Fortunato Franco, one of the key members of India's Asian Games gold-winning football team in 1962, died on Monday at the age of 84.
The AIFF confirmed the news of his death but did not specify the cause of his demise. He is survived by his wife, son and daughter.
One of India's finest midfielders, Franco was a part of Indian football's golden era between 1960-64.
He was a part of the 1960 Rome Olympics squad but didn't get a game. However, he was an integral part of the 1962 Asiad gold winning team in Jakarta.
He made 26 appearances for India, including the 1962 Asian Cup, where India finished runners-up, and was part of the silver and bronze-winning sides in the 1964 and 1965 Merdeka Cup.
His best performance was in the 1962 Asian Games, where Indian football witnessed its finest hour, beating South Korea 2-1 in the final in Jakarta in front of 100,000 people.
While the more illustrious quartet of PK Banerjee, Chuni Goswami, Tulsidas Balaram and Jarnail Singh hogged the limelight, Franco would forever be remembered for providing the assist for Jarnail to nod home the winner.
At the domestic level, Franco, a Goan, played for the Tata Football Club in Mumbai. He later worked in the company's Public Relations department for four decades before retiring in 1999.
He was one of the biggest names in Maharashtra football, having captained the state for eight successive years between 1959 and 1966 in the Santosh Trophy, and was the architect of their title triumph in 1964.
During his last years in competitive football, he played for Goan giants Salgaocar, but a knee injury ended his career before he turned 30.
Had Franco not retired from international football in 1965, many old timers believe that he was a contender to become India captain for the 1966 Asian Games in Bangkok.
"It is devastating to hear that Mr. Fortunato Franco is no more. He was a member of Indian football's golden generation who played a stellar role in India helping India win the Gold Medal in 1962 Asian Games," AIFF president Praful Patel said.
"His contribution to Indian Football can never be forgotten. I share the grief," he added.
AIFF general secretary Kushal Das said: "Mr. Fortunato Franco will be alive in his achievements. He played a massive role in India winning the Gold Medal in the 1962 Asian Games.
"He was a legendary footballer who has been an inspiration to so many generations. My condolences to his family. We pray for his soul to rest in peace."
