The WBC heavyweight world champion returned to social media and took aim at his rivals for refusing to take him on in the ring.
Fury had been due to take on Oleksandr Usyk but negotiations between the pair collapsed and potential bouts with Andy Ruiz Jr and Zhilei Zhang have also failed to come to fruition.
He said: "I've been off Instagram for a while, I've been on holiday, I've been chilling, I've been eating, I've been doing all sorts of s***. But I just wanted to say to everybody that I want to knock out all these m************ out and I'm ready to rumble.
"I've not fought since December through no fault of my own. I've tried to fight some little midget Usyk and he's not wanted, I've tried to fight AJ, he don't want no smoke.
"I've tried to fight everyone. Andy Ruiz Jr has asked for 20 million, silly little b**** don't know where he's got that from. Who's out there? Who's available? Zhang, he was a good little fight but Joyce wants his rematch so that's not happening now. So, I'm looking to fight anybody, any place, anytime, anywhere. anything."
Fury also challenged his promoter Frank Warren to sort out a fight to be held in his native North West England this summer.
He said: "Back in the gym today and here’s my challenge: I challenge Frank Warren to get me a fight in the North West of England anytime soon.
"July, August—whenever you’re ready, Frank, I’ll be ready."
