The Norwegian left the Scottish Premiership side at the end of this past season.
Celtic manager Ronny Deila
The 40-year-old endured a mixed two year spell with the Hoops, as while he was able to lead the side to two Scottish Premiership titles and League Cup success, they made little impression in Europe and an Old Firm defeat in the Scottish Cup semi-final arguably confirmed that he had not overseen the kind of progress that was necessary during his tenure.
But his countryman - who also struggled with life in Glasgow having gone through a torrid spell with Rangers during his playing career - suggested that not being given enough time to focus on the team was one of the main reasons that things did not quite work out.
"I know Ronny well and while he is an ambitious person he is also a modest person," he told The Scottish Sun.
"He has always made himself available to the press and he is always down to earth.
"He is a clever football guy and the more time he can work with the players the better his teams will be.
"It would have been better for the club if Ronny was focusing on the football rather than the media."
Though Deila's time in charge is unlikely to be remembered with a huge amount of fondness by Bhoys supporters, there are certainly some positives from his spell that will aid his successor, Brendan Rodgers.
As well as the trophies that he won during his tenure, he also oversaw Leigh Griffiths' transformation from a decent option to have in the squad to the most ruthless striker in Scotland currently.
It was also his time in charge that saw Kieran Tierney handed a run in the side that allowed the 18-year-old to cement his status as one of the brightest talents in the country.
Though the left-back's talent meant that it was inevitable that he would earn his chance, Deila took the gamble to give him an opportunity and send a message to some of the other promising youngsters that the pathway from the academy is there.
