British heavyweight boxer Dillian Whyte has slammed compatriot Anthony Joshua, after revealing he received an "utterly ridiculous" offer from the unified champion for a fight in April.
The 30-year-old claims he's been offered less than he made for his last fight against Dereck Chisora, which he won with an 11th round TKO.
Whyte, who lost to Joshua in 2016, has worked his way back up the rankings, after impressive wins against Lucas Browne, Joseph Parker and Chisora in 2018.
Joshua, the IBF, WBA, WBO and IBO champion, has Wembley Stadium booked for his next fight on April 14 (NZ time), but is yet to confirm his opponent.
Whyte told UK radio station talkSPORT that Joshua's camp wasn't serious about making the fight, after tabling a "silly offer".
"There's been the first offer, but it's utterly ridiculous," he said. "It's way less than what I made to fight Chisora."
"It is a ridiculous offer, they're not serious about the fight. It's ridiculous, the offer comes with other options as well.
"It's silly - I'm a pay-per-view fighter, I've built myself up. It's not like I'm a journeyman, I worked my way up to number one with two governing bodies.
"He needs to take that into consideration. I bring more to the table than even Joseph Parker did and he was a world champion.
"I don't think he wants the fight. There are easier paydays out there for him and he knows I'll bring problems to his mum's house.
"It is a childish offer - if you want to fight, you make a proper offer, you know what I bring to the table.
"Me, Tyson Fury and Wilder - you can't sell out Wembley with anybody else. It looks like Tyson Fury will fight Deontay Wilder, so he needs to stop messing about.
"It's an easy fight to make. I have the rankings, we have history, everybody knows it will be a good fight.
"Nobody will complain about the fight."
If Whyte couldn't fight Joshua, he would consider fighting Wladimir Klitschko, who is reportedly coming out of retirement.
"I'll fight Wladimir Klitschko and knock him out if he comes back, I'll definitely knock him out.
"I know exactly what to do. I trained alongside him, I sparred him for years and I know what he's like - I'd knock him out."
