Dillian Whyte has blasted Anthony Joshua's 'bizarre' performance against Oleksandr Usyk and called his bitter rival 'a f------ weirdo'.

Whyte (28-2, 19 KOs), 33, has never been one to bite his tongue. 

And he has decided to fire a fierce salvo at former two-time heavyweight champion 'AJ' after he lost the belts following his shock defeat to Usyk this weekend.  

Last night, Joshua was given a painful boxing lesson by the Ukrainian southpaw, who just seemed to be at least one step ahead at every point in the fight. 

He and Usyk battled to and fro on the ropes before the final bell rang to mark the end of the fight, with Whyte saying that, had it not been for the referee, he believed his fellow Brit would have been stopped on his feet.   

"I thought Usyk should've won by TKO in the last round," Whyte told iFL TV.

"I thought they gave Joshua way too much time.

"He just sagged on the ropes and stood there and didn't do anything.

"I thought Usyk deserved a TKO victory.

"I was surprised the way the fight went, I picked Joshua to win in seven rounds because I thought he would enforce his size and pressure and sheer bulk and athleticism and punch power, but he didn't."

Whyte, 33, went on to say that he can't understand why Joshua didn't want to engage in a firefight with Usyk in the first place.

In fact, he felt he was being far too cautious for his own good right from the get go.  

He added: "He was very reserved, tentative, it was weird, I don't know.

"It was weird, it was like the Andy Ruiz performance all over again, like his mind was absent, it was weird.

"He fought a lot more aggressive because Joshua allowed him to be. Joshua kept on stinging him and wasn't following up and every time he stung him Usyk stood in front of him and started throwing hands and Joshua was just letting him do it.

"It was like, can't you see you've hurt him? You hurt him with the right hook, you hit him with the straight right hand, what are you doing? Joshua hurt him and just backed up.

"I didn't get it. I'm still a bit baffled to be honest. It was a bizarre performance from Anthony Joshua but Usyk performed good."

"Joshua is a strange guy, man, I don't know," Whyte replied when asked how Joshua should approach a second fight with Usyk.

Eddie Hearn has confirmed Joshua will exercise the rematch clause in his contract to take on Usyk for a second time. 

"He's a f------ weirdo, he's a weird guy, he's a real proper f------ weirdo, I don't know, weird guy," he insisted.

"Why is he waiting till the second fight? He should have been putting the heat on him.

"Even in the latter stages, okay, you're eight rounds down, you feel like you're behind on the scorecards, start having a go. You're the unified heavyweight champion of the world!

"Maybe he's trying to be a three-times heavyweight champion of the world."
