The heavyweight division is easily one of the most interesting in boxing at the moment.
Anthony Joshua has steadily risen to establish himself as one of the greatest in the sport since turning professional, enjoying a close rivalry with American Deontay Wilder, Brit Dillian Whyte and New Zealander Joseph Parker, all while Tyson Fury's comeback threatens to once again redress the balance.
Joshua is currently leading the way, holding three out of four major heavyweight titles in the WBO, IBF and WBA Super champion crowns.
However, the Englishman is under threat from WBC champion Wilder, who he looks set to face at some point in the next year.
Fury will also no doubt be ready to re-assert the sort of dominance that led to a career high in 2015, when he became a unified heavyweight champion.
With such intense discussion over the quality of fighters in the class, even ex-professionals and commentators are in disagreement.
However, when questioned recently by SecondsOutLive, former great Mike Tyson was in no doubt as to his choice for the best heavyweight fighter.
The 52-year-old picked 2012 Olympic champion Joshua, saying that: "Right now, Anthony Joshua seems to be the best out of the whole lot of them.
"He's the bigger, stronger guy, more put together as well.
"More put together as far as his boxing skill is concerned as well.
"I think he is the best fighter out of the lot of them."
Tyson himself was the youngest ever unified heavyweight champion at just 20 years old.
Widely regarded as one of the greatest fighters of all time, Tyson seems to intimidate Joshua somewhat, despite his ringing endorsement of the Brit.
Joshua said that Tyson would have 'battered him' when asked if he thought the two fighters would have been well matched if they had ever faced off in the ring.
While Joshua has a way to go in matching Tyson's incredible span as a unified world champion, the American's words seem to suggest that Joshua is already writing his name into the history books.
