Despite Van Gaal taking United to third in the table in his first season in charge, some critics have had issues with the style of play employed by the Dutchman.
Another ex-player, Gary Neville, caused a stir when he compared them to a pub side earlier this season, while Scholes also has issues.
Writing in the Independent in the wake of the midweek win over Burnley, he said: "Part of being a Manchester United player under Sir Alex Ferguson, perhaps the most important part of being one of United's attacking players, was that when you were in possession you had to take risks in order to create goalscoring chances
It was not an option; it was an obligation.
"In the periods of my career when I stopped passing the ball forward, or when I stopped looking for the risky pass that might open up a defence, the consequences were the same
The manager stopped picking me
I got back into the team when I went back to doing it the way he wanted.
"United's history was built on attacking football, which does not always mean that the team kept clean sheets or did not concede chances
Why do you think United have had some of the best goalkeepers in the world over the years? They needed them because the team committed so many players forward.
"It does not give me any pleasure to say that at the moment I am struggling to watch Louis van Gaal's team with any great enjoyment
They beat Burnley on Wednesday night but it was Burnley who had by far the best of the first half.
"At times, United's football is miserable
To beat opposing teams you have to attack, and to attack you have to take risks
Too few of the players in the current team are prepared to take those risks."
Scholes scored 155 goals for United during their richest period of success and is at a loss to work out why Van Gaal is employing captain Wayne Rooney in midfield.
He added: "We come at last to the two strikers, Robin van Persie and Radamel Falcao
I feel they look like strangers at times, while Wayne Rooney is moved around the team to accommodate them.
"Wayne can play anywhere on the pitch
He is so willing, and he will give you at least a 7/10 performance most times
Against Burnley he ended up as a defensive midfielder
At other times he has been pushed out to the right-hand side, where he will look for the strikers early or switch the play.
"But if Van Gaal does not think Rooney is a better option up front than the other two then there really is a problem."
