Fury has not fought since his shock win over Wladimir Klitschko to become the IBF, IBO, WBA, WBO heavyweight world champion in 2015.

He has struggled with mental health issues and abusing recreational drugs - which eventually led to him losing his boxing licence and world titles.

He is set to have his hearing relating to his suspended drugs ban early next month.

And the 29-year-old is clearly confident he will soon be back in the ring to try and regain his belts.

While Fury himself has admitted he will need to lose a lot of weight before he is able to fight, he has already called out Anthony Joshua and Tony Bellew for potential fights.

Boxing promoter Eddie Hearn revealed earlier today that talks have already been held about Bellew facing Fury, but will not happen until 2018.

And Fury is keen to make a quick return to competitive action and has teased fans with a clip of him working on his speed.

“Working hard tonight with 20oz gloves trying to get my speed up,” Fury said on his Instagram.

“After 2 years out it's a long lonely rd back to physical fitness, mentally I never left, although Rome wasn't built in a day! & good things come to those who wait! 

“Slowly slowly @mtkglobal @bendavison_ @saundersbillyjoe.”
