I think most people are just fed up of the awful, boring, defensive minded football we've been served up the last few years so every one favours a manager who's going to bring excitement. Moyes is a good manager but the football isn't going to get the pulses racing at all and he won't get to choose the players we sign (if we sign any at all).
I'd welcome him though. I'd welcome any one not named Alan Pardew.
