Lamont Peterson is confident that he can beat Amir Khan for a second time in Las Vegas, next month, and thinks the English boxer is feeling the pressure in the build-up to the bout.
Khan claimed Peterson had robbed him of his WBA and IBF titles following the American's victory on a split decision, four months ago.
Khan, the favourite for the clash in the boxing betting, is set to try out a different approach in the rematch, after being penalised for pushing in the first fight, but Peterson believes he will win whatever Khan throws at him.
"I'll be relaxed like I always am in the ring, but he's putting a lot of pressure on himself, saying he won the last fight; saying he's going to change this and that for the next fight," said Peterson.
"He's still out there saying he's the champ, but he's not. He's all over the place. Really, I don't know what to make of him.
"If he fights on after he loses to me, he's going to lose to average fighters, not just world champions. People need to see what you can do, not just hear what you can do."
Peterson has won 30 of his 32 fights - 15 by knockout - with his only defeat coming against Timothy Bradley in a WBO light welterweight title fight in December 2009, when he lost on a unanimous points decision.
Khan, the youngest British Olympic boxing medallist ever, when he won silver in Athens eight years ago, has won 26 of his 28 professional fights. His only other loss came in June 2009, when Breidis Prescott beat him.
