John McEnroe once faced some criticism for saying a low-ranked men's player would defeat Serena Williams, but the legendary tennis analyst is clearly a big fan of the women's star.
With Williams announcing her impending retirement, McEnroe is paying tribute to the tennis legend.
McEnroe believes Williams' career is similar to some of the all-time sporting greats.
"Serena’s the greatest female athlete, to me, in the history of sports. I don’t care who you could come up with. She’s one of the greatest athletes period – male or female. She’s put herself along the likes of Tom Brady, Michael Jordan, whoever you wanna say … She’s 40 years old. She’s done everything in tennis. She’s got nothing to prove," McEnroe told Fox News.
"It sounds like she wants to have more kids, awesome. She’s got a lot of other interests. People want to be a part of what she’s doing. She’ll be doing just fine. We were sort of expecting this to happen. She wanted to win a couple more, one or two more, break the all-time record, win a couple after having her daughter. That doesn’t look like it’s gonna happen but that, to me, doesn’t take away that she’s the greatest of all time."
That's extremely high praise.
McEnroe will be on the call for Williams' final matches at the U.S. Open later this month.
