Anthony Joshua is certain his credibility as a boxer will hit the roof if he ends up beating Wladimir Klitschko at Wembley Stadium.
The unbeaten IBF champion will be facing Klitschko, who is the second longest reigning heavyweight title-holder ever.
Joshua will be slugging it out with Klitschko at the national stadium on the 29th of April.
“I tried to play it down, I’m quite like that – ‘It’s only another fight’,” Joshua told Sky Sports News HQ.
“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.”
