FedEx may get his #1 ranking back but Nadal on clay is a barrier he's unlikely to cross. I'm saying that because despite all that public misconception, he's a great clay-courter in his own right. Sadly, he keeps on running into Nadal.
"O people, we created you from the same male and female, and rendered you distinct peoples and tribes, that you may recognize one another. The best among you in the sight of GOD is the most righteous. GOD is Omniscient, Cognizant." (49:13)
