Heavyweight contender Derek Chisora has backed YouTuber star KSI to beat Tommy Fury in a boxing match.

KSI - real name Olajide Olayinka Williams 'JJ' Olatunji - returned to the ring on Saturday at London's O2 Arena in London, and won two fights on the same night. The first came against a rapper named Swarmz, and second bout was against an unknown in Luis Alcaraz Pineda - a novice professional boxer who entered the ring with a record of 2-5 with four of those defeats by knockout.

Fury (8-0, 4 KOs) and KSI exchanged words in the aftermath of the event.

Chisora believes the social media personality would win that fight.

"I’d like to see that, one hundred percent, let’s make that happen," said Chisora to Boxing Social.

"What’s Tommy Fury done in the last two years? Nothing. KSI. Smoke him. You know, Tommy Fury will not fight KSI because he knows if he loses to KSI the traveler community will never ever respect him and KSI will knock him out."

Fury last fought back in April, when he picked up a stay-busy win on the undercard to older brother Tyson Fury's knockout win over Dillian Whyte at Wembley Stadium.

He was scheduled to fight another social media star turned boxing, Jake Paul, but the fight fell apart when Fury found himself unable to enter the United States.

KSI nearly approached Fury to face him last Saturday, before going in another direction.

"We didn't approach him but we were thinking about it before we went down the two fight route," KSI said.  "We were thinking about putting the feelers out there but we understood he wasn't in the right physical shape to come in on shorter notice which is fair enough. But yeah why not in the future?"
