2.85m is a lot.. however, how much do you think it would cost to buy the amount of land required for your scenario? How much would it cost to implement pitches that are good enough in quality to train on? How much to build facilities such as a gym, maybe a restaurant, changing rooms etc… let alone the cost to maintain.
I saw it mentioned about 4G. Believe me that it’s not a cheap option to input a 4G pitch, and they do require regular maintenance which is also costly.
If the bros have the funds then ROKO could work. At least we’d have a home that is fit for purpose to train the first team. It would also be an income stream.
