The clash between world number one Lee Chong Wei and world number 3 Lin Dan will be the most anticipated of the badminton thus far. This clash deserves gold medal billing, as it has been at the past two Olympics.
The two great rivals have come up against each other a number of times with the Chinese player holding a 25-11 advantage in overall meetings. Dan has also beaten Chong Wei in the last two gold medal matches and the Malaysian will be keen to get one back on his opponent and make it to the summit clash for the third successive time. It is likely to be the last Olympic Games for both the players, and they will be keen to bow out with top honours.
Dan had to work hard against talented Indian shuttler Kidambi Srikant to make it to the last four, while Lee made it via a straight-sets victory over Chou Tien-chen of Chinese Taipei. Despite the Chinese player holding a major advantage in the head-to-head record, the Malaysian star has won their previous two meetings, at the China Open and the Asian Badminton Championships.
It makes for a fascinating clash, with both players eager to get one over their opponent. Chong Wei has admitted that from now on it is a mental game as much as it is a physical battle as the two stalwarts of singles badminton take their final shot for a chance to make the final for a third consecutive time.
