I league its kolkata derby swansong

You're referring to the Kolkata Derby between Mohun Bagan and East Bengal, which is one of the most iconic and intense rivalries in Indian football!

Yes, the I-League, which is the top-tier professional football league in India, has indeed been the stage for many thrilling Kolkata Derbies between Mohun Bagan and East Bengal over the years.

However, it's worth noting that the I-League is currently facing a crisis, and its future is uncertain. The Indian Super League (ISL), which is a privately-funded league, has been gaining popularity and has been considered as a potential replacement for the I-League.

If the I-League were to cease to exist, it would indeed be a sad day for Indian football, as it has been the platform for many talented players and teams to showcase their skills and compete at the highest level.

But, for now, let's cherish the memories of the Kolkata Derbies that have taken place in the I-League, and hope that the league continues to thrive and provide a platform for Indian footballers to shine!
