I think it is a matter of time, if not next season, the one after. Once they do go down I see them being down for a while. They are going to struggle to fill that ground even with cheap tickets and their wage bill is huge.I think it's bold to assume the playoff timeteams wouldn't struggle too (maybe less so Fulham).
They don't have the money to invest in the squad so they need to buy well buy well and hope DM can do a similar job that he did for Everton. I can't see it happening, best case is for them to scrape through each year.
