Ronny Deila has admitted that his departure from Celtic this summer is likely to please some members of his playing squad.

The 40-year-old announced on Wednesday that he intends to step aside at the end of the season after just two years in charge.

Deila says that his decision to quit the club is down to a lack of improvement during his time at the helm, but the Norwegian also believes that it could spark life into certain fringe players.

"Some will be a little bit sad, some will be happy," he is quoted as saying by Sky Sports News. "It's always a new opportunity for everybody. When you have a big squad somebody is not as happy as others if they don't play.

"Improvement is one of my biggest values. When you don't get it, it kills me inside and I lose energy. I don't think there has been a lot of improvement and, when you don't get improvement, the outside pressure is going to get harder and harder as well. I have no problem dealing with that.

"I have been sitting in this room a lot of times and there has been a lot of difficult questions. That is not the problem. The problem is when you don't get improvements and the things you said you wanted to create when you came in the door, you haven't created. One of the reasons we haven't had that improvement is because of the pressure and speculation around me all the time."

Celtic are still on course to win the Scottish Premiership title, but they exited the League Cup at the semi-final stage and also lost to rivals Rangers in the Scottish Cup last weekend at the same stage.
