I reckon it's an extremely simplistic view, ignoring several key factors. First of all, Moyes took over a squad that was in a much better state, secondly the transfer budget claim is overstated. Moyes came up with a list of transfers targets that was naive at best, like believing that there was a chance Ronaldo would return, deciding it was important to pursue Bale until he was officially a Real Madrid player, the interest in Fabregas, deciding to shelf the interest in Alcantara because he hadn't had time to personally scout him and he was unsure of his qualities...Unfortunately, all this coincided with Woodward being a complete rookie. Completely unrealistic deals, while Moyes was afraid of how it would look if Fellaini was our first signing, which resulted in us waiting until deadline day before signing him. Adjusted for inflation he was almost £60mill. Moyes, the genius that he was, then decided to play him as a defensive midfielder, giving the opposition a highway towards our defense, essentially exposing every weakness in Rio and Vidic instead of protecting them and using their strengths.
He just didn't have a clue whatsoever about how he wanted us to line up, which explains the absurd tactics changes from possession style football, crossing only, counter to hoofing.
Don't think he ever understood the size of the job, easily shown in his press conf after the Olympiakos match.
Ole inherited a mess, a squad in dire straits and no clear direction. While i doubt he's going to be the one in charge in 2 years from now, i'm convinced that the changes he's helping implement is going to lay the foundations for future success.
