wimbledon surface: who is some-more dominent upon their particular surface?
Federer in grass? or Nadal in Clay
I feel Nadal is some-more higher in clay as well as roughly he is resolute yet Federer is not so dominent in weed as Nadal is in clay .Federer struggles opposite Nadal in final year Wimbledon as well as Nadal roughly threatens to win it as well as longed for by a hair
