Moyes has endured a torrid debut season in charge of the 20-time Champions, with United currently 11 points behind Liverpool in fourth spot, and facing the prospect of a trophyless season, bar a miracle triumph in Europe.
But Neville believes Moyes will be given time and money to turn things around at Old Trafford, as the mega contract recently offered to Wayne Rooney proves.
“Everyone always wants to look for the one reason [for failure] and in football these days, if you look at most clubs, it gets put on the manager and they usually get sacked,” Neville said.
“Man United are very different and David Moyes will get the time he deserves to come to terms with things. It’s always been the same.
“Usually the manager is the fall guy for it and he’s the one who will get the most criticism. The club is huge and the task is huge but the club are supporting him by signing Wayne Rooney, Juan Mata and Maraoune Fellaini.”
And Neville believes the signing of Mata and Rooney indicates there will be further big money signings to come in the summer, despite his belief United will miss out on the Champions League this season.
“There is talk of more serious investment in the squad in the summer,” he added.
“Ed Woodward did his speech to the shareholders a couple of weeks ago and said there was a huge pot of money there to be spent and help Manchester United invest in the team and add to the current players they have got.”
