The Red Devils have picked up just one win from their opening five Premier League games and slipped to a shock 5-3 defeat at newly-promoted Leicester City on Sunday.
However, despite the inevitable questions being asked of the new United boss, Van Persie is confident that Van Gaal is the right man to lead the club in the right direction.
“I think his numbers speak for itself,” Van Persie told Fox Sports News.
“He has succeeded everywhere he has managed. Everyone believes in his philosophy as well.
“If you look at the players we have now, the staff we have, the stadium, the fans – if you add all those things up, I’m very confident for the future.”
