James DeGale has vowed to become the first British boxer to win Olympic gold and a pro world title when he fights Andre Dirrell for the vacant IBF super-middleweight title on Saturday.
Londoner DeGale, 29, fights 31-year-old American Dirrell – whose only defeat was by Carl Froch in 2009 – in Boston.
“I’m obsessed with making history,” said DeGale, who became Olympic champion in Beijing in 2008.
“He’s tricky, talented and confident but I’m doing it for my country.”
Six British men have struck Olympic boxing gold since World War Two but none of them have gone on to win a world title in the paid ranks.
