BBC Sport - Floyd Mayweather: All young fighters want to be like me

'All boxers want to be like me'

Floyd Mayweather says he will retire from boxing after beating Andre Berto in his 49th straight win.

Mayweather defended his WBC and WBA welterweight titles in Las Vegas as he seemingly marked the end of a glittering career.

He claimed a unanimous points victory, 120-108, 118-110 and 117-111 on the judges' score cards, against his fellow American Andre Berto.

The 38-year-old Mayweather has equalled Rocky Marciano's career record of 49-0.
