Anthony Joshua tells Tyson Fury to stop talking and start training

Fury - who hasn't fought since beating Wladimir Klitschko back in 2015 - was less than impressed with Joshua's performance against Joseph Parker quickly proclaiming himself as 'the true king'

Anthony Joshua has told Tyson Fury to stop talking and get in shape as the two British heavyweights continue to circle each other at the very top of the sport.

Joshua defended his IBF, WBA and WBO titles against Joseph Parker at the end of last month and has now set his sights on unifying the heavyweight division.

Fury - who hasn't fought since winning the WBA, IBF, WBO and IBO titles with victory over Wladimir Klitschko back in 2015 - was less than impressed with Joshua's performance in Cardiff quickly proclaiming himself as 'the true king' on social media.

But Joshua remains unmoved and has called on Fury to get back in the ring if he's to be taken seriously once more.

"After the Klitschko fight, that was a guy I called out to challenge me straight away and I still mention it now," he said. "There is no denying Tyson knows how to box. He is a good boxer.

"But until he makes his return to the ring, I cannot sit down and wait patiently at home for Tyson Fury's return. I have a career and goals I want to achieve so I am focusing on what I am doing.

"When he gets himself together…. boxing fans are awaiting his return. He has to get himself back in action and worry about what he is doing, rather than sitting at home commentating on my fights.

"He should be getting a bit of motivation and hunger back in the belly to get training and get back in the ring because realistically people don't want to see a commentator. They want to see a fighter fight."

A fight against WBC champ Deontay Wilder appears next on the agenda for the 2012 Olympic champion Joshua is upping the ante to try and make that fight happen sooner rather than later.

"I want that fight, no doubt about it. He was very vocal about wanting the fight before I was, because my objective was to accumulate every single one of the belts," he added.

"Now I have done that, Wilder's my 100 per cent attention. We're about to make another offer to Wilder's team - a very good offer that should create a lot of interest from Wilder.

"Hopefully that will stop a lot of his talking and whining, and he can step up to the plate. I don't know about Wilder and how serious he is. If Wilder offered me the deal I'm going to offer him - to come and fight for four belts, with a great rematch clause and a great up-front clause - I would grab that with both hands.

"I would be over the moon with a deal like that, so it will be interesting to see how he takes it."
