Of course that's why I said they were very rough figures, however the costs wouldn't increase at anything like the rate that the revenue would.
What about the naming rights? That's expected to be a further £10m+ which brings you to the ~£20m.
I'm sorry you have confused me, first you said the ground repayments by your rough workings would be 28 million per year and the additonal revenue it would bring would be 37.5m by my maths thats only an extra 9.5million per year to spend on players. Of course without the extra carlsberg these fans would buy.
