Anthony Joshua has said that he does not want his victory over Wladimir Klitschko to "define" his career.

Last April, Joshua stopped Klitschko in front of 90,000 people at Wembley Stadium, but the unified heavyweight champion has ambitions to win all four world title belts in the sport's top division.

IBF and WBA champion Joshua meets WBO title holder Joseph Parker in Cardiff on Saturday night, and the 2012 Olympic gold medallist has suggested that he sees the showdown as just another fight in what he hopes to be a long career.

The 28-year-old told Sky Sports News: "One fight doesn't define us - if it did, I would be sitting back on the throne after my Klitschko fight, but I've got to keep on going. And if you take a hiccup in your career, that shouldn't define you either.

"From my 16th fight when I challenged for the world title, every fight has been a championship fight and something to remember. This fight [against Parker] is very significant - it is history."

Whoever prevails in South Wales this weekend is likely to target a clash with WBC champion Deontay Wilder before the end of 2018.
