If £100m came in, it would mean we could sell players like Charlie Hughes and not have to worry about signing a replacement while simultaneously having to find quality for other positions as well.
Say Hughes goes for £20m in January. We then need to find a replacement who is ready for the Championship, fits the style of play we have and doesn't demand the earth in wages. That player costs say, £5m. The other £15m then goes into other costs - some of it will be wages, some of it will service debts, some will be spent on transfer fees (assuming we can spend money again by that point).
With an investor on board, we don't have to worry about servicing debts from the proceeds of player sales, nor do we have to worry about funding future signings or projects. Without one, we're wholly reliant on one avenue of income outside of Acun Medya, which is selling our best players.
If 100m come in you would not have to worry about Acun,we would have new owners, then worry about them instead.
