When she's at the top of her game, there's no current female tennis player who can touch Serena Williams. So, given her ability to run circles around her competition, it begs the question: could she give good comp or even beat a professional male tennis player, like Andy Murray. Well, on Thursday, Serena appeared on Late Show With David Letterman and that exact topic came up in their conversation.

As you may recall, Murray was approached by someone on Twitter about the possibility of facing Williams in the near future and he said he'd definitely be up for it. So, what's the hold up? Apparently, it's Serena, who actually feels as though she doesn't have a chance in hell against the No. 3-ranked player in the world.

Check out the video to see Serena's surprisingly honest prediction for a hypothetical match against Murray.
