The ISL is under a different system from the Indian First Division.At present, the Indian Super League (ISL) is in commercial operation. Due to registration and other issues, the champion of the ISL is not allowed to represent India in various Asian intercontinental competitions, that is to say, the Indian First Division I League will still represent India in Asian competitions. There is no promotion or relegation in the Indian Premier League.The home and away games system is adopted. The scoring method is three points for the winner, no points for the loser, one point for each draw, and the top four players in the league go to the play-off. Under rules set by the Indian Football Association, all 10 teams must employ a foreign coach and bring in four foreign players, including a world-class star, two foreign players and an Asian player.
