Djokovic doesn't look much better than the Tsonga at Roland Garros, so who else is there? Maybe Almagro will be Nadal's main rival at Roland Garros. Nadal beat Almagro in 2008 and 2010. The 2010 meeting was Nadal's tightest match of the tournament - 7-6 7-6 6-4. Almagro seemingly has improved since then. Nadal may have improved too however. We'll see.
