Personally after reading up about all this crack at the scum i think this has something to do with money. Fergie came out and said he would be signing a few players this summer and spending money, then their new director i think it was came out a week later and said they wouldn't be spending much on transfers at all, then i heard Fergie was told to retire and it was on this new directors advice that he resign and get in Moyes who can work well on a budget, and then you have the sudden rise on the stock exchange, maybe money is getting tight at Old Toilet? This is all based on rumours, hearsay and from what i've read so could and probably is a million miles off but you never know
Won't be surprised with American owners having similar strategies and still surprised that they didn't go for higher calibre managers, but, if it is Fergie's choice, then I will wait a bit before concluding. He has got most things right in his career.
