RIO DE JANEIRO: The real challenge begins for Lee Chong Wei after he easily advanced into the Rio Olympics men's singles quarter-finals on Sunday.
Singapore's Derek Wong was beaten 21-18, 21-8 in 35 minutes as Chong Wei, as expected, topped Group A to advance into the quarter-finals. The Malaysian received a bye in the last-16 stage.
Up next for the World No 1 will be either Taiwan's Chou Tien Chen or Hong Kong's Hu Yun on Wednesday.
"It is good to have finished the group stage without any problems and I can now focus on the knockout stage.
"I felt good on court even though my opponent didn't offer too many challenges," said Chong Wei at Pavilion 4, Riocentro.
Chong Wei said he has adapted well to the conditions and having extended breaks between his matches wasn't too much of a problem.
"I would prefer to play daily and finish the tournament but I just have to keep my focus."
Chong Wei beat Soren Opti of Suriname on Thursday in his opening clash before playing Singapore's Wong on Sunday.
It will be another two-day break before his quarter-final.
"I just have to cope with it. It's the Olympics and I want the gold so I have to accept all challenges," said Chong Wei.
