Ljungberg wore a grey jumper and blue open-neck shirt with the club jacket on top.
And Scholes, a former rival of Ljungberg's at Manchester United, claims that his choice not to wear a suit at Carrow Road shows he won't be the "right man" for the job.
Scholes told Premier League Productions: "You would think he'd be out in a suit to show a bit of proudness that he took the job.
"To me that's a great start - shirt and tie to show some discipline.
"I don't think he'll be the right man."
