British boxer Dillian Whyte has come out firing, saying he would "knock out" WBO world champion Joseph Parker.
The Jamaican-born Whyte was covering Parker's fight against Razvan Cojanu with Sky Sports UK and said he was not impressed with the Kiwi's performance in the ring.
The 29-year-old will be fighting Mariuz Wach in June, and wants to go head-to-head against Parker later in the year.
A win for Whyte could mean he will be in the mix; however, Hughie Fury currently holds a mandatory challenge card.
"If I fight Joseph Parker I believe I will knock him out and become the WBO champion," Whyte told Sky Sports.
"I say that from my heart and from deep in my soul. I honestly believe that. I will knock Joseph Parker out and become WBO champion. I don't see anything there that worries me at all.
"Joseph Parker is a big fish in a small pond. He has said he wants to come to the UK and make a name for himself, so I think I'm the perfect fight for him."
Another British boxer, Tony Bellew, has lashed out at Parker on social media, saying he could end Parker's reign as champion very quickly.
Whyte hit back at Bellew's comments, saying he must wait in line.
"People keep talking about Joseph Parker versus Tony Bellew, but they need to forget that; it's [all about] Joseph Parker versus Dillian Whyte.
"I've tried to get a fight with Tony Bellew; he doesn't want it. Tony Bellew doesn't want to fight a proper heavyweight.
"They need to forget about Tony Bellew - push him to the back of the queue.
"Me versus Joseph Parker is the only fight the UK fans want to see right now. Look at social media; that's all they are talking about - Dillian Whyte versus Joseph Parker."
Parker successfully defended his WBO title for the first time with a unanimous decision win over Cojanu in Manukau on Saturday night.
