Bermudian brawler Teresa Perozzi is pulling no punches ahead of her seven-belt showdown with undefeated Natasha Ragosina, admitting: "I've got to knock her out to win."

Perozzi, who goes to war in Ragosina's 'own back yard' in Germany on March 15, is starkly aware she must remove the decision from the judges' to avoid falling foul of another home decision.

"I clearly won my last fight in Sweden and yet I still didn't get the result," said Perozzi who cracked Swede Asa Sandell's cheekbone and left her in a bloody mess. "I know I'll probably need to knock out Ragosina for victory. I'm confident I have the punching power, but it's whether I can effectively land them."

"When I watch tapes of previous fights it's very clear sometimes I miss opportunities or I am arm punching. Hopefully that's been corrected."

German-based Russian Ragosina is regarded as the top women's boxer in the world and the number of titles at stake is an indication how confident she is of defeating underdog Perozzi.

But Perozzi is being driven by the endless career opportunities that beckon should she upset the odds and put a dent in Ragosina's perfect record and glowing reputation.

"This fight is more intense than any other I've experienced," said Perozzi, who is competing in today's Dancing with the Stars competition. "There's so much at stake with seven belts on the line. I'm fighting someone who's undefeated in her home town and while I'm used to being the underdog this is a bit different.

"This fight could open up so many doors for me as she's ranked number one in the world. Obviously Laila Ali is not fighting at the moment but everyone is saying if Laila comes back then she should fight Ragosina.

"It's not my intention to try and get a fight with Laila, who I consider a friend. But if they're matching Laila with this girl then she must be pretty good.

"I've been watching Ragosina's tapes and she's has a very similar ring style to Muhammad Ali. Obviously my tactic is to adopt Joe Frazier's style! I'm an aggressive, come forward, type of fighter and that's what you need to be against a taller opponent like her."

The bout forms part of a three-fight package for Perozzi who, should she prevail, would fight again in Germany before locking horns with Ragosina for a re-match.

Experienced trainer Charles Romano has spent the last two weeks refining Perozzi's technique and working on tactics as she steps up her preparations for the 'winner takes all' bout in Magdeburg, Saxony-Anhalt.

She heads to New Jersey tomorrow where she will apply the finishing touches to her training programme, ahead of her quest to claim the WIBF, GBU, WBA, WBC, WIBA, IWBF and WIBC titles.

Perozzi, who works as a masseuse, suffered a sucker punch earlier this week when it emerged Government funding she was hoping for would not be made available.

But she did receive a major shot in the arm when Dunkley's Dairy and the MEF restaurant chain stepped in with sponsorship.
