Tyson Fury has said his long-awaited fight against Anthony Joshua is merely a "stepping stone" for a third clash with Oleksandr Usyk.
Fury and Joshua will meet on Dec.11 in Cardiff, Wales, Turki Alalshikh announced this week, in arguably the biggest fight in British boxing history.
The event will be streamed on Netflix, with the main event set to take place after midnight.
The British pair signed separate deals with Turki Alalshikh earlier this year, but points such as the location of the fight saw negotiations drag out.
With the fight now confirmed, Fury has vowed to stop Joshua in seven rounds before moving on to a fight against Usyk in March.
"I'm just going to knock him out, 100%," Fury said in an interview on his FurociTV YouTube channel.
"I'm going to box the head off him and stop him inside six, seven rounds. I'm only using Joshua as a stepping stone, a warm-up to Usyk. Joshua to me is an old, dossing bum.
"A weightlifter. Too many weights, not enough speed. Too many weights, not enough cardio."
Fury lost twice to Usyk in Saudi Arabia in 2024, via split and unanimous decisions, respectively, for the undisputed heavyweight titles. Usyk also has two points victories over Joshua.
Fury said he wants another shot at the Ukrainian, this time in the United States.
"I want Usyk in America where I get a fair decision. I won the first two fights and I'll get a decision here [America] where it's fair," he said.
