I totally agree with this. MU never had the debt hanging over them when they've dipped in form before i.e. not winning the title for 3 years between 2004 - 2006. If that happens again, that debt is going to start to exert some serious gravity. Jose pretty much nailed on Fergie replacement though you would think, the guy is practically handed his CV to them already!
As I said yesterday, Fergie wants Moyes as his successor and he'll have a lot of clout.
If it's not Moyes, I really can't see it being Mourinho. United are going to be strapped for cash for the foreseeable future and I can't see The Special One going to a club that's been a major player to preside over its decline.
I can see him going to City though ...
