Born to a Nigerian mother and a father with Nigerian and British descent, Joshua initially excelled in football before being convinced to box by his cousin at age 18 to escape the lure of the streets.
Fury, 28, has dealt with depression and lost his boxing licence since beating Wladimir Klitschko in November 2015.
"But with Joshua boxing is going to be a whole different ball game and everyone is going to want to watch him fight". "I had actually picked Klitschko to win as I thought this was just some jumped-up young guy from England".
Tyson Fury has vowed to "rid a fraud out of the heavyweight division" in a new attack on Anthony Joshua.
When I went down, I saw his corner and I stuck my tongue out.
Joshua is 19 fights unbeaten courtesy of his stunning 11th round stoppage of Klitschko at Wembley at the weekend, and Fury was watching closely.
"Joshua was massive before the Klitschko fight but that's taken him to another level".
I was talking to him and I told him, "If you let me get through this round, I'm going fuck you up".
He added: "Joshua was supposed to walk right through him as he was old and useless supposedly, but it didn't work like that did it?" "He got hit with a really good shot but he got back up and even though he was still hurt he pulled through".
"It didn't slip away - I just couldn't be bothered no more". You can take a guy with nothing, clean them up and next thing he's meeting the President of the United States or the Prime Minister of the UK. "It's a great leveller".
"The heavyweight division is always about your longevity because I don't know a heavyweight in any era that didn't have a chance of knocking you out in one punch".
"You get two types of people in boxing, the outlaw and the Mr Nice". It is the heavyweights, it is me and AJ, no one else. "And at the end of it, we'll see who come out clear of the gun smoke!" the WBC heavyweight champion said. After the Klitschko fight, nobody is going to want to watch Deontay Wilder or any of those guys.
"I think that if he wants to show that this is the way he wants to go out, like I wanted to do with no regrets, I think he deserves and [has] paid his dues to be able to write the script for how he wants to go out, [rather] than how he went out [against Joshua]". And so, it is very likely that Joshua may need to fight the Bulgarian if he intends to keep his belt.
