BBC Sport looks at the numbers behind Daniel Dubois' first meeting with Oleksandr Usyk and what he has been doing to prepare for the rematch on Saturday.

Regardless of what happens in his rematch with IBF heavyweight champion Daniel Dubois on Saturday, WBA, WBC and WBO champion Oleksandr Usyk already has a Hall of Fame resume. Beating Dubois would make Usyk -- a former undisputed cruiserweight champion -- undisputed heavyweight champion for the second time in his career.

Usyk moved backwards a little more in the second, and he began to signal to the referee that Dubois’s punches were straying low. Dubois threw an uppercut near the end of the round that landed, but he was stiff and moved in straight lines towards Usyk.

Oleksandr Usyk and Daniel Dubois contest a high-stakes rematch at Wembley this weekend with the undisputed heavyweight championship of the world on the line.It is just under two years now since the duo first met in Poland,
