Novak Djokovic sets up quarter-final with 'old man' Tommy Haas at French Open
Serbian ace stays on course for career slamas German veteran takes place in record books

World number one Novak Djokovic reached his 16th consecutive grand slam quarter-final yesterday to set-up a clash against evergreen Tommy Haas for a spot in the French Open semi-finals.
Top seed Djokovic carved out a 4-6, 6-3, 6-4, 6-4 win over 16th seed Philipp Kohlschreiber, with the German paying a high price for converting just two of 13 break points.
German 35-year-old Haas, meanwhile, became the third oldest man to reach the last-eight with a comfortable 6-1, 6-1, 6-3 win over volatile Russian Mikhail Youzhny.
"I needed to earn my victory, and in the end it was good. I'm really glad to get through, because he's a good quality opponent and he's a specialist for this surface," said Djokovic.
On facing 12th-seeded Haas, against whom he has a 4-3 winning record, the Serb said: "I have a lot of respect for Tommy. He is playing well."
Djokovic, the runner-up to seven-time champion Rafael Nadal last year, needs a French Open title to complete a career grand slam. The last time he failed to reach the last-eight of a major was in Paris in 2009 when he lost in the fourth round to yesterday's opponent.
