Dereck Chisora has accused Dillian Whyte of "running away" from a heavyweight rematch.
The British rivals shared a memorable battle at The O2 in December, with Whyte claiming a split decision victory which prompted immediate calls for a second fight.
Whyte, who has named a date in June for his next fight, suggested he would rather pursue a world title, unless a rematch with Chisora makes 'financial sense.'
But Chisora questioned whether Whyte genuinely wants to face him again and dismissed the Brixton man's bid to become a world champion.
"The latest is that boy is being a punk, he's running away," Chisora exclusively told Sky Sports. "He's overpricing himself. We've offered him the money and he's priced himself out.
He says he's going for a world title. I don't see it, because there is some unfinished business here.
"He says he's going for a world title. I don't see it, because there is some unfinished business here. Who is he going to fight for a world title? Whoever he fights, he's going to get knocked out."
'Del Boy' admits he could switch his attention to another rematch against Robert Helenius, who received a controversial points victory over the north Londoner in 2011.
"Simple facts are, if he doesn't fight me, then I'll sort a deal with Robert Helenius for the rematch in Finland," said Chisora. "See how that goes, if the numbers add up, we'll do that fight.
"Come back and we'll do Dillian, if he wants to. Who doesn't want to see Dereck Chisora fight?"
The 33-year-old has offered his services as a sparring partner for Tony Bellew and hopes his friend can pull off an upset victory over David Haye on March 4, live on Sky Sports Box Office.
He said: "I sent him a message and said 'listen, if you need to do rounds with a real heavyweight, then call me.' I'll come round and help. He goes: 'yeah, cool'.
"He's my buddy, he's just a cool guy. It's a big statement, coming from the weight below, and fighting a heavyweight guy."
