There was no way Djokovic was expected to lose that Roland Garros meeting. Djokovic was undefeated on clay this year, while Federer was woefully out of form. I think there was a lot more going on mentally than physically. Federer was having a poor year before Roland Garros, and he has had a poor year after Roland Garros. Nothing has gone his way except for that meeting with Djokovic. The result made no sense, except perhaps Federer has a mental edge over Djokovic, barring the Australian Open 2008/2011. Last year's US Open meeting where Federer had matchpoints was effected by the prospect of playing Nadal the next day. Federer later admitted he was thinking about Nadal during the Djokovic match. When you think about it, Federer would hate to play Nadal at the US Open if he was not physically fresh, because it really is the most important match of Federer's life. Lose to Nadal at the US Open and he will have lost to Nadal everywhere (and never beaten Nadal in the hardcourt slams). So I think Federer continues to hold the match vs Djokovic on his racquet (outside of Australia).
