PARIS: Novak Djokovic, the youngest player left in the French Open, and veteran former champion Carlos Moya, the oldest man standing, moved into the Roland Garros quarter-finals on Monday.

Sixth seeded Djokovic continued Serbia's French Open surge when he defeated unseeded Spaniard Fernando Verdasco 6-3, 6-3, 7-6 (7/1) to reach his second successive quarter-final.

Thirty-year-old Moya, the 23rd seeded Spaniard and the winner here in 1998, set up a potential last eight clash with defending champion Rafael Nadal by defeating 35-year-old Jonas Bjorkman of Sweden 7-6 (7/3), 6-2, 6-4.

Nadal, who has never lost a match at Roland Garros, takes on Australia's Lleyton Hewitt in a mouth-watering fourth round match-up later Monday.

Djokovic awaits the winner of the tie between Cypriot 16th seed Marcos Baghdatis and Russia's Igor Andreev.

Djokovic will be the third Serb to feature in the last eight with compatriots Jelena Jankovic and Ana Ivanovic already in the quarter-finals of the women's singles.

After struggling to impress in his first matches, Djokovic, who needed over four hours to see off French wildcard Olivier Patience in the third round, clicked into top gear against Verdasco.

"I'm really happy with the way I played because I didn't play very well at all in the first three rounds," said Djokovic.
