China's double Olympic champion Lin Dan cruised through to the second round of the Malaysia Super Series Premier but reserved praise for an opponent he had not heard of before the match at Stadium Malawati in Shah Alam.
The 32-year-old, the men's singles champion at Beijing 2008 and London 2012, came past Malaysian qualifier Chong Yee Han 21-10, 21-15.
"I did not even know who Yee Han was but I saw him play against Kenichi Tago in the qualifying match," said Lin after his first round success.
"I was impressed when he played Kenichi and also when he played against me.
"It looked simple but it is due to his lack of experience.
"He needs more exposure and play in more tournaments."
Lin, the number four seed, will be one of the contenders for success after winning the prestigious All England Open, another Badminton World Federation (BWF) Super Series event, this year.
China's number one seed Chen Long is also through after beating Germany's Marc Zwiebler 21-19, 21-15, while number two ranked Lee Chong Wei of Malaysia delighted his home fans by defeating Japan's Takuma Ueda 21-11, 21-8.
Japan's Kento Momota, the number three seed, was a 21-19, 22-20 victor over India's Prannoy Kumar but has now withdrawn.

In the women's draw, Spain's top seed Carolina Marin beat Yip Pui Yin of Hong Kong 21-13, 21-15 to advance into round two.
