WBC, WBA junior middleweight champion Claressa Shields is getting irritated by the statements coming from amateur rival Savannah Marshall.

Shields is back on March 5th, when she faces undefeated IBF champion Marie-Eve Dicaire in a unification. The WBO title will also be at stake, making the contest a full division unification.

Shields has captured titles at super middleweight and in April of 2019 became the undisputed champion at middleweight when she unified the WBO, WBA, IBF, WBC titles with a domination of Christina Hammer.

Back in October, Marshall captured the vacant WBO middleweight title with a stoppage win over Hannah Rankin.

Marshall, 29-years-old, beat Shields in an amateur bout in 2012 - and she's been far from quiet when discussing that victory to fire up a rivalry in the pros.

Shields had a very successful amateur run, winning two Olympic gold medals before deciding to turn pro.

She's very confident in her ability to beat Marshall in the pros.

"I have to rate Marshall as a six out of 10, six being a little above average. I won the Olympics twice, she was there. I won the World Championships as an amateur twice, she was there. She wasn't on the podium," Shields told BBC Sport.

"She is using my name to help sell her fights. No-one cares about her fighting. People say 'who is the girl who beat Shields?' Then she barks and barks and barks, people give her attention. I'll go over to England and smoke her or she can come over to the US and I'll smoke her here. It's not really going to be hard and she knows that.

"Claressa Shields ain't ducking no smoke. And she should be ashamed of herself. She's just won her first belt. Now she's trying to tell her world that I'm afraid of her. Baby girl, you have a lot of catching up to do. You should be very ashamed."
