This is a myth that likes to be peddled, the notion that we played shite football. We used to, but 06/07 onwards we played some very good stuff, but equally could play long too. We had a very good mix.
I think everything boils down to the fact that while Moyes did a very, very good job with us - and I'd never seek to deny that - he never won anything. That's a problem when you go to a team which has won things constantly for many, many years and is used to winning. While you'd expect there to be a transition and them perhaps not to be seriously in the title race this season - I imagine most fans would accept that - the amount he's taken them backwards is absurd. He hasn't got a winning mentality and that is proving a serious problem. This is the man who described going to places like Stamford Bridge and Old Trafford as "taking a knife to a gun fight" and "you just hope to get out of alive."
The second major mistake he has made IMO (general on-pitch questions aside) is getting rid of Fergie's backroom staff. Really don't think that was a wise move in the slightest.
Sign of insecurity.
