“When ever you start doubting him, he seems to upset the apple cart and this time is no different.
“I think both the styles gel well. Parker is a slick boxer, he’s got a great jab, tremendous right upper-cut and right cross and Dereck has to stay away from those two weapons.
“If he can stay away and put the pressure on Parker then I think he can grind him down.
“If you have a boxing match with Parker, he’s a master boxer so Dereck will somehow have to get past that jab and to do that we’ve brought in young Daniel Dubois who’s got a great jab and he’s trying to give himself the best chance of victory.”
Haye added: “He’s [Chisora] coming off one loss. The fact he’s got an opportunity like this against Parker off the back of a loss shows that people in the business understand that his efforts against Usyk deserved another big fight.
“This time around, he doesn’t want to leave it to the judges. He’s going for the stoppage, he’s going out there all guns blazing.”
