Becks was watching on from home as his fellow Englishman equalled Stephen Hendry's record tally of seven world titles at the Crucible on Monday (May 2), the same day he turned 47. Sharing his delight on his Instagram story, the Manchester United and England legend wrote: "7 time world champion at 46 years old on my 47th birthday G.O.A.T Rocket Ronnie."
O'Sullivan re-posted the upload to his own story and replied: "Thanks mate." The pair haven't crossed paths in the public eye but both know what it's like to be on the top of their respective sports.
O'Sullivan can now claim to be the most decorated snooker star of all time with 21 wins at the game’s Triple Crown events to Hendry’s 18.
Who is the better sportsperson out of Beckham and O'Sullivan? Let us know in the comments section.
The Rocket could yet draw further ahead in that respect. In a separate Instagram post he teased he would return next year to try and make it a record-breaking eight Crucible crowns.
He wrote: "What a night! 17 days of graft and finally no.7 is in the bag. It’s not about records for me but winning it with my family there and against such an incredible player as Judd Trump means the world to me.
"The snooker gods were on my side this time. Thanks so much for all your support.
"I love my time in Sheffield! Back for no.8….." O'Sullivan rounded off his post with a thinking face emoji to leave question marks around his future plans.
