Not only was it a masterclass, but it brought with it a sense of intimidation. Novak tends to come out one of two ways, he's either extra sharp from the onset, or unusually nervous. If Federer gets a quick start and begins to smothers Novak, there's a possibility that Novak will fold. His win/loss ration is not the best and Federer has thrown the gauntlet down.
May the best man win.
