IBF, WBA, WBC middleweight champion Claressa Shields has no problem with playing the part of the villain in her upcoming fight with WBO champion Savannah Marshall.

The two will collide in a long-awaited undisputed title fight on September 10th at the O2 Arena in London.

Shields, a two-time Olympic gold medal winner, lost a decision to Marshall in the amateurs. To date, that outcome remains the only blemish suffered by Shields, as an amateur or pro, in a boxing ring.

Before an expected hostile crowd, Shields is very motivated to make a statement in the fight.

"Whoever supports Savannah Marshall, I want them to hate me after this fight. I'm fighting against all them," Shields, 28, told BBC Sport.

"I live for these moments and I live for this platform. They will remember me after this. The girl came over from Flint, Michigan with the blue hair. I'm coming to make the whole country mad."

Shields believes the moment is just right for what's being billed as one of the biggest fights in the history of women's boxing.

"When I turned professional, close people to me told me my aspirations were too big. Fighting at the T Mobile arena, making a million dollars, fighting on TV, was too big," Shields says. "Everything I said about myself and the future of women's boxing, I was right," Shields said.

"Savannah isn't ready for this media attention. She's been saying my name over and over again. First she said she will knock me out. Now she's going to outbox me. Which one is it?

"She's getting smarter and realizing this fight won't be as easy as she thought. Now she's in with an elite fighter. I plan on hurting her and I plan on surprising her."
