There are so many players in the top ten who have the game to be winning slams, all talented although differently. At the end of the day it is who want it more, take for instance justine vs Kim, Venus vs Serena , Lindsay and Amelie vs the above four. Justine and Serena have won their slams more from intensity and determnation, I mean both Kim and Venus match up well against them respectively.
Rena- a tennis great! 22 at striking distance.
