The former Manchester United midfielder doesn't think the side are too far away from returning to winning ways.
United have only taken one point from their opening two Premier League games, and were humiliated by League One opposition in the form of Milton Keynes Dons in the Captial One Cup, losing 4-0 on Tuesday night.
Sharpe has said that time is needed to get things right at Old Trafford following a disappointing campaign last season under David Moyes where the side finished seventh, without a trophy, and without any European football this season.
He told TalkSport: “He has only been there five or six weeks so it’s too early to judge him. A little bit of patience is needed. It is a long-term approach for Van Gaal and I think you have got to trust him.
“He is the right man for the job. He is a strong character, he is not intimidated by big-name players, big signings, the size of the club and the task of the job at hand. I don’t think he is intimated at all, I think he quite enjoys it.
“It is just going to take a bit of time to get the team he wants and get them to play the way he wants them to play and to produce the standards he sets.
"I don't think they are a million miles away. They have just not started as everybody thought they would do."
There have been concerns that United have looked poor in games and are not showing much signs of encouragement, or returning to a style of free flowing attacking football.
Of course time should be given to a manager to get to grips with the job at hand, and as Van Gaal said, he can't build a team within a month, especially one that wasn't playing with much confidence towards the end of last season.
But there are going to be those who want to see some green shoots soon, if not results. Results bring confidence but if there are games that United are playing well in, it would give some sign that things are starting to work.
