Laudrup warned that all the talent in the world will not be enough if the 18-year-old does not keep his feet on the ground.
"I hope he’s the kind of player who knows he will have to develop and move on, not think that just because you’ve played 10 games in the Premier League then you’re already at the top," said Laudrup.
"At 18 or 19 you’re still a boy. It’s very important you’re at the right club with the right people around you – family, friends, the people advising you. Everything like that is important when you’re young.
"Otherwise, sometimes unfortunately, you can see players who play 10 or 15 games at the top level and everyone tells them they’re so great and they believe it and think they’re already in the top three in the world.
"He’s a good player and at a young age is already at this level at Manchester United. There are very good players, great players and world-class players. I don’t know (with Januzaj) because he’s still so young but ask me the same question in three years."
