The Norwegian admits it doesn't help the players but can't deny he understands why Celtic supporters are so frustrated.
But the 40-year-old says he can understand the frustration among supporters after a dour campaign where even a Scottish Premiership title isn't enough to lift the sense of gloom.
Deila is quoted as saying by the GET: "It’s not helping, I can assure you of that. You can see it in some of the confidence of the boys.
"But these are the circumstances right now and I can understand the fans. A lot of them have been here for 40 years. I have been here for two.
"But the most important thing is to end the season well, get over the line and make it five in a row for the club."
Players, board and manager will have to do a lot more to keep Celtic supporters happy next season.
Rangers will now be a constant threat - in the same division as the Bhoys again - and Celtic will need to appoint the right man to deal with the threat.
The squad themselves need to respond to their manager and the board need to actually invest in that squad.
But Celtic's next managerial appointment will be key. Would Roy Keane be too aggressive? Would Henrik Larsson be too much of a risk? Will David Moyes be too conservative? There's plenty to consider at Parkhead this summer...
