Joe Fournier has promised to leave YouTube star KSI "twitching on the floor" when he knocks him out in their pay-per-view fight on May 13 in London.
Fournier is 9-0 as a professional boxer, and has previously held a ranking with the WBA at light-heavyweight as well as an international title. He is viewed as a major step up in competition for the UK's biggest social media star, who has previously faced YouTubers, rappers and a journeyman fighter as a short-notice replacement.
KSI has been taking to social media to show off his intensive training, while Fournier appears to still be enjoying his life in Miami, taking in the nightlife after training during the day. However, that hasn't deflated the Londoner's confidence, and he believes that it will be a dominant win in their Wembley meeting.
