The experienced manager thinks his former club should retain their Premier League status for next season and believes that 36 points will be enough to survive the drop
The former Canaries striker, who has been in charge of Oldham, Manchester City, Everton, and Norwich's rivals Ipswich Town in an illustrious managerial career, feels confident that Chris Hughton's side will be in the top flight next year.
"I strongly expect Norwich to be in the Premier League next year," Royle told the Eastern Daily Press, "It won't take 40 points.
"The last survival place at the moment is taken by two points under an average of one point per game.
"Aston Villa are on 24 points from 26. You transfer that to the end of the season and that would make 36 a survival target."
Royle went on to state that the attacking players in Norwich's squad will be vital in ensuring their top-flight status.
"Luciano Becchio will score a few goals; Grant Holt as well," Royle continued. "If Alex Tettey keeps patrolling the midfield, certainly seven points is not beyond them and that would keep them in the division."
Norwich currently sit in 14th place in the table, six points clear of the relegation zone, but face Everton away before welcoming league leaders Manchester United to Carrow Road on March 2.
