An Se Young is relishing facing Akane Yamaguchi in the women’s singles semi-finals on Day Five of the YONEX All England Badminton Championships 2024, writes Milly McEvoy in Birmingham.

Defending champion An of Korea beat Yue Han to advance while Japan’s Yamaguchi knocked out Gregoria Mariska Tunjung.

The two will go fourth on Saturday as the Utilita Arena drops down to one court.

"After every win I always look forward to the next one, to be able to play against Akane tomorrow, makes me very joyful and happy," An said.

"With Akane, we are very friendly in our rivalry relationship. She always helps me to get better and see my weaknesses.

“There are areas I excel as well, but she allows me to see where my weaknesses are at."

The other game in the women’s singles last four sees Carolina Marin take on Tai Tzu Ying.

The pair have met 23 times with Tai winning 12 of them and the pair are split by just two places in the rankings.

The women’s doubles sees compatriots meet in both semi-finals as second seed Baek Ha Na and Lee So Hee of Korea take on defending champions Kim So Yeong and Kong Hee Yong.

“As long as we show what we know from Korea, it will be a close match tomorrow."

Rena Miyaura and Ayako Sakuramoto will face their Japanese teammates Nami Matsuyama and Chiharu Shida.
