South Korean badminton duo Lee Yong-dae and Jung Jae-sung played another impressive match to beat world champions Cai Yun and Fu Haifeng of China for the French Open title.

The Korean pair, who won the men’s doubles title in Denmark last week, showed no signs of fatigue as they crushed the Chinese Sunday night.

Lee, who won the mixed doubles gold in Beijing 2008, and his partner Jung beat world No. 3 pair Mathias Boe and Carsten Mogensen of Denmark in the semifinals to play their Chinese rivals in the final for the second consecutive week.

Lee and Jung also played against them in the Chinese Masters final in September, when the Korean pair beat the home champions 21-17, 21-10.

Playing against the Chinese pair for the third time in a month, the Korean champions delivered another brilliant performance.

The Koreans started the match slowly and made successive mistakes, allowing the Chinese pair to win the first set 21-14.

But from the second set they were sharp and agile, giving their Chinese rivals little chance to score.

And the Koreans crushed the world No. 1 pair 21-15, 21-11 to win the match, raising expectations for the 2012 Olympic Games in London.
