The two big-hitters go at it on Frank Warren's Wembley Arena card on Saturday, but went face-to-face for the first time at Chisora's North London gym on Tuesday.
American Scott failed to attend a press conference on Monday saying he was not informed of it by the promoters.
But Chisora is having none of his opponent's explanation for missing the presser, and says he has now seen the fear in his body language.
"I'm happy now that I've looked into his eyes and I see that the boy is scared," said Chisora.
"I don't believe all this rubbish he's saying that he didn't know about press conference yesterday, he just didn't want to see me,"
"He even had to be forced to take off his sunglasses as we went face-to-face,"
"What counts is what happens in the ring on Saturday and I'm going to do a real good job on this boy and pack him back off to America, defeated."
Chisora's trainer Don Charles added that his man is in the best shape of his career.
"Scott looks in great shape which is good news for us as it will be all the better when Del beats him," said Don.
"Trust me, Del is in the best shape of his career and Scott will be not be able to stand the heat that Del is going to dish out,"
"Scott has not met anyone like Del and he's caught him at the wrong time, Del is hungry and cash and title loans determined as he knows he can't afford to lose this fight."
