Anthony Joshua described Tyson Fury as "just another heavyweight" and says his rival should consider retiring soon.

IBF, WBA and WBO title holder Joshua has agreed two fights with WBC champion Fury next year to determine the division's undisputed champion.

Joshua first faces a mandatory title defence against Kubrat Pulev at the end of the year, while Fury is set to take on Deontay Wilder for a third time.

Fury won his first world titles in 2015, seven years after turning professional, whereas his countryman needed just three years to make his big breakthrough.

And ahead of their proposed superfights at some point in 2021, Joshua has cast doubt over whether taking on Fury will be the biggest test of his career.

"Fury has been professional much longer than me. He should be looking to retire soon," he 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."

Fury has won 30 of his 31 professional fights and beat Wilder in February to claim the WBC and Ring Magazine titles.

However, Joshua – with a record of 23 wins from 24 fights – is not fazed about stepping into the ring with the Gypsy King.

"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," Joshua said. 

"So be it. Let me go in there and prove myself. Show you who I am and what I can do.

"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."
