India shuttler PV Sindhu has endured a torrid season that ended with her surrendering the BWF World Tour Finals crown recently, but chief coach Pullela Gopichand is not concerned with the dip in form despite next year's Tokyo Olympics (July 24 to August 9) fast approaching.

Sindhu, 24, who defeated Japan's Nozomi Okuhara in Basel, Switzerland, in August to became the first Indian world champion, crashed out of the year-ending event in Guangzhou, China in the league stages.
