For Mohun Bagan and East Bengal, winning the Calcutta Football League (CFL) title holds more importance than winning the I-League at the national stage. The CFL is older than the Federation Cup and the National Football League -- the predecessors of the I-League.
Indian Super League (ISL) doesn't even come in the scene.
The CFL which first played in 1898, resumes in its 119th edition of the football competition this August. Mohun Bagan and Mohammedan Sporting remain the strong teams, while East Bengal remains the most successful team in the history of the Indian football competition.
They are chasing an eighth-successive title at Calcutta Football League and their 39th overall.
Mohun Bagan, meanwhile, is chasing their 30th overall title.
