Shields or Taylor the greatest? "We're 1A and 1B!"

Claressa Shields has hailed the greatness of Katie Taylor and says she holds no qualms over a fight between the boxing greats never materialising. 

Taylor enters her farewell bout this weekend when she takes on Flora Pili in an undisputed super-lightweight world title clash at Dublin's Croke Park in front of more than 80,000 fans.
