The Bhoys boss says it is time for his side to wake up again or risk blowing the title.
Celtic manager Ronny Deila has sent a dire warning to his side, telling reporters that the situation at the club has become critical as they risk blowing the Scottish Premiership title, according to quotes published by the Scottish Sun.
The Bhoys have dropped four points from their last two matches after being held to a 0-0 draw at home to Dundee on Wednesday night, and their lead over Aberdeen at the top of the table has been cut to just four points.
The Hoops players were jeered off the pitch by their own supporters amidst rising discontent against the Norwegian and his side, and Deila admits that the situation has become serious as they look to win a fifth title in a row.
He said, as quoted by the Scottish Sun: "I’m aware of the situation and that the situation is critical. No one more than me feels that. But I believe I can change it and make it right, and that’s what I’m working towards every day.
"Performances can change this — nothing else. That is the only thing you can talk about. Of course there’s pressure. There is pressure all the time, and when we are performing as badly as we’re doing now then there is more pressure.
"It’s true if Aberdeen win every game and we slip up they will be the champions. But it’s also true if we win our games then we are the champions. We just have to keep winning games and performing."
Deila has insisted that he is not afraid of being sacked by the club despite increasing dissent from supporters, and reportedly called his squad in for a meeting less than 24 hours after the stalemate on Wednesday.
However, his position at the helm at Parkhead would be seen by many as untenable if he failed to steer the Bhoys to their fifth successive league title after having had such a healthy lead.
The Glasgow side take a break from league action this weekend to face Greenock Morton in the quarter-final of the Scottish Cup and they will be hoping that it is a chance to rebuild some confidence and momentum.
