As we all know both Fed and Nadal are on a hot winning streak on their respective favorite surfaces - Grass and Clay. Now, who do you think will lose first ie: Fed on grass or Nadal on clay? Even though I am a huge Federer fan, I have a feeling that it would be the great federer himself. He always struggle in Halle and I think after the otugh clay season he misght struggle in the first couple of rounds at Halle and might even lose a match. With this I am admitting its most likely that Nadal might retain his FO title (even tough i would love for Roger to witn the FO). Somehow Federer seems more vulnerable than Nadal these days and I cant see anybody beating Nadal on clay at the moment. So what are your thoughts
