, win, win no matter what," he told Sky Sports. "I've always won.

"What I 123bet deliver is victories. Whether it's by an inch or a mile, I deliver every time. Sixteen years as a pro, I've been delivering my whole life. They should call me the midwife because I always deliver."

"I'm sure Sugar[Hill Steward, his trainer] has got an idea for what he wants me to do in the fight. For me, I'll figure it out when I get in there. I've seen many styles before. I've fought orthodox and southpaws, tall, short, fat, thin… I've fought them all," he said.
