Anthony Joshua

Deontay Wilder believes Joseph Parker has one big advantage over Anthony Joshua

The highly-anticipated bout will see Joshua and Parker put their IBF, WBA Super, IBO and WBO belts and unbeaten records on the line, as both fighters aim to become the first undisputed heavyweight champion since Lennox Lewis in 1999.

Many pundits out of the UK believe Joshua's size and skill will prove too much for Parker at the Principality Stadium on April 1 (NZ time), but Wilder has a different perspective.

Speaking to Andrew Gourdie and Jim Kayes on RadioLIVE's Sunday Sport, Wilder issued a warning not to be deceived by the Briton's chiselled physique.

Record sales as more than 70,000 tickets already sold for Parker v Joshua

Tickets went on general sale for the fight at Cardiff's Principality Stadium at midnight on Tuesday (NZT) and within five hours there were only a limited number of $571 and $1142 tickets remaining.

Promoter Eddie Hearn revealed on his Twitter account that the three cheapest categories had sold out in just over an hour after they had gone on sale.

The March 31 fight is sure to sell out with the stadium holding 78,000 under its retractable roof.

Joshua-Parker set for March 31

The Briton's promoters have confirmed he will put his IBF and WBA belts on the line against WBO champion Parker at Cardiff's Principality Stadium, ending months of lengthy and protracted negotiations between both camps.

Both men will put undefeated records on the line, while the victor will move a step closer to unifying the heavyweight division for the first time since Lennox Lewis achieved the feat in 1999.

Anthony Joshua demands Joseph Parker fights him in Britain

The location of the highly-anticipated unification bout remains one of the key points to completing negotiations for the heavyweight division's super fight.

Joshua confirmed the fight deal was 95 per cent over the line for a clash early this year.

Parker's promoter David Higgins is having the contract examined by legal experts and is likely to fly to London late this week to sign it off.

Parker could join him in the UK for a press conference the following week.

Parker taunts fire up Joshua

WBO champion Parker is desperate to fight WBA and IBF champion Joshua and the big Brit believes a March or April bout in the UK is "realistic".

It seems Parker's unorthodox methods of prompting Joshua into taking the fight are hitting a nerve.

Team Parker have released videos to question Joshua's "glass chin" and repeatedly accused him of greed as the Kiwis haggle for a 35 per cent cut of the net profit from what would be a mega-fight.

Joshua has tried to steer clear of the trash talk though he admits there is a place for the "gutter" element of boxing.

Wladimir Klitschko backs Anthony Joshua to beat Joseph Parker

Klitschko, who retired after being knocked out by Joshua in their April fight at Wembley, says he is comfortable with his decision to step away from the boxing ring and believes Joshua is the fighter to carry the glamour division forward.

"I have passed the torch to the younger lion," Klitschko told The Sun.

"I wish, from the bottom of my heart, he continues to carry this torch for a long time and is very successful just like I was. Joshua is capable of unifying the division, absolutely."

Joseph Parker: How I can beat Anthony Joshua

WBO champion Parker is in negotiations with IBF and WBA champion Anthony Joshua for a blockbuster bout in Britain in late March.

Talks have been long and difficult but Parker says they are now "very close" to making the fight a reality.

Parker is already working on a game plan and laying the foundations with his current fitness camp in Auckland where weight loss is a key as he tries to regain the speed that set him apart. 

Anthony Joshua ready to overpay Parker

Joshua's promoter Eddie Hearn finally seems willing to concede some terms to Team Parker to get the fight done, confirming Cardiff's 78,000 seater Principality Stadium is the most likely venue for March.

"We're close," Hearn told Sky Sports UK. "We're at a stage now where we're having to compromise on certain points that we don't really want to, but ultimately we're going to have to because if you want to fight Anthony Joshua, these guys - they want to be overpaid.

Joshua-Parker fight close

WBA and IBF heavyweight champion Joshua is poised for a blockbuster 2018, with bouts against WBO title-holder Parker, WBC king Deontay Wilder and the unbeaten Tyson Fury all potentially in the offing.

Parker looks set to be Joshua's next opponent in a unification clash, though negotiations have not gone entirely smoothly, with the Briton's camp angered by a media conference staged by the 25-year-old and his team.

Promoter David Higgins, Parker and his trainer Kevin Barry explained why he would defeat the owner of the WBA and IBF straps, who they dubbed 'Glass Jaw Joshua'.

50-50 or we don't fight - Wilder wants split Joshua purse

WBA and IBF heavyweight champion Joshua is 20-0, all by knockout, following his win over Carlos Takam in Cardiff in October.

Last month, Wilder retained his WBC crown by flooring Bermane Stiverne in the first round to move to 39-0, and Joshua's promoter Eddie Hearn reportedly held talks with the American's representatives about a potential meeting next year.

Joseph Parker, the WBO champ, is also in the mix for a unification bout with Joshua in 2018, and the New Zealander is happy to settle for a 35 per cent share of profits - a notion Wilder will not entertain.
