Jake Paul vs Anthony Joshua: Spectacle & serious risk looms large over Miami fight

When Anthony Joshua made his professional debut against Emmanuel Leo in 2013, fresh from Olympic gold in London, the boxing world treated it like the start of a coronation.

At roughly the same time, a 16-year-old prankster from Ohio named Jake Paul was posting six-second Vine videos - chatting to pineapples in supermarkets and climbing into strangers' shopping trolleys for a laugh.

More than a decade later, through wildly different routes, the pair have arrived at the same place.

This Friday, in Miami, they will share a ring in a professional heavyweight contest that still feels faintly unreal.
