Roger Federer is an amazing tennis player and athlete. In US Open semi-finals game versus Novak Djokovic, Federer had an amazing behind and between the legs shot. If it wasn't secure before, now it is, Roger Federer is the greatest tennis player of all time.
I also love Djokovic's face after the shot--pure disbelief and admiration. The two had fun playing, making it entertaining to watch. It was an unbelievable match to watch.
