I heard this saying about ten years ago, coming out from a buddy who doesn't actually play any real sports, it did bother me a little, especially when at that time women's tennis wasn't too 'attractive'.
Until in recent years women's tennis has been dominated by mostly good-looking eastern european product. They came from the same geographical location, went through different routes in developing their game, some stays, some went to other parts of Europe and some to the US, but they manage to find each other in the top 50's world ranking. Ok enough mumbling.. below is a photo of the current World Number 1.. pretty girl isn't she?
