I see a lot of people finally talking about new stadiums to be built even on X. This is pretty awesome given we almost didn't even get a league, but some reality checks are in order. Some of the clubs are barely getting by, they still don't make any profits. While someone like JSW absolutely has the money needed, investing tens if not hundreds into a new (even a cheaper temporary one) stadium will be the last thing they would want to do right now before the league gets stable and starts delivering consistent and growing income. The league has to be financially attractive and strong in stability and longevity before clubs will think of any assets.
But, for long term financial health, having your own stadium or atleast having full commerical control and naming rights over one is absolutely key for clubs a few years down the line once the league is stable. It adds a huge chunk of revenue, especially if you sell naming rights to the stadium as is customary in europe or US. And the ability to fully commercialize it the way they see fit will be a huge income source. Think club museums, (for heritage/successful clubs), proper food and beverages, booze, VIP lounges, basically making money out of a great match day experience for people who can afford to pay. That's where western clubs make the maximum money from.
As to how they'd get their own stadiums, there's always the option of buying land outside the city but that would be too far away unless there's a metro connection (if there is it would again make land pricier).
Finding new land inside the city is lowkey impossible. What clubs should look into doing is redeveloping existing football grounds in partnership with the local government and then work out a long term lease deal. MFA is a neat example (although they didn't get a lease, its the closest to having your own football only stadium at the moment)
BFC could redevelop the BFS. Get the issue sorted in court and hopefully the KSFA gives fresh tenders. And does it properly this time ffs. (OP is still salty about this.)
Idk why SC Delhi aren't already using Ambedkar stadium, it recently got a renovation as well. If its still not upto ISL standards I imagine it wouldn't cost much more to get it upto that level.
Mohun bagan and east bengal combined can certainly get land and build their own stadium (a la san siro) and play only the derbies at the salt lake. Two clubs will make the affordability much better. They could maybe use their own current grounds, but they don't really own it, the army does. And every small upgrade is a huge hassle to get permission and they'll never get full commerical control. Its not worth it otherwise they would've done it by now.
Mumbai already have the MFA. Selling that out first is a priority. Post that, it can always be expanded there is enough room there for a 15k stadium
Punjab's new deal with a university is a decent option for clubs from smaller cities. Partnering with a university sounds excellent. You split costs and the university gets some A tier sporting infrastructure. If it actually goes through is another question. Inter Kashi announced a similar thing last year but nothing has come off it so far so I'd be sceptical until there's some work on the ground.
Kerala's new owners certainly have the money. And the state loves football unlike any other. With enough pull, I don't think it'd be too hard to work with the government and redevelop one of the athletics stadiums into a football only stadium or even build a new one in Kochi or Kozhikode or any other major hub. All it needs is drive and intent. I saw news of them having stadium plans but I'll believe it when I see work on the ground.
Only NEUFC are already sorted ig. They'll have two football stadiums to pick from 2 years down the line by the looks of it. Only thing they need to do is try and get commerical control over one of them.
