Friday night at the 2022 Laver Cup in London, Federer and Nadal played in a doubles match, losing to Frances Tiafoe and Jack Sock in the final match of Federer’s storied career.

One picture in particular, in which Nadal and Federer briefly hold hands as the tears flowed, made its rounds. 

"Well, I mean, it was a short moment," Federer told The New York Times. "I think at one point, I was sobbing so hard, and I don’t know, everything was going through my mind about how happy I am to actually experience this moment right there with everybody. And I think that’s what was so beautiful about just sitting there, taking it all in while the music was playing, and the focus was maybe more on her [the singer Ellie Goulding]. So, you almost forgot that you’re still being taken pictures of.

"But it very quickly got clear on the phone, and Rafa told me, ‘I will try everything I possibly can to be there with you,’" Federer told the paper. "And that felt obviously incredible for me. And it showed again how much we mean to one another and how much respect we have."

"I just thought it ended up even better than I ever thought it would," Federer continued. "So, an incredible effort by Rafa, and I’ll obviously never forget what he did for me in London."
