I mean this is the kindest way possible, but I think you are deluded if you think you can hang onto your most valuable players,
Pay them the going rate and service the stadium debt.
The multi use stadium thing is a pragmatic attempt to raise more revenue, although it does water down the sense of it being your home ground a bit.
But that alone isnt going to service the debt. As I said, I think you’ll either try and do something similar to Arsenal, ie qualify for the CL and sell your most valuable players. Or ENIC will sell the club and the stadium.
I wouldn't even say it was there home ground anymore, it belongs to the NFL and the plastics are allowed to borrow it every other Saturday.

It won't hurt the two Yid shysters.
