Serena and Sharapova are totally unimpressive clay court players. Serena won her French Open before Justine began to come into her own and back when Serena was a much better player then she is today. A diminished Serena is still actually really strong on faster surfaces, but on clay her game is now far below what a potential French Open Champion should be. Once Justine came into her own in 2003, Serena hasnt won anything big on clay since it is her worst surface by far with her wildly inconsistent strokes and bad footwork. Sharapova is even worse on clay then Serena, and someone like her winning the French with her movement and overall game on clay due to Justine's terrible slump would even further expose and embarass the womens game for what it really is these days (not that how bad the current womens field now is, is that much of a secret already anyway). Justine's current horrendous form is the only reason there is any talk of either of those two winning the French, and yes Justine at about 50% is still better then either on clay, especialy Sharapova. It is really sad then when Justine goes down like she has for now there arent better people on each surface to fill in so you dont have talk of such mediocre clay courters now having a chance to win the French.
