"Instead of making him super fit, they made things too complex. He should have never have lost against Usyk. It shouldn't have even been close, because he is that good. But my voice will only go so far in camp. I just think for that camp, I didn't like what I saw. I just thought this is getting overcomplicated and it came to fruition in the ring.

"He should have just been super fit and made to go do his thing. The standard needed to go up for Usyk. That camp for me was 60 per cent for Fury for the rematch. And he only just come unstuck." Despite hanging up his gloves, Fury has been seen keeping in shape, fuelling rumours of a return to the ring.

This week, the former two-time champion teased an imminent announcement after the heavyweight star hinted at a potential return to the ring. In an video with his father Fury Sr, the 'Gypsy King' said: "Business meeting today, dad. En-route. Incoming, incoming."

I mean, all we see on Instagram is him," he remarked. “Even today, after leaving the press conference, I saw his post – him in hand wraps, sparring a solid 12 rounds.

"Why do this to us? What does it mean? Is this some sort of mind game or is he gearing up for a comeback? Just let us know either way. Put us out of our misery. Look, AJ's got to have a little keyhole surgery on his elbow. He'll be back post-September. It's there, isn't it? Let's just make it happen.

"When we talk about big fights, this fight is the biggest fight, not just in British boxing, in world boxing, by a mile. And I just feel like it's time. This is the moment. We're reliant upon Tyson Fury. We're ready to go, but obviously he's got to be comfortable. He's got to be up for it. He's a competitive so-and-so, and I just know in his mind, he'll want to dance with Anthony Joshua. So, dust those shoes off and let's make it happen."
