After succeeding Sir Alex Ferguson, Moyes was axed after just 10 months at the helm.
During his disastrous spell in charge, very little went the Scot’s way.
Moyes saw a lot of prospective deals in his first window as United boss slip through his hands before he lavished £27.5m on Marouane Fellaini.
But former United assistant manager and player Giggs reckons Moyes should be absolved of blame as he didn’t know what he would be working with squad wise.
“The recruitment in that first summer under David Moyes didn't go to plan. I don’t blame David,” Giggs told the Daily Telegraph.
“He came in without any of the inside knowledge about how the squad worked: when certain players needed resting, who was right for which game, who needed to be moved on and who needed to be encouraged.
“Those of us who had lived through it could help him a bit, but a manager has to acquire that knowledge over time.
“Signing Marouane Fellaini so close to the deadline that August, the club’s only major deal in a summer when we needed two or three big names, suggested that things were not running smoothly.
“United had signed players late in the window before – Dimitar Berbatov in 2008 springs to mind – but this time was different. This time it was more of a panic.”
