Olympic Silver medallist P V Sindhu on Wednesday said she still has lots to learn and needs to add a few more shots to her repertoire to dominate world badminton.

With Silver medals at all the major events, including the Olympics, World Championship, Asian Games and Commonwealth Games, Sindhu has been a formidable force in the world in the last three years.

But the world No 1 tag has eluded her with Chinese Taipei's Tai Tzu Ying stamping her authority at the top with 14 title triumphs since 2016.

Asked if she needs to add strokes and deception to dominate world badminton, Sindhu said: "Definitely yes. It is only the starting for me. I have a lot more to learn. I have good strokes but I have to keep learning new strokes everyday.

"But I think only one player can't dominate badminton, because the game is changing right now as a lot more players are coming up. Also on a particular day, you have to be 100 percent, can't be even 1 % here or there, if you count 1 to 20 in the world, all are of the same standard, so have to be focused all the time."

One of the favourites to claim the All England trophy next month, Sindhu said she is working hard to break India's 18-year-old title jinx at the prestigious tournament.

"After this week, only two weeks will be left for the All England. I know Carolina Marin will not be there (due to injury) but it won't be easy, because there are some very good players and on that day who gives best will win," Sindhu said.

"Each round will be comparatively very tough. Each point is important for me. I am playing Sung Ji Hyun in the first round and it would be important for me to focus from the first round," added the 23-year-old, who had reached the semifinals of the All England Championship.

Asked about ending the title drought for India, Sindhu said: "Hopefully yes, I think it will be really good if someone breaks it someday and definitely we will work for that."
