Proof of his stubboness on the matter can be seen already no? If Charlton and himself weren't so dogmatic in their principles of "We're Man Utd, we're not like these other.. lesser clubs, We're different, we're better" Moyes would be gone already, before tonight no?, considering there is literally zero indication of a turnaround on the cards, infact our form and results since the new year has seen us reach new lows and still not appearing to have hit rock bottom.
Adding in the weight of Sir Bobby going on about still being convinced of Moyes then your instinct would lead you to believe Sir Alex and co still believe in this mess, pride comes beore a fall me thinks.
