Yes, that beautiful backhand may have been developed on another planet. Federer's at the peak of his game and he's won enough majors to have a claim on being the greatest player ever. (Although some of the other greats like Borg often never bothered to play in the Austrlian Open so would have won a lot more.)
But he'll want to keep going until he can win the French Open. If he hadn't lost to Nadal in the French final, he would have become the first player since Laver to do the grand slam. (Not including Steffi Graf who did it a couple of times, I think.)

Just another reason to rag on the french.
