Roger Federer and Rafael Nadal were one match away from their first clash of the season on Friday after clinical wins in the Monte Carlo quarter-finals.
Swiss world number one Federer outclassed David Ferrer of Spain 6-1, 6-3 in just 61 minutes while defending champion and number two Nadal defeated Argentine Guillermo Coria 6-2, 6-1 on Centre Court.
"I fought well today. I'm satisfied with my performance," said the 19-year-old Spaniard, who missed the Australian Open won by Federer through a left foot injury in January.
The French Open champion picked up his 40th consecutive win on clay which puts him joint third with Austrian Thomas Muster of Austria on the all-time list headed by Argentine Guillermo Vilas who won 53 in a row.
Nadal will face Gaston Gaudio in the semi-finals after the seventh-seeded Argentine, winner of the 2004 French Open, defeated Spain's Tommy Robredo 6-1, 6-3.
"Gaudio is a real clay specialist and he played a very impressive game against Robredo," Nadal said.
Coria, who won the Monte Carlo Open in 2004 and was Nadal's final opponent last season, is also a staunch clay-court basline player but his only impact on the match was to lead 2-0
Nadal won 11 games in a row to lead 6-2, 5-0 before Coria escaped an humiliating 6-0 defeat with a last-gasp effort and saved two match points in the next game. The Spaniard sealed the match on the third.
Federer clinched his quarter-final on his first match point dominating eighth seed Ferrer throughout.
"It's my first tournament on clay but I have been practising with the French Open in mind for six months and I felt well physically today," said the Swiss, who is still chasing his first win at Roland Garros.
Federer's semi-final opponent will be Ivan Ljubicic of Croatia or Fernando Gonzalez of Chili who were facing each other in the last quarter-final.
"If I had to choose, I would pick Lubijic because I defeated him everytime we met but both of them are playing well and it will be a difficult match," he said.
