The midfielder has struggled for form for the Scottish Premiership side this season.
Celtic boss Ronny Deila has insisted that he is not favouring Stefan Johansen after it was suggested that their previous history together was the reason behind him keeping his place in the side, The Scottish Sun reports.
The midfielder has struggled for form for the Hoops this season, and thus, there have been some suggestions from certain sections of the club's supporters that Deila continues to select him as he previously played under him at Norwegian side Stromsgodset. However, Deila has defended his decision to continue picking Johansen, and denied that any favouritism was involved.
"Stefan was at Celtic before I was and he was voted the best player in the country last season," he told The Scottish Sun.
"I don't want to say too much - it's up to others to decide whether it's fair or not.
"All I will say is that we win as a team and we lose as a team and whatever happens it is important we're united."
As Deila suggested, the Norway international enjoyed a fantastic first full season at Parkhead. His 13 goals helped the Bhoys win both the Premiership and the League Cup.
However, this campaign has been much more of a struggle for Johansen. He has scored just once and bagged two assists in the league.
While the midfielder has come in for criticism, he is arguably not the only player that has failed to replicate his form from last season this time around.
And with Deila under increasing pressure from the fans to secure the title in emphatic fashion - after their failure in Europe and the League Cup - it is perhaps no surprise therefore that he continues to select a player with whom he has the most experience working with.
