However, Van Gaal was unhappy that his players couldn't add further to their tally.
"I said before the match that it would be difficult for us to open up the game," he told Dutch television channel SBS6.
"These teams like Andorra always play very defensively, so that makes it a hard task. My prediction came true, because we won 3-0 and that's not enough."
Friday's win has seen the Dutch top Group D on goal difference with three wins from their opening three games.
