It's obvious what will happen. They will be allowed to take over, will get a rush of headlines from the News proclaiming a new era and being a guiding light showing football clubs how to behave. They will be called the future of English football (lol.) They will get decent attendances for league two and as such will be able to get some half decent players in league two. I expect them to get promoted within three years to much fanfare. From there it gets harder I suspect that they would find that league one will be their level. Possibly they will get a year or two of championship football in the future but it will be lower championship and probably relegation again. The bad bit for them is that the longer they stay down and all the teams around them stay more successful, the less fans they will eventually get.
Perhaps the most amusing bit will be that they will go on about us being jealous because they own their club and how much better it is whilst we will no doubt be above them for a generation.
