Danny Williams has called Audley Harrison a quitter ahead of their showdown in London on 10 December. Williams claims Harrison attempted to bail out when the heavyweight rivals sparred five years ago and expects him to do the same next month.
"The Audley I see now is no different to the one I sparred with years ago," said the 32-year-old.
"I can see the old Audley having flashbacks from our session and wanting to quit when the pressure is on."
Harrison, 34, was still an amateur when he last met Williams in a ring and has since won Olympic gold as well as his first 19 professional fights.

But former British and Commonwealth champion Williams is convinced Harrison still has the mental scars.
"He will claim he was an amateur back then and that it was five years ago but in his head he remembers what he went through," added Williams.
"In the meantime he has disrespected me by saying that he could win the British title in five fights after he won the gold medal whilst I was still the champion, and by calling me a cockroach.
"Audley might look the part at the moment with his unbeaten record but he hasn't fought anyone as dangerous as me in his career and it's taken him five years and 19 fights to come back and finally face me.
"He reckons I'm damaged goods because of my fight against Vitali Klitschko but he couldn't be more wrong and I will prove it on the night."
