It has hardly been a battle of the words between Ukrainian Wladimir Klitschko and Brit Anthony Joshua in the lead up to their fight on April 29 at Wembley.

On the line are the International Boxing Federation (IBF), the World Boxing Organisation (WBO), and World Boxing Association (WBA) titles which were vacated by Tyson Fury at the end of 2016 whilst he underwent medical treatment and recovery.

Quite a haul, eh?

And although it’s been relatively tame on the trash talking in the build up to the fight, Anthony Joshua has been taunted by his opponent after recent comments emerged from the Briton’s interview with GQ magazine.

In the article, Joshua made reference to ordinary people becoming multimillionaires because of assets and property prices which was his original aim when he started as a boxer.

Now, he says: “So the new school of though is that I need to be a billionaire.”

Klitschko has since responded to those remarks on Twitter, taunting Joshua and labelling him “Mr Billionaire.”

Klitschko tweeted a rather tongue in cheek response - "@Klitschko Thumbs up. From now on the nick name was made – “Mr Billionaire” You’ve got to love AJ’s ambitions!"

And, any who had doubts about whether Klitschko is still fragile following his defeat to Tyson Fury in November 2015, who ended his 11 year undefeated run, were quickly reminded by Joshua’s boxing promoter Eddie Hearn.

A columnist for the Daily Mail, Hearn wrote: “This is an absolute must-win for Klitschko and the mental lessons learned from the Fury fight may spur him to try and unsettle Anthony.”

Not only that, Hearn also expects Klitschko to ramp up the heat on AJ during fight week.

"I really feel that Klitschko will turn up the heat on AJ on fight week and do all he can to get in his mind."

Klitschko is training hard and tells Joshua it will be like “facing Mount Everest”

As reported BBC Sport, Wladimir Klitschko said: “I believe this fight is going to be the most important of my career.”

He eluded to a metaphor of climbing Mount Everest which one can only assume is his reference to Joshua’s career moving quite fast and that some might make it, some might not.

He went on to add: “But Mount Everest is still there. So am I.”

And, Joshua should not underestimate the size of the task in front of him. Klitschko has won 64 fights, with 53 knockouts in his 21-year career.

It’s expected Wembley will see 90,000 spectators attend the bout, which BBC Sport claim would be on par with the all-time British attendance record which was set in 1939.

Hold on to your seats…
