David Haye is confident that he can beat compatriot and rival Anthony Joshua despite a noticeable nine-year gap between the pair and a distinct physical disadvantage for the 36-year-old.
The Hayemaker is currently on the road to recovery and full fitness following an Achilles tendon rupture suffered during his highly anticipated fight against Tony Bellew back in March.
A rematch is on the cards as the pair continue talks to set up a potential clash.
However, Haye seems to be more excited by the prospect of fighting Joshua in what could be the "Battle of Britain".
It's fair to say that Haye is past his prime, and at 6ft 3in tall, is three inches smaller than the 27-year-old from Watford.
Despite the glaring disadvantage, the former WBA champion remains confident about his chances.
“I’m working on the comeback at the moment and the plan is before the end of the year," said Haye.
“I would say I will have four more fights, maximum, before I retire for good. I think if I can win a couple of fights and Joshua keeps his titles, me and him can be the biggest fight ever on UK soil next year.
“He knows he is my target, he’s everybody’s target because he is considered No.1."
Haye then continued by discussing the disadvantages he has over Joshua, and that's one thing that is driving him on to wanting the fight in the first place.
“I love the fact that he's 10 years younger than me and three stone heavier than me, three inches taller.
"That for me is a challenge and a challenge that 90 per cent of the population don't think I've got a chance with.
“That's what excites me. Because if you can do that it's like Evander Holyfield fighting Mike Tyson or Muhammad Ali and George Foreman.”
In the meantime, Haye is concentrating on his role as a promoter after announcing the first show under his Hayemaker Ringstar banner set to take place on October 20.
Olympic silver medalist Joe Joyce is top of the bill at the Indigo and will make his debut against former British heavyweight title challenger Ian Lewison.
Haye added: "I don’t think I’ve given him too much with Ian Lewison because I believe Joe Joyce is the future of the heavyweight division.
“Watching him in sparring day-in, day-out I know this guy has all the tools to be the best heavyweight on the planet.”
