The 21-year-old is considered one of the best strikers in world football despite his young age.
Asked by Sky Sports which players he learns from, Haaland replied: I've been watching a lot of players, let's take for example the run in behind the centre-back when the No 10 has the ball.
"You have maybe the best in the world at that, Jamie Vardy. I've been looking a lot at him on exactly this.
"I have always been watching a lot of football and I still do.
"When we play Saturday, I go home on Sunday and watch football all day."
