Former unified world champion Tyson Fury (25-0, 18 KOs) believes WBA, IBO, IBF champion Anthony Joshua (20-0, 20 KOs) has been overhyped.
Fury is even worried that Joshua will get knocked out in a potential unification with WBO champion Joseph Parker - which is being negotiated for the first quarter of 2018.
"That is a risky fight for Joshua, and it could ruin a big fight between us if he loses," Fury said to Gareth Davies of The Telegraph.
Fury has been out of the ring since shocking Wladimir Klitschko to capture the heavyweight crown in November of 2015 in Germany. It was a massive upset at the time, with Klitschko suffering his first defeat in a decade.
Fury would eventually vacate his titles to focus on his mental health, and then lost his boxing license after admitting to substance abuse issues.
But next month the British Boxing Board of Control will hold a meeting to discuss Fury's request to reclaim his boxing license.
Fury is back in training, losing weight, and preparing to fight again by April of next year.
The ultimate goal for him is a showdown with Joshua - arguably the biggest fight on UK soil.
And while some believe Joshua's power and size will be too much - Fury expects to put on another dominant boxing performance.
Fury says he is motivated by the critics who believe he won't stand a chance with the new kid on the block.
"Joshua has been a good little polisher boy, polishing up my belts. He is a big strong lad, good power, good physique, but what else can I say? There are levels to this game, and my boxing ability is way more advanced than his is.
"What will they say when the big fat Gypsy King gets in there and makes this Adonis Joshua look like a child in the ring? They'll say he fought me too soon, that he was inexperienced, that he slipped. But you'll see it some time sooner or later."
