Paris: Two fellow Spaniards who have already beaten him on his favourite clay surface could lie in wait for favourite and defending champion Rafael Nadal at the French Open.
Friday's draw, conducted by Nadal at Roland Garros, also handed women's champion Serena Williams a tricky route.
Eight-time champion Nadal plays American Robbie Ginepri in round one but Nicolas Almagro and David Ferrer are seeded to face him in the fourth round and the quarterfinal respectively.
Almagro surprisingly beat Nadal in the quarterfinals of the Barcelona Open while Ferrer, who the Mallorcan beat in last year's French Open final, knocked him out at the same stage at the Monte Carlo Masters.
"Last week in Rome was tough physically but sometimes you need these things. I played a bit better during the tournament," Nadal told a news conference.
Defeat by Novak Djokovic in the Italian Open final meant Nadal has lost three matches on the European claycourt swing for the first time in a decade, raising doubts over his form.
Djokovic, chasing the only Grand Slam title missing from his collection, takes on Portuguese Joao Sousa in the first round en route to a possible semifinal showdown against former world No. 1 Roger Federer.
Fourth seed Federer plays Slovakian Lukas Lacko in the first round while his fellow Swiss Stanislas Wawrinka, the third seed, faces a tough first round against plays Spaniard Guillermo Garcia-Lopez in round one. Wawrinka is seeded to meet Nadal in the semifinals.
Briton Andy Murray, the seventh seed, is on collision course with Wawrinka after a last-eight spot in Rome boosted his confidence following a rough start to the year. Murray is up against Kazakhstan's Andrey Golubev.
Women's champion and world No. 1 Williams was drawn against France's Alize Lim in the first round before a likely quarterfinal clash with Russian Maria Sharapova, whom she beat in last year's final.
Seventh seed Sharapova, who won the Stuttgart and Madrid titles this year back to back. She faces a qualifier in round one.
Second seed Li Na of China also faces French opposition in round one in the shape of Kristina Mladenovic.
The top half of the women's draw looks tougher than the bottom with Wimbledon runner-up Sabine Lisicki, Australian Samantha Stosur and third seed Agnieszka Radwanska lurking.
