Januzaj insists the advice he is given by veteran stars such as Giggs and Patrice Evra is important.
The Belgian star has become the focus of the media since his impressive display in his Premier League debut against relegation threatened Sunderland.
The 18-year-old scored twice to secure the three points for United and also eased pressure off new manager David Moyes.
Januzaj moved to United from Anderlecht in 2011 and impressed his new manager during pre season, but is yet to pen his name to a new contract - resulting in increasing speculation over is future at the Premier League champions.
The youngster has a wealth of experience around him at United including Giggs, who has appeared 947 times for the club, and Patrice Evra - who has 343 appearances.
And the Belgian insists it is a helpful thing that there are players who have gone through a similar thing at United.
Januzaj is quoted in the Daily Star as saying: "Everyone gives me advice, that's the great thing here at United. I speak a lot with Patrice and Giggsy.
"They have great experience, they're big players at the club and have gone through everything I'm going through.
"Their advice is important. If I play on the left Patrice is behind me so he helps and I'm playing in a similar position to Giggsy.
"I ask him questions all the time as he's been a top, top player for so long. He's a good teacher."
United welcome Southampton, who have the best defensive record in the league, to Old Trafford after the international break.
