WBC/IBO super featherweight champion Alycia Baumgardner is oozing in confidence for this Saturday's unification showdown with division rival, WBO/IBF champion Mikaela Mayer.
The fight takes place at the O2 Arena in London, as the co-feature to the middleweight unification between Claressa Shields and Savannah Marshall.
Baumgardner had her biggest win in the UK, which came last November when she blasted out Terri Harper in four rounds.
She retained her belts back in April, with a dominant decision over Edith Soledad Matthysse.
Baumgardner is not impressed with Mayer or her boxing style.
"The only thing Mikaela brings is what she always brings, which is an amateur style fighter," Baumgardner told Sky Sports. "She's a one-dimensional fighter, she looks the same as she did in the amateurs as she does in the pros.
"There are levels to this game and I believe she's only maybe up a notch in her career, I don't see anything that stands out to me. I'm not looking up Mikaela Mayer's fights, she's not that impressive to me. Credit to her for what she's done but she's not at my level, I just believe she's a one-dimensional fighter. She's basic, as they say."
The two fighters have been trading words for some time, before a deal was finally reached to make a fight between them.
Mayer has been highly critical with Baumgardner for her 2018 loss to Christina Linardatou.
"As for her comments, Mikaela has to speak herself up at this point," said Baumgardner. "She knows I'm a threat, she knows she's in there with somebody she's never been in there with before so her approach to the fight is to build the fight and make herself feel better and I get it.
"But it's comical for me at this point, it's funny to see the things she's saying and she actually believes them so it is what it is. I've already been motivated with the fact I am fighting her and with her comments it just makes the fight even more exciting because it just shows that there is so much more for people to see."
