Who in their right mind would spend £2-3bn buying LFC, only to have to inject another likely £1bn in player purchases and then have prop up the club every year after wages likely outstrip income... and all without loading any of that debt on to the club or without any chance of getting a financial return on the investment.
I don’t even think the current owners of Chelsea, PSG or City would even think about doing something as stupid as that - they bought the clubs cheaply, in much the same way FSG did, so they could grow them.
