Well there can be no doubt that Federer on grass is like Sampras in his heyday. Doesn't always have his way on hard courts with Nadal about and he could have had an easier draw. Likely to face Henman (Come on Tim
) in the second round and then Ancic at the QF stage. Couldn't put you off him at all though.
If you're looking for someone with a good draw Ljubicic could be your man, though whether he really likes the surface is open to debate.
