Celtic chief executive Peter Lawwell has called for unity as he told unhappy fans that "strength in adversity" is needed to overcome a poor run of form.
Supporters gathered outside the stadium on Sunday night to call for the removal of manager Neil Lennon following a 2-0 Betfred Cup loss to Ross County.
As exclusively revealed by Record Sport the scenes had the opposite effect, making biggest shareholder Dermot Desmond determined not to bow to the mob.
Lennon will remain in charge for at least Thursday's Europa League clash with Milan, and Lawwell has called for unity between the club and fans as he insisted their concerns are NOT being ignored.
In a statement the Parkhead chief said: "Like all those with Celtic’s best interests at heart, everyone at the club is feeling the same hurt, disappointment and frustration following the team’s recent results.
"We are accustomed to winning and, of course, our objective will always be for that to continue.
"There is no complacency whatsoever.
"Neil, the players and backroom staff, who have already done so much for the club, share in all of that. They have never been more determined to succeed. Having enjoyed such sustained, unprecedented success, we now need strength in adversity.
"We know that many Celtic supporters share very honest and real concerns and they are being heard by the club. Every decision taken, both on and off the park, is with the club’s best interests at heart. This is not about any individual, but about Celtic Football Club as a collective.
"Together we have faced unique difficulties in the early part of the season. While some of these were beyond our control, of course we recognise we must improve. There is a long way to go and everyone at the club is ready for the challenge.
"Later this month, Celtic will attempt what no other club in the world has achieved – a quadruple treble in domestic competitions.
"We can best prepare for that and for our other remaining competitions this season by moving forward together, with the sole aim of achieving continued success for the club."
