That's despite United sitting sixth in the Premier League, being on the brink of a Champions League exit, having suffered embarrassing defeats in both cup competitions this season and being thrashed 3-0 by fierce rivals Liverpool on Sunday.
Howard, interestingly enough, commentated on that game for American broadcasters NBC - but the shot stopper still feels Moyes will get things right at Old Trafford with time.
The 35-year-old, first of all, insists Man United fans should not worry about the club's transfer plans next season, predicting a big-spending summer for last year's league champions.
“Absolutely. Any time you are at club you want your biggest players in order to attract other bigger players and they have done that so I am certain they will have a pretty good summer spending money," Howard told ESPN.
It might just be out of loyalty to his former boss - but the American feels Moyes has done little wrong during the season. Instead, Howard blames United's struggles in the transfer market last summer.
“The teams around them that are competing over the summer brought in five, six, seven players of quality, spent near 100 million pounds and for whatever reason Manchester United only brought in one player who we know well, [Marouane] Fellaini, but has been often injured this season so if you do the math, that doesn’t bode well," he explained.
So what of the future for Moyes and Manchester United?
“I think this club will succeed and David Moyes here, given the right time, will be a huge success,” the 35-year-old argued.
“David Moyes never takes a backward step. He always believes that he can do the right things. He believes in his methods, he believes in the players that he brings to a club and that makes for a really good working environment over a long period of time.”
Not everyone, of course, is of that opinion these days.
Is Moyes still the right man to take Man United forward?
