Dillian Whyte has outlined three things needed to beat Anthony Joshua, but insists Joseph Parker has none of them ahead of Saturday's world title unification fight.
Joshua's impressive record -- with 20 knockouts in as many professional fights -- has few pundits and fighters giving Joseph Parker a chance against the world heavyweight No. 1, with bookmakers having the British fighter as a massive 1/9 favourite to beat the New Zealander at Cardiff's Principality Stadium.
But one man who knows what it is like to hurt Joshua, floor him and beat him is Whyte, who defended his No. 1 position in the WBC rankings by beating Lucas Browne on Saturday.
In his first amateur bout, Whyte beat Joshua on a three-round points decision in 2009. Joshua, who was competing for the fourth time as an amateur, was floored during the bout, that took place above a pub in north London.
They met again in the professional ranks in 2015 when Whyte hurt Joshua early on before being knocked out in the seventh round.
And while Whyte insists he knows what it takes to beat IBF-WBA world champion Joshua, he believes WBO titleholder Parker does not have any of those qualities.
"I think Parker will get smashed to bits," Whyte told ESPN. "I think Parker will be lucky to go six rounds. He hasn't got enough in his arsenal. Parker's strength will be his downfall in this fight. He hasn't got great defence or power and to beat Joshua you have to be one of three things.
"You have to be a very good, talented boxer. Two, you have to be very powerful, and three you have to be super fit and super strong and tough. I don't think Parker is any of them.
"You'll have to soak up a lot of punishment against Joshua at some point and also when you hit him you need to react when he goes into his shell. You saw that against me and Klitschko, when he got hit and thought I don't like this and froze. That's when you have to take your chance. "But Parker will not be able to make him miss."
Victory would earn Joshua a third world title belt and strengthen his argument when it comes to negotiating with American Deontay Wilder, who holds the WBC belt, about a unification fight for all four belts.
But Whyte has plans of his own to fight either Joshua or Wilder later this year. The Jamaica-born contender, who has lived in south London since he was 12, consolidated his position for a title shot in the next year with victory over Australian Browne at the O2 Arena in London and afterwards called on Wilder to face him at the same venue in June.
Whyte, 29, is ranked No. 1 with the WBC, No. 4 with the IBF and No. 9 by the WBO. Only Russia's Alexander Povetkin has a better ranking than Whyte among the chasing pack behind the champions. Povetkin faces England's David Price on Saturday when he will aim to retain his No. 1 position with the WBA and WBO. Povetkin, 38, is also the WBC No. 4 and the IBF No. 5.
