Sounds like Federer wasn't all that classy in defeat as usual:http://www.guardian.co.uk/sport/2011/sep/11/us-open-2011-federer-djokovic
Asked about the quite remarkable forehand winner Djokovic hit to save match point, Federer reckoned the Serb did not look at that point like someone "who believes much anymore in winning. To lose against someone like that, it's very disappointing, because you feel like he was mentally out of it already. Just gets the lucky shot at the end, and off you go."
Djokovic was honest enough to admit the shot was a gamble – but Federer was reluctant to give him credit even for that courage in a crisis, preferring to regard it as desperate.
"Confidence? Are you kidding me?" he said when it was put to him the cross-court forehand off his first serve – described by John McEnroe as "one of the all-time great shots" – was either a function of luck or confidence.
"I mean, please. Some players grow up and play like that – being down 5-2 in the third, and they all just start slapping shots. I never played that way. I believe hard work's going to pay off, because early on maybe I didn't always work at my hardest. For me, this is very hard to understand. How can you play a shot like that on match point? Maybe he's been doing it for 20 years, so for him it was very normal. You've got to ask him."
