That’s exactly what he’s done. It’s called a leveraged purchase. You borrow money to buy the club (or, in our case just the fixed assets but that’s semantics really) and use future income to pay off the debt.
It’s perfectly legal, Glazers bought Man U that way and I think ALK have done similar with Burnley.
PA owns the club. All of it. That means he can run it at break even, run it at a loss (providing he has the funds to do so) or run it to make a profit that he takes from the club. It’s entirely his choice because it’s a business, his business.
