Why quick KOs are not enough for heavyweight Itauma

At 21, the British heavyweight is already being heralded as the future global king of the sport's glamour division. Itauma is on a nine-fight knockout streak with every victory ending within the first two rounds. Last summer, he destroyed a fading Dillian Whyte in just 61 seconds in Saudi Arabia.

The world appears to be at his feet, but the thrill of a lightning-fast clinical finish isn't enough for Chatham fighter. He wants more. "It just went so fast," recalls Itauma, who has 11 knockouts in 13 successful contests.

"When I got to the changing room, I was a little bit underwhelmed. "In training camp for 14 weeks, for the fight to go two minutes, it's a bit underwhelming, because it's like, did I have to train all that? " Itauma faces American Jermaine Franklin at Manchester's Co-op Live Arena on Saturday.

This time, he is craving rounds. Speaking to BBC Sport, the heavyweight discusses his three-year professional career, the sacrifices of his family, and why Franklin represents his toughest test yet. Radio commentary begins from 19:20 GMT BBC Radio 5 Sports Extra and BBC Sounds before switching to BBC Radio 5 Live from 22:00.
