John McEnroe, known for his hot temper, and impressive tennis skills, f*cked up.

In a NPR interview Sunday as part of a tour promoting his “But Seriously,” memoir, the former star athlete had some choice words for Serena Williams and how she’d perform on the men’s circuit.

So what did he say? Apparently he believes that if Williams played in the men’s circuit she’d be “like No. 700 in the world.”

Really, John?

“That doesn’t mean I don’t think Serena is an incredible player. I do, but the reality of what would happen on a given day is Serena could beat some players, I believe, because she is so incredibly strong mentally…But if she had to just play the circuit — the men’s circuit — that would be an entirely different story,” McEnroe said.

The 58-year-old went on to say that maybe at some point a women’s tennis player can be better than anyone else.

“I just haven’t seen it in any other sport, and I haven’t seen it in tennis. I suppose anything’s possible at some stage.”

McEnroe has given the 39-time Grand Slam winner props in the past, saying, she was “arguably the greatest athlete of the last 100 years,’ after he witnessed her 2015 Wimbledon win.

John McEnroe, you can’t be serious.
