Nhat Nguyen progressed to the last 16 of the Badminton World Federation World Championships on Tuesday after a brilliant defeat of English number one Toby Penty.
Nguyen had an encouraging Olympic Games in the summer, just failing to make it to the quarters after losing a three-game thriller against 10th seed Wang Tzu-wei.
The 21-year-old is continuing his strong 2021 in Huelva, Spain, where he took 55 minutes to overcome Penty 2-0 (21-17, 23-21).
