It wasn’t long after David Haye pulled out of his fight against Tony Bellew that Tyson Fury logged into Instagram.The Gypsy King sent a video message challenging Bellew to a contest in 2018.

“I will be ready and willing and waiting to fight Tony Bellew - May 5th, O2 Arena, London,” Fury said.“Like I said before Tony, if you want to fight a real man and the best heavyweight in the world then we’ll be ready and waiting.”Typical Tyson.The former heavyweight champion would go on to tweet a video of himself working out in the gym, showing off the five punch combo he will use to finish off Bellew.

It’s not the first gym video that Fury has posted in recent weeks as he continues his comeback to boxing.

Boxing fans have been rather impressed with the 29-year-old’s movement and speed, especially given his current weight of 25 stone.

What Billy Joe Saunders thinks of Fury in the gym

Indeed, WBO middleweight champion Billy Joe Saunders believes Fury is currently looking as deft as a middleweight right now.

“Whoever Tyson trains with, when he’s on it, there’s not a heavyweight to beat him,” Saunders told iFL TV. “He’s just too fast.

“If you look at him on the pads now, come on. He’s out of shape. There is no fitness there but just look at the speed, look how he’s moving.

“He’s moving like a middleweight and that’s hard to find. That is hard to find and if he puts his head to it this year, gets his weight down, I believe by the end of 2018 he’ll have everything back.”

Saunders is, of course, referring to the WBO and WBA belts that Fury relinquished in 2016 as he dealt with drug and mental issues.

He hasn’t fought since beating Wladimir Klitschko two years ago but there are many who believe that, if he loses weight and gets focussed, he can down Anthony Joshua should the pair meet next year.

That is the bout everyone wants to see. Two unbeaten Brits going head-to-head, with Joshua putting his WBA, IBF and IBO titles on the line - it really doesn’t get much better than that.

Although Deontay Wilder and Joseph Parker will both have a part to play in what figures to be an exciting year in the heavyweight division.
