Anthony Joshua and Wladimir Klitschko are aware of what a victory on Saturday night could mean when the pair collide at a packed Wembley Stadium in London.
A massive crowd of 90,000 fans will break the post-war record set by Carl Froch and George Groves in 2014 when Joshua puts his IBF belt on the line and Klitschko brings the vacant WBA and IBO straps with him.
Joshua, who is 18-0 and stepping up to the very top level for the first time, seems unfazed by the task that currently stares him in the face.
“I’m only going to be myself – the fight is already as big as it can be,” said the 27-year-old.
“There’s belts on the line, there’s legacy on the line, there’s 12 rounds of intense, ferocious boxing on the line. It comes with everything you want to see – boxing skills, power, timing. It’s just how long you can last and withstand each other’s abilities.
“I don’t hate Klitschko, I don’t dislike Klitschko, but I want to beat Klitschko. Someone is going to win and someone is going to continue with their career. And I’m very confident that’s me,” he added.
Klitschko, who at 41 is attempting to put defeat to Tyson Fury behind him, is confident he can enjoy an Indian summer at the twilight of his career and regain his place at the summit of the sport.
“This is a big step for AJ,” Klitschko pointed out. “He hasn’t fought this type of quality fighter yet. It’s going to be challenging for him, and it’s going to be challenging for me.
“This fight is 50-50, both fighters have a chance to win the fight, but I have this feeling that this is my night.”
