In just a few weeks history will be made in Riyadh, Saudi Arabia when Tyson Fury and Oleksandr Usyk meet for the undisputed heavyweight title.
Not only is this a moment of boxing history with it being a rare matchup for an undisputed title, the winner will also be the first fighter in the heavyweight division to hold all four world title belts.
A clash between Fury and Usyk is one which has been craved by the boxing world with both men known for their slick footwork and ability to make fights at times look surprisingly easy to win.
With both men considered to be boxing's two best heavyweights, it's proving difficult for those within the sport to provide a prediction.
Now a sparring partner of Oleksandr Usyk, Darren Sealey, has detailed how Usyk could pose some problems for Fury come fight night.
“I think the output and the pace, we are longer so we have that advantage which is great but it also takes us a little longer to get the punch going because we’ve got so much reach," Sealey told Mirror Fighting.
"The pace of ongoing punches and ongoing outputs. Changing the pace and levels with different shots and angles, albeit Oleksandr Usyk or any shorter fighter it can be tricky if they have a really good pace.
“Fury will maybe stay out strong keeping it nice and long but Usyk will take a couple of rounds to work him out like the master that he is and will be victorious.
"I think Usyk will win whether in the later rounds or by unanimous decision. He is the best at it and the best to do it, undisputed at cruiserweight and undisputed at heavyweight in less than a month."
