Boxing promoters and reigning WBC champion Fury revealed this week that a two-fight deal had been agreed for him to face IBF, IBO, WBA and WBO king Joshua in a double-header next year, in what promise to be the biggest fights in British boxing history.

Both men have obstacles standing in their way before the potential unification fight, with Fury completing his trilogy with America's Deontay Wilder - whom he stopped in February to pick up the WBC title - later this year, while Joshua will defend his titles against mandatory challenger Kubrat Pulev of Bulgaria.

However, with a deal between the two Brits essentially agreed, promoters are already lining up a bumper payday for a bout that would command mammoth interest in the UK and beyond. 

The first fight alone could see Fury and Joshua bank up to £100 million (US$125 million) each in a 50/50 purse split, The Times has reported, citing a source.

That would mean a considerable increase on each fighter's last payday, as Fury is understood to have picked up £80 million from his defeat of Wilder, while Joshua netted £60 from his rematch against Andy Ruiz in Saudi Arabia last December, which he won by unanimous decision to reclaim the titles he had lost in a massive upset earlier that year.

While fight fans and money men will be licking their lips at the prospect of a Fury versus Joshua showdown, concerns have been raised over the involvement of alleged Irish mob boss Daniel Kinahan in making the deal happen. 

Kinahan was named several times by Fury in his video post announcing the fights, but is alleged to be the head of an Irish drug cartel, despite not having any criminal convictions to his name. 

Undefeated lineal champion Fury, 31, nonetheless shared his delight at the prospect of facing Joshua, 30, vowing that he would "smash" Deontay Wilder in their trilogy before moving on to his fellow Brit.  

"One problem... I've just got to smash Deontay Wilder's face right in in the next fight and then we go into the Joshua fight next year," said 'the Gypsy King'. 

"The Gypsy King vs. AJ is on for next year,but there is a hurdle in the road called The Bronze Bomber, AKA the knockout king.

"And I will get onto him and knock him spark out and then we will get onto the big fight."
