WBA, WBO, IBO, IBF heavyweight champion Anthony Joshua (21-0, 20 KOs) is tired of the constant talk that is coming from the direction of Tyson Fury (25-0, 18 KOs).

Fury has been inactive since November of 2015, when he traveled to Germany to pull off the upset of the year with a twelve round decision win over Wladimir Klitschko to win the WBA, IBF, WBO and IBO world titles.

The boxer then underwent some personal problems, as he fought depression and substance abuse issues and lost his titles, one by one.

Fury has regained his license to box, hired a new trainer, and settled an outstanding problem with UK-Anti Doping.

For several months, the former champion has been dropping verbal bombs on social media - and most of them have been focused on Joshua.

But Fury has yet to return to the ring and there is no return date in sight.

Joshua wants Fury to stop wasting everyone's time with his internet outbursts - and instead focus his energy on actually fighting in the ring.

"After the Klitschko fight, that was a guy I called out to challenge me straight away and I still mention it now," Joshua told Sky Sports News.

"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."
