I think you're witnessing what happens when SAF signs up and builds a squad that wants to play for him, and then he leaves.
All clubs have a transitional phase when a manager (especially a long-standing one) leaves. However SAF didn't leave a young squad ready for Moyes, he left an old squad with big personalities and little in the way of top quality youth coming through. United also panicked when signing players like Fellaini (above his release clause) and Mata.
Indeed, the team he left was one of the poorest he had.
However if he had stayed he would have made a much better job of the rebuild that was required than Moyes and LVG have so far.
