Eddie Hearn has insisted it could take as little as two days to complete a deal for Anthony Joshua to fight Tyson Fury in 2021.

Plans for a 'Battle of Britain' have moved full steam ahead after the 31-year-old stopped Kubrat Pulev in the ninth round on Saturday at Wembley's SSE Arena.

It has paved the way for a twin-fight between the two world heavyweight champions from these shores and while an agreement has been in principle since the summer, it could be signed off as early as next week.

Asked how long realistically it would take to complete, Hearn replied: "A couple of days.

"There is no reason we cannot complete the deal and then move on and solve the other problems.

"We need to write to the governing bodies and say yes we have a deal and we will now talk to the various sites and confirm the dates shortly for what I suppose will be the end of May."

There are some potential stumbling blocks, including if Fury is forced to fight Deontay Wilder for a third time and Joshua could be told by the WBO to face mandatory challenger Oleksandr Usyk.

But Hearn insisted: "The only hitch I can think of is Wilder. If the court order the Fury rematch, and it doesn't sound as though they will, then it is out of our hands.

"They talked tactics for about an hour, it was unbelievable," Hearn revealed. "They were talking about slipping jabs, using elbows in a clinch, it just went on and on.

"He asked to come tonight and wanted 18-odd people and we gave them four. He couldn't come in unless he was working so it was great. We got him to do interviews for Sky and DAZN.

"It was quite fascinating really. I think all fighters are in awe of him, AJ was just bleeding information out of him about slipping jabs. AJ is a student of the game. He is getting better but still has a long way to improve."

Fury's jab is notoriously strong and accurate and while it would not be said in public, it could be suggested Joshua was already getting ready for that fight by picking the brains of Mayweather about avoiding such shots.

The 'Gypsy King' took to social media straight after Pulev had been knocked out and said of his rival: "I knock him out inside three rounds."

Matchroom promoter Hearn disputed that prediction, but above all else is desperate to ensure the two fight at the peak of their powers and avoid a repeat of Mayweather versus Manny Pacquiao, which only occurred when both were in their late thirties

He said: "I think AJ will knock him out. Tonight AJ got hit once maybe with a right hand, that was about it. Fury and Pulev probably punch as hard as each other, Fury is not a devastating puncher, but he is a lot better than Pulev.

"It is an undisputed fight, it should be the toughest fight out there, but I've always fancied him to beat Tyson Fury, always.

"But Fury is definitely at the peak of his powers and so is AJ which actually is why it is so great if we get it made because you saw with Floyd and Pacquiao, it was rubbish."
