"SAINA NEHWAL - The former World no 1 badminton player. An Indian girl. An inspiration to millions. A youth icon in the truest sense. @NSaina," Shraddha posted.
"Her journey to the top has been fascinating and I am honored to be given this opportunity to play her in my next film 'SAINA' (sic)."
The 30-year-old actress, who is also part of another biopic "Haseena" based on Dawood Ibrahim's sister Haseena Parkar, said "Saina" is going to be her most difficult film till date.
"Saina" will be directed by Amol Gupte, who has helmed "Stanley Ka Dabba" and "Hawa Hawaai".
