According to IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua (21-0, 20 KOs), he is not frustrated as the negotiations to make a deal with WBC champion Deontay Wilder (40-0, 39 KOs) continue to drag out.

Joshua is going to return to the ring in September.

He was last seen in action back in March, when he won a twelve round unanimous decision over Joseph Parker to unify the four heavyweight belts in Cardiff.

At the moment Joshua has two options on the table.

He can either fight Wilder in a unification or he can face his WBA mandatory challenger, Alexander Povetkin.

There is a deal in place with Povetkin - Joshua says his main priority is to get in the ring with Wilder.

Wilder's handlers offered Joshua a guarantee of $50 million to fight in the United States - and that was rejected by Joshua, at least for the moment, as the British superstar said he's willing to accept less money to make the fight in the UK.

Wilder is open to the idea of fighting Joshua on UK soil - but obviously the monetary terms would have to make sense.

"It's not frustrated, it's just I've spoken about it, I've said my piece," Joshua told Sky Sports.

"I'm still training, but in terms of a three-month camp, we've got until the end of the month, but there's still a few more weeks. It's just the nitty gritty I think.

"Everyone has seen the gold at the end of the rainbow, and everyone wants a piece. It's not a problem, there's enough in the pot for everyone to eat, but just be realistic and that's all it is. There's so many out there for me to box and I've been doing it back-to-back, so it's no problem. Then when I beat Wilder, the next question is - when are you going to fight Fury? The questions will never stop, and I just keep on knocking them down."
