John McEnroe Believes He Can Beat Serena Williams Right Now (Video)

Serena Williams suffered just her second defeat of the season Saturday, when she lost to Belinda Bencic in the Rogers Cup semifinals. Williams, 33, is in the midst of one of her most successful seasons ever, as she goes for a calendar Grand Slam at the U.S. Open.

But someone thinks he can beat Williams. Yes, that’s right — he. 

Tennis legend John McEnroe appeared on “Jimmy Kimmel Live!” Wednesday night, and promptly started an uproar when he said he could still take on Williams on the court.

Not many current tennis players can beat Williams right now, let alone a 56-year-old who retired in 1992.
