OK, I just wanted to make sure I understood you. In that case you are suggesting something as ridiculous as I thought.
It's ridiculous (and I'm being kind here using this word, as you've never actually been rude to me) on many levels.
No bank is going to lend a football club with relatively tiny annual profits (which is what ours were in the tiny old stadium) 1bn pound to spend on "some" footballers, that might or might not actually help us win something.
Even if you could find some corrupt bank employee, at a really, really, really stupid bank in some far off land to lend you 1bn to spend on some footballers, that might or might not make you a pretty good team, you'd be about 970m over the three year (not one but three year) FFP allowance for owner injected capital for non infrastructure purposes. So even if that team won the league, (and even ManC having spent 2bn haven't managed to do that every year) it would then be banned from the CL and all it's revenue, so we would now be in a tiny stadium generating very little revenue from match day, food, beverages, merchandise etc and wouldn't even have CL revenues - to help pay back our 1bn bank loan.
But lets burrow deep down into the habit hole of this totally ludicrous scenario and say we found the crazy bank to lend us the money and and zeppelin crash lands on UEFA HQ and kills everyone in the FFP department....what if after spending 1bn - and lets remember ManU have spent 1bn plus in recent years and still failed to won anything this season - and managing to somehow persuade PSG, Barca, Real, Bayern to sell us all their best players, and persuade those players that playing for Spurs at 36k WHL is where they want to be, and then what if we don't actually win the league, like ManC didn't win the league this year, or ManU didn't win the league this year (or anything) or even worse, what about if we get the 1bn and we spend it really badly - you know, like Barca have done recently? What then?
What you are suggesting is just totally ludicrous and impossible nonsensical stuff.
The only way we start spending even close to that - and even PSG and City have had to spread it out over a bunch of years - is if we get taken over by a gulf state wealth fund - because even being taken over by a multi billionaire individual wouldn't get him round FFP, for that you need to be able to inject massively inflated owner/related sponsorship, and even that is being scrutinised and both City and PSG have been fined (big deal I know)..
That is why we had to b build the stadium first. We will still never be (unless we get bought) that PSG/ManC model, even with the stadium, but it at least allows us to generate much bigger revenues, which allows us to invest (and stay within regulations) in the football team.
