Following a troublesome childhood, Joshua's journey to stardom has drawn comparisons to Tyson, who endured hardships during his upbringing before becoming the youngest heavyweight champion in history when he beat Trevor Berbick in 1986, aged 20.
Tyson admitted he knew little about Joshua before the fight but insisted that he exhibited all the qualities necessary to be a long-serving champion. That is what makes boxing big, it is the heavyweights.
"He's a nice guy but he's got to stop being a nice guy soon", Tyson told ESPN. They won't pay for it, they want the best and the best is Joshua.
Fury has sparred with Joshua in the past and added: "I always said Wladimir would be my easiest fight".
By the end of the round, Kltschko had Joshua in trouble after landing a powerful left hook that rocked him, and in the following round he dropped Joshua with a crushing right hand. And Klitschko, you've got to give credit to him.
"The best man won tonight, and it's an awesome moment for boxing", Klitschko said in a post-fight press conference.
"I'm out here for the foreseeable future, running, doing circuits, padwork, sparring", said Fury, who told www.britishboxers.co.uk that a match-up with Joshua had been pencilled in for April 2018.
"But Joshua's not only athletic, not only has skills. when you're athletic, you've got skills and you've got the chin to take the biggest punch like that, it shows that he can take a punch and get up and restructure his mind and his body and his soul and come back".

Titled " First 100 Days , ' the highlights Trump's initial achievements in office and blasts 'fake news" for downplaying them. He says that in contrast, his administration has been delivering for the American people every day.
"I think certain athletes in any sport get a pass to go out the way they feel".
"It's hard to stay [nice], believe me", Tyson said, claiming Joshua will soon ambandon his ambassadorial image without even realising it. You're going to be financially challenged, scholastically challenged.
With his transcendent appeal and ferocious physical attributes, the Olympic gold medallist leads a pack of hungry heavyweights with names like Fury, WBC title holder Deontay Wilder and WBO champ Joseph Parker all potential opponents.
"I can be the best Tyson Fury again, it didn't slip away, I just couldn't be bothered no more, it was s*** and I didn't value it, but now there's £30m involved".
Boxing superstar Deontay Wilder has a message for Anthony Joshua - LET'S DO THIS!
