Im seriously not sure selling onana and branthwaite is enough. Remember we have been borrowing from 777 on a monthly basis to keep us going. From a wages POV they aren't even at the pointy end of our wages scale and yes, we are likely having gomes and alli's wages falling off but we have a lot more players to pay plus staff plus operating costs plus loan servicing.
We also have to pay for Beto this year too (circa 30m).
Even the cost of replacing those two will eat into a lot of the funds from Branthwaite and Onana (after the sale clause is paid to his former club). Keep in mind they will need to be of a reasonable quality I mean id play for about 100,000 a year (not a week) but im not sure id help us stay up.
We can be run sustainably but a significant restructure needs to take place. Moshiri has mismanaged the finances so bad as we will need to actually pay money to restructure. In another post I think we'd probably need to raise 250m from player sales just to have a shot at reorganising everything.
