Anthony Joshua has criticised Tyson Fury for how long it took him to fight for a world title - and claimed his rival should be thinking about retiring.
The British pair currently hold of the world heavyweight boxing titles between them and they've agree to meet in two unification bouts in 2021.
Joshua says he's ready to fight Fury and give him a chance to cement his legacy.
"Fury has been professional much longer than me. He should be looking to retire soon," the IBF, WBA and WBO champion told Sky Sports.
"If he wants to cement his legacy, I'm here and ready. I've built myself into this position. "I'll challenge Fury, I'll challenge Wilder.
"These guys aren't the biggest names that I've fought on my record anyway. They are just another heavyweight. Look at my record. They are not the best fighters that I have challenged. When they are ready, I'm here to fight."
"I came up quick," Joshua added. "That shows I'm ready. These boys 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.
