Irish superstar Katie Taylor expects Mikaela Mayer and Sandy Ryan to deliver another competitive fight and feels the fighter who makes the better adjustments will win Saturday's world title bout in Las Vegas.
Briton Ryan has an opportunity to settle the score and regain the WBO welterweight title after she was outpointed by American Mayer, 34, in New York in September.
The fight was marred by Derby's Ryan, 31, being hit with red paint before leaving for the venue.
"The last fight was touch and go could have gone either way. Mikaela probably did deserve to win the fight maybe, but it was a very close fight," Taylor told the BBC 5 Live Boxing with Steve Bunce podcast.
