Anthony Joshua says his fight with Wladimir Klitschko could be the defining moment of his career, saying it can 'change the perspective of my credibility within my industry'.
Joshua, the IBF champion, will put his title on the line against Klitschko at a sold out Wembley Stadium on 29 April in what is being described as a blockbuster fight.
The 27-year-old Joshua told Sky Sports: "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.
"That's why I want to do certain things before I get into training camp, because that will be my sole focus no matter the opportunities on the table outside of my training camp.
"This is my goal, this is it. This is the heavyweight championship."
