Agreed, you're right, I realised that today.
Spurs are posting losses, but a lot of the deductions don't count towards PSR, so we are absolutely fine in PSR terms, and thus if Spurs (Levy) had (or finds an investor with) hundreds of millions, we could invest that money if we could reliably claim the money was spent on sponsoring the ground or whatever.
But in terms of the current Spurs and Levy, we do plough all money back into the football team and do spend what we bring in, and have spent huge sums of money on "fees + wages".
