O'Sullivan, 46, made history at the Crucible Theatre as he matched the record mark set by Stephen Hendry, landing himself a 21st Triple Crown title in the process. The world No 1 saved his best until last, beating Judd Trump 18-13 in an absorbing final.
But not because he wanted to apparently. Throughout the tournament, 'The Rocket' was being filmed for a fly on the wall Netflix documentary on his life, which is being made by David Beckham's Studio 99 company.
And he claims the presence of the cameras drove him to perform at his best in Sheffield, having initially struggled for motivation: "I decided a long time ago if something got too much pressure, or I thought you know what, I'm not really enjoying this, it's probably better that I lose," he told the CTGN Sports Scene YouTube channel.
"And I felt that during this World Championships. I didn't really enjoy it, but I had this film crew following me, so I thought I better try hard." And the legendary entertainer admitted he would have felt guilty had he lost.
"That's why I won it, not because I wanted to win it," he continued. "But I felt bad for the TV crew. That kind of motivated me to try harder than I normally would."
Does Ronnie O'Sullivan deserve to win BBC SPOTY this year? Let us know in the comments section.
O'Sullivan has frequently hinted at retirement throughout his storybook career, but that now appears a distant notion as he guns to break Hendry's record outright next year. He is also among the favourites to be named BBC Sports Personality of the Year for 2022.
However, the self-confessed UFC fan has also teased that he could be up for some MMA action when he does hang up his cue. After his world title success, he stated his intention to get down to business with Paddy Pimblett, having visited the Liverpudlian's gym in the past.
"I went to Paddy’s gym to watch his drills and I was open at the time to getting into a cage to do a bit of sparring," he said. "At some stage I will go to the gym in Liverpool and get grappling.”
