IBF, WBA, IBO, WBO heavyweight champion Anthony Joshua is backing his former foe, Dillian Whyte, will win very big in less than two weeks.

Whyte is facing former WBO world champion Joseph Parker on July 28th at the O2 Arena in London.

Joshua went to a twelve round decision with Parker back in March, in their unification bout.

And Whyte was stopped by Joshua in seven rounds back in December of 2015.

While Parker became the first man to take Joshua to the distance - the unified beltholder does not expect him to do the same with Whyte.

Joshua is not only backing Whyte to win the fight - he's backing him to win that fight by knockout.

"I'm going with Dillian and I'm going by knockout as well," Joshua told Sky Sports.

"Dillian has got nothing to lose. He's been screaming at world champions saying 'I want to fight here, I want to fight there' and I feel like he wants to prove himself. Parker is strong. Parker can take a shot."

"In my fight he was on the back foot and I boxed clever because I'm trying to set up the next fight with [Deontay] Wilder …but I feel like Dillian has got nothing to lose, everything to gain. He's going to go in there guns blazing and try and knock out Parker ASAP."

Parker has other plans - which include a knockout victory of his own.

At the moment he's ignoring all of the trash talk coming from Whyte, because the Kiwi boxer is very eager to trade punches with him in the ring.

"We want to show that we're the top level and we've made some adjustments and improvements. We're not here to muck around, we're here for war. We've got a great game plan for this fight but if I have to make some changes and throw it out, I'm willing to do that," Parker said.

"He likes to play mind games and he's very good at talking. He tries to say things to get in your head. Sometimes it's rubbish that comes out of his mouth. But I respect him and let him say whatever he wants to say. But when we get in the ring I want to bash him."
