PETALING JAYA: Taiwan’s Wang Tzu-wei and Denmark’s Magnus Johannesen’s huge upset wins in the French Open prove that the duo can play the role of spoilers to the big guns ahead of the Paris Olympics.

World No. 27 Tzu-wei pulled off the biggest surprise in the French tourney so far when he stunned Denmark’s world No. 1 Viktor Axelsen 21-12, 21-17 in the second round at the Adidas Arena in Paris on Thursday.
