There could be a changing of the guard on Saturday night as Anthony Joshua and Wladimir Klitschko clash in their eagerly-awaited heavyweight showdown.
Joshua has won all 18 of his professional fights by knockout while Klitschko is fighting for the first time since his surprise defeat by Tyson Fury in 2015.
Both men won Olympic gold as amateurs and Joshua will hope to forge a legacy similar to the one Klitschko has built over the years.
Mirror Online boxing columnist and world champion James DeGale is predicting fireworks.
He said: “Boxing is all about timing and I think Anthony Joshua is fighting Wladimir Klitschko at the perfect point in their careers.
“Joshua has looked sensational since he turned professional, no-one has been able to withstand his power so far, and even though Klitschko is vastly more experienced, I can’t see him making it into the second half of the fight.
“It is a victory that could signal the start of Joshua’s dominance of the heavyweight division, much like Klitschko did for a decade.”
He’s not the only one excited by the big fight. So here’s all you need to know about the contest…

Quote corner
Joshua : “I tried to play it down, I’m quite like that – ‘It’s only another fight’.
“But emotionally you will always change how you feel about something. I’m going into the stage, emotionally, where this is my defining fight.
“I’ve done what I had to do to become champion, which is great. But when we talk about defining fights, this is one that could change the perspective of my credibility within my industry. That’s why this fight is important.”
Klitschko : “Experience is something that you cannot buy in the shops. You have to gain it through the years. It’s an advantage.
“People could be great in the preparation and in great spirit, and I’ve seen that. But then they crumble like a cookie just a couple of seconds before the first bell, I’ve seen it.”
