Serena Williams’ former coach has made a bold claim about the US Open, hinting at a potential return to action for his old student.

And, if it were to occur, what better event than the one she won six times in singles, and a further two times in the ladies’ doubles too.

At this point, this is all hypothetical. There has been no suggestion that Serena Williams will be coming out of retirement to play with her sister, who has made a return to the WTA Tour in recent months.

Whilst Venus Williams’ desire to keep playing burns on, it remains to be seen whether her sister feels the same.

However, Rick Macci has now stated what he’s almost certain would happen if the two did unite for one last dance in New York.

Taking to X, he has hinted at Serena’s potential re-emergence from retirement a few times before, but seemingly with no inside knowledge.

He is merely speaking as a fan of one of the greatest players in the history of the sport, praying that the unthinkable could possibly occur.

Will Serena will play dubs with Vee at the OPEN. If she does even the practice court would have 10 thousand eyeballs popping non stopping watching two sisters who moved like twisters even with blisters and would be would must see TV to watch a Goat and Vee. @serenawilliams

After all, Serena has been pictured hitting since her departure from the sport in 2022, as recently as July.

This naturally sent fans into a frenzy, with Macci just another tennis supporter who would obviously love to see this superstar return.

And now, he has made a claim about what he’s certain would happen at the US Open if they did play together come the end of this month.

What did Venus Williams say about Serena Williams coming out of retirement?

With Venus Williams having been granted wildcards into Washington and Cincinnati, she is well and truly back for the North American swing of the tour.

And, given her legendary status, she would likely be granted entry into any event she wanted.

Speaking during her official comeback event, after over a year out of the game, somehow the topic of Serena cropped up.

Interestingly, she did not rule out the possibility of a comeback, telling the press: “I keep saying to my team: The only thing that would make this better is if she was here.”

She then joked: “Like, we always did everything together, so of course I miss her. But if she comes back, I’m sure she’ll let y’all know.”

Venus finished by reiterating just how good Serena remains even to this day, concluding by stating: “She can take six months off and she clocks it clean. You can’t teach that kind of talent. She’s just so good.”

Perhaps Macci knows something we don’t.
