DANIEL DUBOIS tipped Tyson Fury to beat Anthony Joshua – having sparred both the heavyweight champions.
Fury, 32, and Joshua, 30, have verbally agreed a two-fight deal with 2021, as they eye an undisputed title decider.
The clash of styles and opposing personalties makes for Britain’s biggest ever fight – with fans divided on the outcome.
But 22-year-old hot prospect Dubois, gives WBC champion Fury the slight edge against unified WBA, IBF and WBO king AJ.
He told SPORTbible: “Fury at the moment. His skill and his know-how, coupled with his confidence should beat Joshua.
“But it will be a really good fight. I wouldn’t be surprised if it went the other way and Joshua won.”
Dubois shared the ring with Fury when the Gypsy King was deep in depression and as a result overweight – but his talented had not left him.
He said: “He jumped in for one round with me in Bolton, just before I turned pro.
“I was sparring his cousin Hughie and we did a round together – he was really overweight back then, so it was just quick.
“He’s just as slippery as he looks though. He’s a masterful boxer – he’s learned his craft well.”
Dubois earned a name for himself even before turning pro, following rumours he dropped a then-unbeaten Joshua in the gym.
But the soft-spoken prodigy remained tight lipped about the infamous spar, instead honouring the code of ‘what happens in sparring stays in sparring’.
Dubois explained: ” I want to build my own respect now.
“That was before I turned over and it gave me a great launching pad in the pro game – made everyone interested!
“All these promoters suddenly wanted to sign me… ‘Who’s this kid?’ But now I want to build my own respect.”
