Men's:
Murray > Ferrer > Tsonga > Djokovic > Federer > Youzhny > Mayer (sorry but I don't think Youzhny or Mayer are really GS Champion material >.>)
Top three have got to be three of the best ever male tennis players never to have won a slam.
Women's:
Radwanska > Kerber > S. Williams > Azarenka
Always been a fan of Radwanska... but i really doubt she can beat the winner of the other SF.
