I think the ManU job could quickly become a bit of a poisoned chalice. Think about it... anyone that goes there will be compared to Fergie. Look what happened to Rafa after taking over treble winning Inter... now magnify that by a 26 years! Plus, Fergie is staying on as a director.... so any manager taking over will have him breathing down their neck. I can see this becoming a high pressure situation very fast.
Nail on the head fella.
For all the talent that Chelsea & City have in their ranks, they've been [oops] of late - even title winners City last season were far from convincing IMO.
Squad mentality / direction goes a long, long way.
Fegie will haunt them regardless of who takes over - his personality will be gone from the dressing room, from the touchline, the media and the F.A. - he holds a lot of clout.
Man U will become a Chelsea / City / Arsenal type of team (hopefully) Win the league here, fight for fourth there... theleague is going to get interesting next term..
