The Norwegian's are both seemingly leaving this summer.
This week saw Celtic confirm that manager Ronny Deila would be stepping down from his role at the club in the summer by mutual consent.
Now it is being reported that one of his favourites at the club could also be on his way out of Celtic.
Deila brought his countryman with him from Stromsgodset in Norway back in January 2014, six months after becoming Celtic boss.
In his time at the club he has caught the eye, winning the PFA Scotland Player of the Season last term. However, he has had a poor season this term and Celtic are set to let him go. The report claims he is wanted by several Bundesliga teams and that he is unsettled at Celtic, especially with the departure of Deila.
His contract has 12 months left to run and negotiations over a new deal have now come to an apparently permanent stalemate.
With that in mind it would appear likely that Celtic will want to sell the player in the summer, rather than lose him for free in a year.
