You can't count Fed out but you can notice the general trend he's shown when a slam match goes to 5 sets. He lost to Tsonga and Djokovic last year in 5 sets and if the French open went to 5 then Djokovic would have won it probably.
Vs Tsonga, I think it was pure luck, Federer played better the first 2 sets, but Jo is a great, great player and he had chances to beat Nole... But 2011 was Nole's year.
What you say about Roland Garros is false IMO, Djokovic couldn't close the 4th set, and Fed outplayed him in most of the match.
And about the USO, even in 5 sets, Fed deserved to win and he choked really bad, like Murray this AO. Things went to Djokovic side this time, but you must be so fuckin blind if you think Fed couldn't win 5-set matches.
