I'm not denying PSG are capable of outspending us and nor am I denying PSG are capable of offering higher salaries. My point was made a complaint that the Glazers were stingy, when they spent close to £600m in the last 4 years, without many big departures. I think it's a common myth that because Fergie and Gill didn't want to pay extortionate prices to players/agents, that it was the Glazers fault. We've seen these past few years it's not the case and when we need to spend money, they are more than willing to approve it.
Regarding not being able to match Neymars salary, I'm not entirely sure i'd want to... The transfer fee and the post tax earnings are crazy and appear to have some dodgy links to the Qatar World Cup etc, I doubt it's all above board but that's another story. I don't think you'll see any other team pay that sort of fee or wages for a top player unless there is something dodgy going on in the background.
Regarding the debt and making us richer... yeah the Glazers approach to buying the club was frowned upon but since they have taken over we have grown an enormous amount in terms of commercial revenue, they are savvy business people and we are earning a shit ton of money from legitimate sponsors who want to be apart of the United brand.
