An historic win

Serena Williams has won a lot of tennis titles over the years, but she has never won an Olympic singles gold medal. Until now. With her dominant win over Maria Sharapova in the final match, Williams becomes the first woman in history to win all four Grand Slam titles and Olympic gold in singles and doubles. Is there any question she's the best ever?
