Moyes' first transfer window was a complete disaster. Fellaini was £4m over priced, the release clause actually expired during the window which Moyes had full knowledge of. They pursued pie-in-the-sky players, Modric, Alonso, Fabregas being the most prominent. They were never going to join.
The attempted signing of Herrara would have been a good buy, but it is still unclear why it failed. Moyes never wanted Thiago and it was taken from under his nose in the end. Ever Banega of Valencia would have been a good option; as was Koke.
One of the largest indictments of Moyes' judgement is not bringing Barkley with him to United. He had a gem under his nose, he barely played him for Everton and now he is excelling for Everton.
I do feel sorry for Moyes, he looks so frustrated on the bench. It may have been a promotion too far.
