Despite Nadal winning both the French Open and Wimbledon, Federer remains World Number 1. I think that Nadal has proven he is the best player this year but you can't just forget Federer's past achievements. I think for the time being it is fair on Federer to still be ranked as the best player in the world, but if Nadal wins the U. S Open, Nadal should be rightfully recognised as the best player.

What do other people think?
