Gopichand has already said PV Sindhu will be a marked player at Tokyo 2020. I don't see Sindhu resting on her laurels. Sindhu is determined to work hard and is getting ready for tougher challenges ahead. Sustaining high pace consistently like Marin Carolina is dangerous and not recommended as injuries happen. We still don't know how long it will take for Marin to return and what her form will be in the future. Sindhu has a good record against Akane Yamaguchi though she lost the last 2 matches. I am sure she will have a strategy in place next time. Chen Yu Fei, Tai Tzu Ying are definitely going to go hard against Sindhu. Sindhu will work on improving her skills. Exciting matches ahead!
