In the last few days, former unified champion Tyson Fury (25-0, 18 KOs) has been verbally assaulting IBF, IBO, WBA heavyweight world champion Anthony Joshua (20-0, 20 KOs) in interviews and on social media.

Fury, inactive since November 2015 when he shocked Wladimir Klitschko for the heavyweight crown, wants to face Joshua in his first fight back.

At the moment, Fury is training for a ring return in 2018 - possibly on a date in April or May.

Fury is still very much out of shape and has yet to secure his license to box from the British Boxing Board of Control.

Joshua views the contest as mere fantasy for the moment, because Fury has not fought in over two years and more importantly the boxer is not in shape.

"That's more of a fantasy at the moment. It's just that he's not fit and he hasn't had a fight. The ball is in his court. We've stayed consistent, we've defended the titles we've won and we've captured more titles," Joshua said to The Daily Mail.

"If Fury was still fit, we would probably be talking about Fury for March. It's not me... I'm definitely consistent and ready to fight anyone."

Fury has been out of ring while dealing with injuries, substance abuse issues and fighting a battle with depression.

Now, the unbeaten boxer is on the road back and hopes to reclaim his seat at the top.

For Joshua, a deal is basically finalized for him to take on WBO champion Joseph Parker in a high stakes unification on March 31 at Principality in Cardiff, Wales.

Besides his upcoming unification, Joshua is co-promoting his first event on February 3rd, when Isaac Chamberlain and Lawrence Okolie collide in the main event. Joshua's promoter, Eddie Hearn, is the lead on the show.

"When Eddie mentioned about the opportunity of being able to sit with him and bring attention using my audience to what these guys are trying to achieve, I said it's the perfect time for it... but what really goes on in order to become a promoter is a whole other pedigree," Joshua said.

"I've been pro now for going on four years so it's way too early to be thinking about that but to have the opportunity and to be exposed to these types of things, I take them with both hands because it's something I could never have imagined.

"Everyone's doing a good job and I think it's impossible to be the best fighter and the best promoter. Eddie cannot be the best promoter and put on his own boxing shows. He's not a world champion. It's a great opportunity and he said it wouldn't take away anything from my boxing so it made sense. It's good for me."
