KSI was absolutely obliterated by a crunching challenge from Speed just seconds into Saturday's Sidemen charity match at The Valley.
Sidemen FC took on the YouTube Allstars at the home of Charlton, with much of the pre-match build-up focusing on the participating of YouTube star Speed.
The American streamer, who went viral last year for his own twist on Cristiano Ronaldo's iconic 'Siu' celebration, certainly did not disappoint fans.

Just seconds into the match, he took out KSI with a huge challenge which could have got him a red card, had it not been in a charity match.
Rather than apologising to KSI, Speed got back to his feet and proceeded to celebrate in the British YouTuber's face in typically energetic fashion.
Talk about putting a marker down for the rest of the match.
Saturday's match saw British collective The Sidemen – made up of KSI, Ethan, Vik, Simon, Josh and Tobi – take on a YouTube all-stars side to raise money for four different charities.
ChrisMD, Chunkz, MrBeast, Noah Beck, Cal the Dragon, Niko, Deji, Filly, LazarBeam, Jidion, Logan, Harry Pinero, Randolph, Castro, Karl Jacobs, Manny, Calfreezy and Chandler Hallow were also expected to feature in the match in south London.
There were also rumours that KSI's former opponent in the boxing ring Logan Paul would take part in the match.
But the American, the older brother of YouTuber-turned-boxer Jake Paul, was not named on the team-sheets for the charity game.
Earlier this week, the Sidemen announced that Billy Wingrove and Mark Golbridge would be managing the respective sides at The Valley.
It is the first time the event has taken place in four years, with the last one in 2018 ending in a comprehensive 7-1 victory for Sidemen FC.
On this occasion the Sidemen emerged victorious with a thrilling 8-7 win as hundreds of thousands of pounds was raised for charities like CALM and the Teenager Cancer Trust.
