Fury beat Chisora on points in 2011 and the rematch, which is sold out, represents a WBO world title final eliminator to set up a bout with IBF, WBA and WBO champion Wladimir Klitschko.
The build-up to the fight has been mired in controversy.
Fury was fined £15,000 by the British Boxing Board of Control for a foul-mouthed rant in September and, at his next media outing, put tape over his mouth and refused to answer questions in protest.
Fury was a picture of calm at the final press conference yesterday and the 6ft 9in fighter admits his attention is now fully focused on matters in the ring.
“We’ve had five or six press conferences now — I’ve done talking, I’ve done no talking, I’ve done everything really,” Fury said.
“The fights are 50/50 fights – they’re real fights, it’s a 50/50 event.
“Anyone can be victorious on the night from all the fights.
“Is our fight a 50/50 fight? He’s got a pair of gloves on and two arms so I suppose it is 50/50.”
Fury’s analysis represents a dramatic climbdown from previous predictions claiming he will knock Chisora out and that there was no chance the battle would go the distance.
The 26-year-old has fought only once in the last 19 months, registering a comfortable victory over Joey Abell in Febrary, but insists he is in excellent shape.
“This is the hardest I’ve ever worked to get off all that weight, absolutely,” Fury said.
“We’ve been doing all sorts of extravagant things. Peter (his brother and trainer) has been having me carry him up the stairs every morning and every night as a training exercise.
“He’s had me run around the park with him on my back so it’s been a harsh training camp.”
Chisora, who has lost to David Haye and Vitali Klitschko since his defeat to Fury three years ago, pulled out of the initial rematch in July due to a fractured hand. The 30-year-old claims he cannot wait for Saturday’s showdown.
“We’re excited, myself and the big man are ready to rock and roll. For me, I know when we glove up it’s fight time. If you leave there disappointed by the fights, I don’t know what you’re doing there. I’m ready to fight.”
