KSI challenges Jake Paul to winner-takes-all mega-fight at Wembley: 'Put your money where your mouth is!'

The two YouTuber-turned-boxers have traded insults over social media in the past few days after both of their scheduled fights this month suffered last-minute setbacks.

KSI, real name Olajide Olatunji, mocked Paul over the cancellation and offered him a spot on the undercard of his fight against Alex Wassabi, which was due to take place at the O2 Arena on August 27.

But KSI announced on Saturday that he would instead face rapper Swarmz after Wassabi was forced to pull out of the event after suffering a concussion in training.

"If he doesn't accept the fight with me we all just know that he's scared," said Paul, in a video on Twitter.

"KSI I will come to London I will weigh 180lb for the fight, you can be the A-side, what's your excuse? Do you accept?"

KSI later responded: "We will fight on my terms and when we do, it'll be done on the biggest stage. I'm talking Wembley stadium fam. With a full camp tailored just for you and I, so that there are no excuses when we fight. None of this short notice s**t."

KSI followed that up with a new challenge to Paul on Monday morning, offering the American a winner-takes-all fight at the home of English football.

"I'm gonna send you a contract. We fight next year. Wembley Stadium. Winner of the fight takes all. 100% of the purse will be on the line," he tweeted.

"Put your money where your mouth is and let's finally end this. Will you accept?"

Paul holds an unbeaten professional record of 5-0, having last beaten former UFC champion Tyron Woodley in a rematch in December.

KSI, meanwhile, has fought just once professionally, beating Paul's older brother Logan via a split decision back in 2019.
