Anthony Joshua is undoubtedly the man to beat in the heavyweight division right now.
The WBA and IBF world champion will meet WBO belt-holder Joseph Parker on March 31, with a fight against WBC champ Deontay Wilder in the pipeline next.
AJ will not want to look too far into the future, as his number one priority must be defeating Parker and making his record 21-0.
The only possible mark against the 28-year-old, and one which is occasionally used as a stick to beat him with, is the calibre of opposition he's faced.
Wladimir Klitschko, the biggest name he has beaten, was 41-years-old by the time they faced off against each other in April last year.
However, despite Joshua's general prestige in the sport, former British fighter Frank Bruno believes there is one man who can surpass him as an even bigger and better champion.
The heir to AJ's throne, according to Bruno, may not be a household name just yet, although he is quickly making an impact on the scene.
Daniel Dubois has enjoyed seven straight knockout victories - with six of them coming before the end of the third round - and has been spotted by Bruno in the process, training in east London.
'Bigger than AJ'
"I think Daniel will be bigger than AJ," Bruno said, via the Daily Mail.
"He is a very, very good prospect and only needs to stay on his game, focused and hungry.
"Daniel is keen, thirsty, eager to learn and a nice, level-headed guy."
The 20-year-old has been so impressive that according to the newspaper, the Board of Control are even considering allowing him to contest the British title, something which is off limits to fighters under-21 under current rules.
While he was expected to fight at the 2020 Olympics in Tokyo, he has withdrawn and instead opted to go professional under Frank Warren.
Judging by his record so far, that was a very good decision indeed. Take a look at what he can do in the footage below:
It's a very bold call from Bruno and only time will tell if he's right.
