Nicola Adams and Marlen Esparza are in competition to win first world title

Double Olympic champion Nicola Adams says she is racing with her partner Marlen Esparza to be a world champion.

Adams, 34, stopped Mexico’s Maryan Salazar in her second professional fight in Leeds on Saturday.

American Esparza won her second bout as a professional a week earlier, becoming the first woman to box three-minute rounds, rather than the standard two.

“We have room on the mantlepiece for a world title,” said Adams. “I’ll not hear the end of it if I’m not first.”
