Amir Khan has said that he "hates" Lamont Peterson and 'wants to hurt him' when they square up in Las Vegas on May 19.
The Bolton fighter once again insisted that he won their first fight in Washington in December and has promised to give the American a "boxing lesson".
"We respect each other from a certain point of view, but I don't like him because he has my titles - I am going in there to hurt him," the 25-year-old told The Sun. "In fact, I hate him as he has something I want - the belts that he took off me.
"I've never felt like that before. I want to hurt him and knock him out. But I don't hold a grudge because when you do you can make mistakes. This rematch is all about winning. I am not going in the ring at the Mandalay Bay to be crazy and wild.
"I want to show him by handing out a boxing lesson. This is definitely a make or break fight for me as there is so much to lose if I don't get back my titles. I honestly thought I won our first fight. This is unfinished business."
The fight will be Khan's fifth in America in his last six bouts.
