The Manchester United boss has come under a lot of pressure for some poor results and style of play, but his predecessor thinks he should remain in place.
Van Gaal has come under a lot of pressure for both United's style of play and the poor run of results of late which has seen his side not pick up a win in their last eight matches in all competitions, crash out of the Champions League at the group stage - as well as the League Cup - and slide from the top of the table to sixth and nine points off the pace.
However, Moyes feels it would set a dangerous precedent if the Dutchman were to be relieved of his duties, saying to The Times: “I think what Manchester United stand for is that they keep their managers, they’ve always supported their managers.
"I hope they stick with Louis van Gaal, he deserves more time. It’s still a work in progress, he’s made some signings, and from my experience in Spain it will take time for players from abroad to settle in.”
Moyes himself was sacked towards the end of the 2013-14 season when hopes of Champions League qualification had ended, which set a precedent in itself that playing in Europe's premier competition every season is a minimum requirement for a club of United's stature.
But so far this season van Gaal has endured a worse campaign than the one Moyes presided over - as the Scot reached the quarter-finals of the Champions League and the semi-finals of the League Cup.
However, van Gaal has shown he can guide his side into the top four after last season, and United's hierachy will obviously be hoping for a similar result this time around as they are five points off what should be their minimum requirement for this season.
Without doubt, patience seems to be running thin with van Gaal but one doubts that Manchester United fans are going to take heed of Moyes's advice after his unsuccessful tenure at the club.
There is a degree of sense to what he is saying as it wasn't all easy for Sir Alex Ferguson during his early years at the club, but given the legacy that was left behind, they ought to be performing a lot better than they currently are.
