Heavyweight Champions Anthony Joshua and Deontay Wilder are in progressing talks about unifying their belts in a hugely anticipated bout.Deontay Wilder's co-manager Shelly Finkel claimed they were offered an £8.8 million flat fee for the fight to happen, however Joshua's team denied this.Eddie Hearn who is the promoter for Anthony Joshua denied making the 'Bronze Bomber' this 'take-it-or-leave-it' offer to unify Wilder's WBC Heavyweight belt with Joshua's IBF, WBA, IBO AND WBO belts.Finkel told the Telegraph on Wednesday: "It was a take-it-or-leave-it offer."We will respond ­appropriately in the next day or so with our counter offer. If Joshua is serious, we will take the fight."Deontay wants this fight. He doesn't want anyone else."However, Eddie Hearn has now taken to Twitter to deny those claims from Wilder's side about the apparent offer.

When asked if he had made a 'take it or leave it 20% split offer', AJ's promoter simply replied: "No."

After defeating Joseph Parker in Cardiff last month to secure the WBO Heavyweight belt, it was inevitable that Joshua would next meet Deontay Wilder to finally unify all the belts and find an undisputed Heavyweight Champion.

The first points victory of his career was AJ's third stadium fight in 11 months, for which he attracted a combined crowd of more than 240,000.

Joshua who now has a record of 21-0 now hopes to lure Wilder to the UK, something the American has said he is happy to do for a 60-40 split in AJ's favour.

The two camps are reportedly eyeing a possible two-fight deal that will allow Wilder a rematch in the US, with AJ hoping to make the first clash at Wembley Stadium or Cardiff's Principality Stadium.

When and where this fight will eventually take place, it is sure to provide one of the biggest and most exciting boxing fights of recent years.
