"I have always maintained that even when she won in 2013 or 2014 (back-to-back world championship singles bronze medals) Sindhu is still some time away from being her best. I maintain that even now that she has the potential to do even better," said the former All-England men's singles champion during an interaction with the media here.
He was also happy with Sindhu's performance at the year-ending World Super Series Finals in Dubai where the 21- year-old reached the semi-finals before losing to South Korea's Sung Yi Hyun after avenging her defeat in the Rio Olympics final to Spain's Carolina Marin in the group stage.
"The year has been fantastic. She had a chance to play Marin (in Dubai) and beat her. It's good. The way she qualified for the Super Series finals was also very creditable as she had to win and play the finals. In the last three tournaments she took part in there was one win, one runner up and one semi-final. I'm happy the way she has played overall."

For Gopichand, it's important to see what she has
already achieved rather than rue over what she hasn't.
"She is just 21. She has achieved World Championship medals, has won medals in Commonwealth Games, Asian Games Asian Championships and Olympics. I would rather stick to what she has achieved than what she has not."
He also saw intense rivalry brewing up in women's singles with Sindhu in a mix of young and talented players.
"Women's singles badminton is a very challenging event with a lot of countries with young, exciting and various types of players dominating the scene. If we need to consistently win we need to change our style and keep adjusting to different styles," the Hyderabad stalwart said.
Gopichand was also glad that former world No.1 and 2012 Olympic Games bronze medallist, Saina Nehwal, is back in action after being laid low by a leg injury with which she struggled to compete in the Rio Games and made an early exit.
"It's great to see her back and give some good performances in China and Hong Kong. I am sure the coming days will show us even better signs. She has played three back to back tournaments which obviously shows she has recovered very well (from her injury)," said Gopichand.
While conceding the men have been inconsistent, he blamed the surfeit of tournaments they had to play for achieving Olympic qualification for their fitness problems.
"It's been a challenge. Many of them have played many tournaments, trying to qualify for the Olympics, that actually somewhere made dents in their fitness. I am happy at the end of the year that we had a quarter final result (K Srikanth) in the Olympics which was important.
"They all have played very well in different times and it augurs well for Indian badminton. Hopefully, we will get consistency (in future)," he concluded.
