Boxing fans have already been treating to one great fight this year when David Haye took on Tony Bellew at the O2 Arena in London.Despite the pair being past their best, the build up to the fight seemed to suggest that there was some genuine hate between the two, which would only contribute to the spectacle of the whole event.Bellew came out of the fight on top, though it took him longer than he would have liked to dispose of the former heavyweight champ while he was carrying a nasty Achilles injury.But what thrilled fans was the hate that seemed to exist between them. Over the years fans have got wise to the manufactured rivalry that exists within the sport and will pounce on it whenever it rears its head.And unfortunately for Wladimir Klitschko he found that out the hard way this weekend when he posted a tweet laying into Anthony Joshua, who he will take on in a highly anticipated fight on April 29.Everyone knew from the start that this fight had no animosity to it, as the pair clearly respect each other's achievements and prowess in the ring, highlighted when they announced the fight in the ring at the end of Joshua's previous victory over Eric Molina in December.So when the veteran Ukrainian fighter tweeted a weak, weak barb at the current IBF Heavyweight champ, fans showed that they saw through the facade straight away.He said: "On April 29th I'm going to fight a wannabe billionaire. Fellas, how many wannabe billionaires did you "fight" in your life? I've none."

But he didn't leave it there, he continued by adding: "How many of you 90.000 that night at Wembley and millions around the world are billionaires?"

Embittered by the sudden turnaround by Haye and Bellew after their fight, in which they suddenly seemed to become bezzie mates, fight fans are no longer willing to indulge these attempts at smack talk for the sake of boosting PPV figures.

They took to Twitter in their droves to put the 41-year-old down for this very reason, as well as his poor banter.

For context, he was referring to a comment that AJ had made last year when asked about becoming the first billionaire boxer.

"They said I'm going to be a billionaire boxer? Is that before or after tax? What would I have to make before tax to be a billionaire boxer? Is that gross or net?" he said.

"What would I spend it on? Properties, then you have to leave some in the bank. Pensions, ISAs and bonds, that kind of stuff. And holidays, you've got to have holidays."
