1. (SOUNDBITE) (English) FORMER EUROPEAN HEAVYWEIGHT CHAMPION, DERECK CHISORA, SAYING:

3. (SOUNDBITE) (English) FORMER EUROPEAN HEAVYWEIGHT CHAMPION, DERECK CHISORA, ON BIG WEIGHT DIFFERENCE BETWEEN FIGHTERS, SAYING:

"Andy cannot lose more weight or else he will become very small and he cannot take the shots. So, I think him coming in heavy is better for him so he can take AJ's power like he did last time. So, if he loses more weight and he gets hit he can't get up."

5. (SOUNDBITE) (English) FORMER CRUISERWEIGHT WORLD CHAMPION, JOHNNY NELSON, ON FIGHT TACTICS, SAYING:

"He has to be on complete form here, he has to use his smarts here. It's not just about the physical attributes it's about mental and mentally he has to stay disciplined and he has to box like a bull and a matador. He's got to use the weight to his advantage and let him slip past and drop past and hit him hard, make him know he's there."

STORY: British boxing champions Johnny Nelson and Dereck Chisora are predicting a difficult fight for their fellow countryman Anthony Joshua as he faces Mexican-American Andy Ruiz in a world heavyweight title rematch in Saudi Arabia on Saturday (December 7).

Joshua, who's fans have travelled to the Arab country in numbers, weighed in more than three stones lighter than champion Ruiz at 16 stones and 13 pounds (107.5kg), the former champion's lightest ever weight for a world title fight.

Ruiz, showed 20 stones and three pounds (128.3kg) -- heavier than the first showdown between the two at New York's Madison Square Garden in June.

Saturday's WBA, IBF and WBO heavyweight title rematch has been promoted as the 'Clash on the Dunes'.
