Celtic held a much needed crisis meeting on Thursday morning
The Celtic boss saw his team struggle to a 0-0 draw with Dundee on Wednesday evening, and immediately called his players in for a crisis meeting the following morning.
He was seeking answers as to why the players were performing so badly, with their last two draws allowing Aberdeen to get back into the title race.
Even performances which have brought victories have been very hard to defend, as the football has been extremely poor and Celtic fans are starting to turn on Deila and the players.
They hold a four point lead over the Dons, but with 10 games left it is likely that that gap will close over the coming weeks. Celtic do not look to be getting any better, and Aberdeen will know they can take advantage and take the lead in the title race.
The meeting was expected to lead to a shouting match between Deila and the players, with the team not happy with many of the head coach’s recent decisions.
Team selections have been particularly frustrating to the players, and the report also claims they are disappointed with the recent restructuring of the medical set-up at Parkhead.
Deila is under no immediate pressure to lose his job, but failing to win the Premiership title could lead to Peter Lawwell and Dermot Desmond making a decision on his future.
