Anthony Joshua is ready to take on Deontay Wilder following his historic win over Joseph Parker on March 31, following which, he became the unified heavyweight champion of the world. 

The IBF, WBA, IBO, and WBO champion has now turned his attention to the American boxer, expressing that such a fight "has to happen" for the sport of boxing to reach the next level. 

Wilder accepted Joshua's invitation for a fight to become the undisputed unified world heavyweight champion, but negotiations seem to have stalled due to a disagreement regarding prize money. 

The British boxer has stated that he would be open to a fight "tomorrow" if he was offered $50m dollars and that his team have already made offers to the American's camp. 

"If it is a $100m fight and they are happy with taking 60-40, I'll take 50-50. Give me $50m dollars up front and I swear I'll take that fight tomorrow," Joshua told Sky Sports.

"They're not making offers like that, but they're talking about it, so it's not real. We offered them a lucrative deal and we are just waiting to hear if he's serious or not.

"They like to jump on social media, rather than emailing us back in a professional manner. I don't understand where they're coming from, nevertheless, there's many heavyweights out there that are serious."

Joshua further expressed that this fight is of paramount importance for this generation of boxers and that it must take place. 

He added: "It has to happen. There's not really been many fights in the heavyweight division in history that haven't happened when you're talking about championship level.

"In terms of history, I think that this fight has to happen because it wouldn't be great for this era of boxing if it doesn't happen."

Wilder holds the WBC heavyweight title and is the first American to hold a world heavyweight belt in nine years. 

Both competitors are undefeated, which would potentially make any sort of outcome a significant one.
