RG was the main goal for Nole in 2012 as well
If Nadal plays well, not even great, nobody can touch him there.
Yes but he was concerned by the Olympics and he had to defend his great 2011 season, he felt rather happy to progress and to make the final in the French, but he won't be satisfied next year in such a scenario, for sure
He won't have the same pressure everywhere, but i have the feeling that the medias will be focalized in this tournament, he will probably be asked this question a billion time like Federer in the past "Do you feel you can win Roland Garros this year" The pressure can only grow up.
Notice that the French was probably his poorest slam in term of level of play this year, if he play like 2011 (tough ask but not impossible), Nadal will have to be at his best to beat him, better than he was in 2011 and at least as good as he was this year.
In this moment, and counting on a Nadal resurgence, i see it like this
Nadal 80% Djokovic 15% Federer 2% (Djokovic winning against Nadal in a 6 hours marathon and folding in the final) Murray 1% (same as Federer) Del Po 1% (in fire) Rest (1%)
