Ever since Anthony Joshua got past the tough test that was Joseph Parker on March 31, the boxing world has been clamouring for one heavyweight fight and one heavyweight fight only.Negotiations have been ongoing for months, even before AJ scored a unanimous points victory over Parker at the Principality Stadium in Cardiff, and these protracted talks have been well publicised as well by both parties.Deontay Wilder is the man holding the WBC world title belt that Joshua is craving to take, and it is the belt that would complete AJ's collection and confirm his dominance over the rest of the division.Just days after Joshua posted a tweet signifying that he wants Wilder's championship, AJ took to Instagram to post a video of him watching the Bronze Bomber's last fight, an explosive knockout of Cuban brawler Luis Ortiz, claiming that he was 'studying' his rival.All this comes after Wilder emailed Joshua's promotor Eddie Hearn a '$50 million offer' to make the fight happen, to which Hearn wants to see proof of funds before he agrees to any deal.It is clear to see this is the fight that the hardcore and casual boxing fans want to see, but judging from Hearn's latest tweet, negotiations between the two teams may not be progressing at all.AJ fans may remember the devastating knockout of David Price in the fight before the AJ-Parker bout, and the man who floored Price could be getting a title shot sooner rather than later.Alexander Povetkin was the fighter who shook the Welsh capital when he sent Price sprawling to the canvas, and with that win secured himself as the mandatory contender to Joshua's IBF championship.

And a tweet that Hearn posted today shows the Matchroom Boxing leader pictured with Povetkin's promoter Andrey Ryabinskiy could mean one of two things for the heavyweight division.

On one hand, it could mean talks between Joshua and Wilder have completely broken down, paving the way for the 38-year old Russian to activate his mandatory clause to try and dethrone AJ of one of his belts.

But on the other hand, there is a chance Hearn was negotiating Povetkin's World of Boxing team to hold off on the fight as a deal could be close between Wilder and Joshua to finally clash, with potentially monetary compensation.

If this was the case, Povetkin could face another Matchroom fighter in Dillian Whyte before facing the winner of the super-fight for the IBF belt, whilst another option would be facing the WBA regular champion Manuel Charr.

With Hearn's tweet out in the open though, it will be interesting to see what happens in the next few weeks, and if the mega-fight that most people want to see is still really alive.
