IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua is not concerned with the statements being made by various critics, who believe WBC champion Tyson Fury is a level above him.

Joshua and Fury are on a possible collision course in 2021.

They have to win their upcoming bouts to make that fight a reality.

Both boxers have defenses lined up for tentative dates in December, with Joshua facing mandatory challenger Kubrat Pulev on the 12th of that month, and Fury defending against Deontay Wilder in a trilogy fight a week later.

"[He] turned professional in 2008 and it took [Fury seven years] to fight for the heavyweight championship of the world. He's on a completely different journey. I want to steam through. I haven't got fear of Fury - whether he's got a better chin than me, a better jab than me, whether he's all of this stuff that people say. So be it. Let me go in there and prove myself. Show you who I am and what I can do," Joshua said to Sky Sports.

"I've fought five champions and been in two unification fights. I'm a two-time heavyweight champion in the space of 24 fights and a [seven-year] career. It shows you I am serious. If Fury is serious, I'll take that fight seriously too."

The only potential hurdle in the way of a Joshua-Fury unification, is a WBO mandatory defense against Oleksandr Usyk.

Usyk is slated to face Derek Chisora in the coming months. Should Usyk win, he would be in line to face Joshua in 2021 - provided Joshua beats Pulev. There is always the possibility that Joshua will vacate the WBO title in order to face Fury with four world titles still up for grabs in the fight.
