Urgh, if I hear commentators exclaiming one more time how surprising it was that Nadal and Djokovic, as well as Federer and Djokovic played against each other more than Federer and Nadal...
It's simple. For a long time, Federer and Nadal were ranked 1 and 2 and could only play in finals. Novak was ranked number 3 and faced them in god knows how many semis. It's not that difficult to explain why.
Anyway, looks like it's going to be one of those frustrating days where we never know when the final will start, if at all.
