Federer is so happy that Nadal is out

You can see from his face, clearly, he is so happy that Nadal is out. Even when not playing a match, he looks so relaxed. But when Nadal is around, he looked stressed.

Haha, it is really amazing that one guy has been dominated by another by so much, especially at Grand Slams! He has not beaten Nadal in a GS since 2007, that is more than 7 years! His last 4 GS win came when Nadal is either out or upset early.

Just an observation, nothing more ...
