Anthony Joshua believes becoming the first heavyweight in history to hold all four world title belts would put him alongside the likes of Muhammad Ali and Mike Tyson in the pantheon of boxing greats.
Joshua became the unified champion in April when he added the WBA strap to his IBF title with victory over Wladimir Klitschko in only his 19th professional contest.
Following victory over Carlos Takam last month, the unbeaten 28-year-old is on a collision course with WBO king Joseph Parker and WBC champion Deontay Wilder.
And Joshua claims victory over the other two belt holders would put him alongside the best heavyweights in history – including The Greatest of all.
“One hundred per cent because we have done something credible, tangible and we have the assets to prove it. I always say the proof is in the pudding,” he told Dubai Eye 103.8.
“When I negotiate the fight, once it’s done, I’ll announce it. I don’t like to talk about “I’m this, I’m that” when I haven’t got it. So once I have it and I’m on the journey, say the fight is a week away, I’ll say: “I’m on the verge of mentioning my name alongside the greats like Muhammad Ali and Mike Tyson.
“At the minute, I’m a prospect and I know what the future holds but I’ll just a keep a lid on it for now because we still have so far to go.”
