Jake Paul explains how he became world's best-paid boxer with $45m earnings

YouTube star Jake Paul believes his innovation helped him become the world's highest-paid boxer last year.

Paul won three professional fights last year by knocking out Ben Askren and beating ex-UFC champion Tyron Woodley twice. The 25-year-old has made his stamp on the boxing world by earning a massive $45million for those three fights.

'The Problem Child' has taken some time away from the ring to focus on promoting Katie Taylor vs Amanda Serrano later this month, but is targeting a return in August.
