Released by Blackpool this summer, Chopra - whose father is Indian - insists he cannot wait to begin a new chapter in his career.
"It's an amazing feeling and I am very excited and privileged to be part of this fantastic opportunity to develop football in India," he told Sky Sports.
“After playing in England for 12,13 years now I'm ready for a new challenge. I’m looking forward to the Indian Super League and getting into the I League after that.
“In the future I'd like to open up academies and hopefully one day represent India which has been a dream of mine for some time. My desire to play for India is well known and now I must do all I can to prove my ability and show fans that I'm worthy.

The 30-year-old will take part in Thursday's ISL draft for the eight team inter-city league which is the brainchild of the All India Football Federation and its marketing partner IMG.

“The Indian Premier League cricket is on Sky (next year) and is really big,” he added. "While the sport has become increasingly popular all over the world the ISL will put Indian football on the map. The Super League is only just kicking off so I think in years to come it will turn out to be a bit like the IPL.
“I think people will start following football more, watch it more and start wanting to play it more."
Asian Football Awards founder and football agent Baljit Rihal from Inventive Sports added: “I have worked closely with the SME Group and IMG to ensure that Michael is part of what we believe is a poignant moment in the history of Indian football.”
