Many were quick to call the NFL legend the "G.O.A.T." or "Greatest Of All Time" after the win, but others were quick to point out that Williams has 23 Grand Slam singles titles.

Ohanian, who is always outspoken when it comes to praising his wife, made his stance clear on the greatest athlete debate with his T-shirt.
Williams also shared a post after her win on Tuesday, in which she wrote, "The smile says it all. This proud mama marches on."
In a post-game interview, she described her win as "the best match" she played during the tournament.
