Ferguson hand-picked Moyes to take over from him at Old Trafford after his retirement at the end of last season, but the former Everton boss was sacked earlier this week after a disastrous campaign.
The champions are currently seventh in the table, and are a whopping 23 points behind leaders Liverpool after suffering 11 defeats this term - their most ever in the Premier League era.
According to The Mirror, Moyes feels let down by Ferguson after the legendary former boss neglected to offer his support during Moyes's tough periods at the helm.
Moyes believes that Ferguson deliberately distanced himself from his chosen successor as results began to suffer.
Meanwhile, Ryan Giggs has taken over at United until the end of the season.
