Serena is the only female player who could intimidate me in a match, I think (of course every top 500 WTA player would throw a double bagel on me but that's not the point). If a Sharapova or an Azarenka shouted a "come on" in my face and threw a fist pump I'd be like "LOL you don't scare me b////"
Just shows you how pointless H2H's are. Nadal beat Fed but in the end it meant jack, they both walked away with nothing. It's about winning titles.
