PV Ramana, father of Indian badminton superstar PV Sindhu said on Monday he was disappointed that her daughter lost in the World Badminton Championships final and added that it was for the first time he saw her crying after the match.

The Rio Olympic silver-medallist gave it her all in the breathtaking final of the women's singles event, but she had to eventually settle for the silver at the World Championships.

In a close summit showdown that lasted for one hour and 50 minute, the longest match of the tournament so far, Sindhu lost 19-21, 22-20, 20-22 to Nozomi Okuhara of Japan.

"I am a bit disappointed about the loss in the finals. But she exhibited a fighting spirit against Okuhara. I am happy that she (Sindhu) fought well till the last point," Ramana told ANI.

"First time I saw Sindhu crying that she has lost. It is good that both Okuhara and Sindhu have shown the world their class of badminton. I am happy with the performance of my daughter," he added.

Ramana, who himself is a former volleyball player, further insisted that he was overwhelmed with the love and support that his daughter was getting from the people of India.

He, however, said that for a player a gold is a gold and silver is a silver.
