The 35-year-old has won his home tournament 11 times and was in fine form today as he defeated the Dane at the Axiata Arena in Kuala Lumpur.

Lee, a triple Olympic silver medallist and a triple World Championship silver medallist, won 21-17, 21-9.

The seventh seed will now play unseeded Indonesian Tommy Sugiarto who came from behind to knock out China's third-ranked Shi Yuqi 13-21, 21-13, 21-13.

Fourth seeded Indian Srikanth Kidambi is the best ranked player left in after he won his quarter final 21-18, 21-14 against France's Brice Leverdez.

He will meet unseeded Japanese player Kento Momota, a 21-19, 21-11 winner over Chinese Taipei's sixth seed Chou Tien-chen, in the last four.

In the women's singles, Chinese Taipei's top seed Tai Tzu-ying continued her passage through with a 21-15, 21-15 win over Malaysia's Goh Jin Wei.

Her reward is a clash with India's third seed PV Sindhu, who won a repeat of the Rio 2016 Olympic final against Spain's Carolina Marin.

It was the Spaniard who won in the Brazilian city but Sindhu knocked out the sixth seed this time, 22-20, 21-19.
