In year end 2019, broadly speaking and ignoring player sales and purchases, you broke even.
Turnover was £140m, wages £111m, other opertaing costs £21m, interest £6m profit £2m, in round numbers.
(You then spent a vast sum in player signings - £90m+.)
2020 is going to be less profitable. Factor in a £10m drop from coronavirus and whatever you lose on gate money, and a further drop in TV money from finishing lower down the league. Wages may reduce depending on bonus structure - Burnley players, for example, get about a quarter of their wages as a bonus for staying up. If we go down, so do wages.
So if you get relegated at lose about £70m of turnover, you have to make it up by (a) cutting wages, via sales or by relegation clauses. (b) cutting operating costs - but you're only playing round the edges there. (c) selling players. (d) money from owner. I would suggest (e) loans but you won't be in a good position to borrow.
And it appears that the first £16m of player sales are already mortgaged, and that you still owe in the region of £50m to other league clubs for incoming transfers signed before last June.
I think you need a big cash injection from the owner. Who you already owe £110m to.
