Football in India
National Football League, established in 1996 by governing body All India Football Federation (AIFF) was the first "semi-professional" football league in India. 
The League was renamed and restructured and the I-League was founded in 2006 after India's former top league the National Football League disbanded in a successful effort aimed at increasing the game in India. Links with clubs that were not in the I-League were maintained, and each season the bottom two clubs are relegated from the I-League and replaced by two from the I-League 2nd Division. The I-League is currently contested between 11 clubs. The Kolkata Derby in the I League (and other tournaments) played between Mohun Bagan and East Bengal is one of the most fierce rivalries in the world (featured in FIFA website) and one of the oldest derbies in the world (90 years). An average 80, 000 to 100, 000 supporters throng the stadium in this special fixture.
Bhutan National League
The National League is a standalone football competition, that operates as the highest level of football in Bhutan. It consists of six teams, four of which are based in Thimpu, with the remainder coming from other districts. The four Thimphu-based teams compete in Thimphu League, which was previously the top league in the country, but now serves as a qualifying tournament for the national league. Competing teams in the league play each other twice on a home and away basis. Previously, when the A-Division was the country's top league, all matches were played at Changlimithang, the country's national stadium, making "home" and "away" distinctions essentially moot. Whilst the Thimphu-based teams still play their matches at that ground, the regional teams maintain their own stadia and genuine home and away fixtures now take place.
