It's a bit of everything really. Fergie could get the best out of them, the lack of being able to motivate themselves to play well for a guy like Moyes when you've been managed by Fergie for so long, Moyes having way too many brainfarts, some guys needing to go. Plus, their transfers were shit too, Fellaini was crap. Nothing went right in pretty much any way last season.
Lol if Moyes causes any of the top sides to drop points. Probably not, he was never that great for Everton against the top sides in England.
