A weak defence was the reason behind PV Sindhu’s slip in performance early in the year and the COVID-induced break has helped her address the flaw and also work on her motion skills ahead of the Tokyo Olympics, said India’s foreign coach Park Tae-sang.

Park, 42, who was roped in for India’s men’s singles players in 2019, has been training Sindhu following the departure of fellow Korean coach Kim Ji Hyun after the Basel World Championship two years ago.
