Ten years after the formation of the National Football League, the All India Football Federation, the governing body for the sport in India, decided to reformat the league as the I-League in an effort to professionalize the game. However, during the following seasons, the league would suffer from a lack of popularity due to poor marketing and poor quality of football.
