Frank Warren has vowed to do everything he can to ensure Tyson Fury and Anthony Joshua clash this year.
Fury cemented his position as the best heavyweight in the world with his seventh-round stoppage of Deontay Wilder last weekend.
The four heavyweight titles now reside in Britain following Joshua's revenge mission against Andy Ruiz Jr last year.
Before the undisputed clash can take place, however, Fury must first take on Wilder in their trilogy fight while Joshua will take on Kubrat Pulev on June 20.
But promoter Warren - along with his opposite number Eddie Hearn - has promised the fans the fight they crave.
"There is a clear path for him now set out once he gets the third fight with the American out of the way this summer," he said.

"And that will be towards WBA, IBF and WBO champion Anthony Joshua for an undisputed clash.
"We want that this year once we get Wilder out of the way and if – and that's a big if for me – Joshua beats Pulev in June.
"This week Joshua's promoter Eddie Hearn has been doing plenty of big talk but let's see if he backs up his word.
"This won't be a Matchroom show this will be a joint promotion featuring all parties when we do get round to doing a deal.
"All that really matters is getting the fight on so the British public get to see it – they don't care about promoters arguing and positioning themselves.
"It would be a tragedy for our sport and boxing fans in this country if we don't get the fight on.
"But I promise we will be doing everything possible to make it happen before the end of 2020."
Fury became a two-time world champion with his victory over Wilder having previously ruled the division in 2015 when he outpointed Wladimir Klitschko.
On that occasion, Fury struggled to deal with the fame and fortune and fell into a near three-year drink and drug-fuelled depression.
But Warren, writing in his Daily Star column, insists this time will be different.
"Fury has always been the best heavyweight in the world in my eyes since he beat Klitschko in Dusseldorf," he added.
"But he rid any doubt about it by brutally tearing apart Wilder to become WBC champion.
"When he beat Klitschko he lost the buzz for boxing as he battled booze, addiction and mental health issues.
"But this time he is primed to stay at the top.
"This time he is in good shape both mentally and physically while he doesn't have to worry about finances with his family's future secure.
"But he also still has the drive to succeed more in the sport he reigns supreme in.
"The last time he never got up for a rematch with Klitschko.
"But there will be no problem focussing on a rematch with Wilder that's for sure."
