1. DEONTAY WILDER
With all but one of his 33 wins coming early, this 6ft 7in WBC king has the power to worry anyone in the division.
2. TYSON FURY
The improving, maturing Wilmslow traveller’s 6ft 9in, 260lb frame means he would match up well physically to the Ukrainian.
3. BRYANT JENNINGS
Was a big underdog when he fought Klitschko earlier this year but he perfored better than expected and he has received a real old-school fight education in his Philadelphia hometown.
4. ANTHONY JOSHUA
A superb physical specimen, Watford’s 2012 Olympic champ is still a couple of years away from a world title challenge.
5. JOSEPH PARKER
This 23-year-old, 6ft 4in New Zealander is developing quickly, although he’s feasted mostly on veterans so far.
6. SERGEY KOVALEV
The Russian rules the light-heavy roost, but if he could carry his power with him up into the heavyweights, who knows?
7. CHARLES MARTIN
This 28-year-old Missouri southpaw has slipped under the radar but is world-rated (WBO no. 4, IBF no. 9) and is unbeaten in 21 (one draw).
8. TAISHAN DONG
He’s had only three fights, all against nobodies, but who wouldn’t be worried by a 7ft tall Chinese heavyweight?
9. DOMINIC BREAZEALE
This former gridiron football player has the build (6ft 6 1/2ins, 256lbs) but must learn how to be ruthless in the ring.
10. MAGOMEDRASUL MEDZHIDOV
If Azerbaijan’s double World amateur champion were to strike gold in Rio next year, why not take the plunge into the pros?
