Claressa Shields is pound-for-pound No 1 in world over Katie Taylor in woman's boxing, says promoter

Claressa Shields deserves to be recognised as the No 1 fighter in woman's boxing ahead of Katie Taylor, believes promoter Dmitriy Salita. 

Shields just successfully defended her undisputed heavyweight championship in a dominant unanimous decision victory over Franchon Crews-Dezurn to extend her perfect professional record to 18-0.

The double Olympic champion has amassed 18 world championships across five weight classes and is the only female boxer ever to have held four major world titles in three different weight divisions.

Undisputed super lightweight Taylor similarly reigns as an icon and trailblazer of women's boxing, within which she is widely considered to be the greatest.
