It's honestly hard to say. We're focusing on expenditure, which is a significant amount, but they're a big club, so will have a fair amount of income as well. And I'm sure some of their players must have market value.
@Sinner: which of your players are worth anything and how much roughly would you expect to receive for them?
Next season should be very straight forward for them in my opinion. The following season, however, is a different matter entirely. Increase in costs (transfer fees and wages) means that they won't have more a few seasons in the Championship to gain promotion to the PL. Any longer and they will probably start to worry.
SD and CM have talked about not wanting to deal with agents and stomping out player power. Lovely words, but to me that sounds more like a fantasists dream than anything.
