Dillian Whyte has blamed Dereck Chisora for scuppering the chance of a potential rematch after his bitter rival lost to Agit Kabayel.
Whyte, who edged out Chisora in a thrilling heavyweight battle a year ago, was left disappointed by the fellow Londoner's "uninterested" performance and 'The Body Snatcher' admits that a rematch is now almost definitely off the cards.
"He seemed unmotivated, he couldn't be bothered," Whyte told Sky Sports. "Dereck is a strange character, and that shows in his performances. Sometimes he shows up, and other times he doesn't care.
"He's unpredictable. Even he doesn't know what will happen when he wakes up in the morning. You can never bank on someone like that. He might wake up and decide to never box again, or decide to try and become world champion.
"He's blown it big time. There was lots of money on the line in a big event but he's blown it. I'm very disappointed. He's just not ambitious enough anymore.
"We tried to make the rematch back in June but it didn't happen. [Next February] I was expecting to fight Deontay Wilder and, if that fell through, Chisora was the back-up, but now it's unlikely."
Whyte is still hopeful of landing a fight with WBC champion Wilder next, but that matchup could be in doubt after promoter Eddie Hearn revealed that talks are set to begin for a unification showdown between Wilder and Anthony Joshua.
"We will keep chasing Wilder and we will look at other options if he doesn't want it. But I think Wilder will take the fight because we're talking about mega money for him. We'll see," Whyte continued.
"I am the number one at the minute, but I'm not mandatory yet, I may have to fight another eliminator.
"Wilder's got power but he can't box. He's not heavy or weighty enough - you can bully him, throw him around, rough him up. Any time a punch touches his whiskers he wobbles.
"I don't think he's 6'7'', he's lying about that. Fifteen stone is quite light for a heavyweight. When the fight goes longer against big, strong guys then you need weight. Fighting against someone that will push you around, letting punches go, it wears you down.
"I can also box. I have long limbs. I can box him on the outside. Washington, Szpilka and Molina out-boxed him early. I might box him then mid-fight break into a war, or in reverse, I might stand up to him early then box him."
