Tyson Fury and David Haye aren't exactly the best of friends these days.

The pair have been going back and forth for some time, with Haye claiming they still have 'some unfinished business from 2013.'

Haye, 41, was due to fight Fury, 33, in 2013 but pulled out with a week to go after receiving a cut in sparring.

It was then rescheduled for the following year, but the former champion withdrew again the second time round, this time with a shoulder injury.

The Hayemaker's last professional fight came in May 2018 where he was stopped by Tony Bellew in their rematch.

But the former two-weight world champion made a victorious return on his comeback in September of last year in his exhibition contest against his close friend Joe Fournier.

Fury, meanwhile, recently confirmed that it is the 'final curtain for the Gypsy King' after his incredible sixth-round knockout of Dillian Whyte at Wembley Stadium on April 23.

David Haye would consider coming out of retirement to face Tyson Fury

He had previously hinted at retirement after beating Deontay Wilder in November last year.

Of course, as is almost always the case with Fury, you never know whether to truly believe him nor not.

But for the time being at least, it seems he is happily retired as he is currently enjoying spending time with his family.

However, that hasn't stopped fans from wondering what might have happened if they ever fought.

Well, as it turns out, we might just have the answer for you.

Boxing Fight Simulation posted the hypothetical matchup on their YouTube channel a few months ago, using the classic EA Sports 'Fight Night Champion' video game.

And it was Fury who emerged victorious against the smaller, thinner Haye.

After five rounds of competitive action, Haye's virtual stamina started to drop.

The Gypsy King kept on peppering away at Haye's midriff before landing the final blow.

A weary Haye tried desperately to keep his guard up before being caught with a huge left hook which landed flush on his chin with around 25 seconds left on the clock in the fifth.

Haye bravely tried to stay upright but the left put him face down on the canvas and he could not get back to his feet as the referee counted him out.
