Hyderabad, Aug 9 - World No. 1 Lee Chong Wei of Malaysia will look to renew his rivalry with defending champion Lin Dan of China when the World Badminton Championships begins here Monday.

Olympic champion Dan and Chong Wei share a sizzling rivalry and can run into each other in the men's semi-finals at the Gachibowli Stadium here.

Though Chong Wei is the top seed in the World Championships, Dan, who is seeded fifth, has been the Malaysian's worst nightmare.

Chong Wei has defeated Lin in their last meeting, the Swiss Open in April, but the Chinese ace has always enjoyed a upper hand in the major tournaments.

Wei, on the other hand, is still to win a World Championship or a Olympic gold. The 27-year-old's Olympic dreams were crushed by Dan in the Beijing final last year.

'It still hurts. I have not won a World Championship or an Olympic gold. That is a motivation for me this time,' Choing Wei told reporters.

Chong Wei, a bronze medallist in 2005 in Anaheim, said this time he is determined to better his best performance in the world meet.

The Malaysian will open his campaign against Germany's Dieter Dromke, and could meet his first big hurdle in Vietnam's Nguyen Tien Minh in the third round.
