Hyderabad: India might be celebrating a world champion in P V Sindhu right now but national badminton coach Pullela Gopichand feels there are reasons to be worried about the future as the country has not "invested enough in coaches".

Sindhu, who is also an Olympic silver-medallist, became India's first world champion in the sport with a straight-game triumph over Japan's Nozomi Okuhara in the summit clash on Sunday. She returned to a frenzied welcome on Monday night. However, Gopichand feels the country needs to wake up to the fact that there aren't enough coaches to handle the talent that is rising. "...we have not invested enough in coaches," he said here with Sindhu by his side at a press conference on Tuesday night.
