Five-time champion Lin Dan and top seed Son Wan-Ho set up a semi-final showdown at the badminton world championships after coming through their quarter-final matches on Friday.

Chinese star Lin, who won the last of his world crowns in 2013, overcame Hong Kong’s Vincent Wong Wing Ki 21-17, 21-18 in Glasgow.

“I really enjoyed today’s match,” said 33-year-old Lin, who was taken to three games in his two previous matches. “I am very happy that I managed to minimise my opponent’s performance today. It was good to get it done quicker today and I expect to perform fully to my 100% tomorrow.”

Son, the world No 1 from South Korea, beat India’s Kidambi Srikanth 21-14, 21-18 to guarantee his first world medal. “Today I am really happy with my performance because this is my first semi-final,” said Son.

“Srikanth was coming back in the second set and won seven points in a row and I was getting very nervous. I was just telling myself, ‘One point at a time.’ If I had lost the second one, who knows what might have happened?”
