The Green Brigade have ramped up their ongoing campaign against Celtic chief-executive Peter Lawwell.
The ultras group have issued a fresh statement demanding major boardroom upheaval as they unfurled a new "Wanted" banner outside Celtic Park.
It accused the 61-year-old of "gross negligence" and declares he must be "fired or resign" as they warned 60,000 season tickets are at stake.
Lawwell has overseen a, so far, disastrous season which was compounded by an ill-fated midseason training camp in Dubai plunging the club into Covid-19 chaos.
Neil Lennon 's team are 21 points adrift of runaway Premiership leaders Rangers and their 10 In A Row dream looks dead in the water.
The Green Brigade led calls for change as the campaign began to unravel late last year and they've now intensified pressure on Lawwell to either walk away or be dismissed.
The group are determined to usher in a "new era" with a long-term aim of establishing fan ownership via The Celtic Trust.
A statement read: "The 2020/21 season began with a record number of season ticket holders committing tends of millions to the club against a backdrop of total uncertainty. Our return has been a calamitous season of historic proportions.
"Promised ‘added value’ for our investment, our latest installment came by the way of a Peter Lawwell parody-like apology for the inexplicable Dubai trip. The insulting claim of being the ‘most affected club’ by the pandemic sails to disguise Jos own neglect and demonstrates a shocking lack of self awareness. The Dubai episode has been representative of our season as a whole - short sighted decisions, predictable outcomes, contempt for fans.
"In recents years fans have raised alarm, warning that the biggest threat to our ambitions would be the incompetence of our custodians. In recent months this concern culminated in desperate protests calling for corrective action at a time where our season was still salvageable. Instead a January review was offered.
"Now 21 points adrift and 13 players light, the anticipated January review must stretch beyond the manager and not overlook the approaching season ticket renewals. Changes are requires fro the boardroom to the dugout however the buck stops at the top. Peter Lawwell should tender his resignation as Celtic’s Chief Executive Officer.
"As a new era dawns at Celtic, fans have an opportunity to enact change in how our club is governed. The relationship between the support and the current custodians Is beyond repair, A structural change is required to put the lifeblood of Celtic first; the fans.
"We believe that the Celtic Trust is the vehicle for that change and while the journey towards fans ownership may be long, meaningful fan engage gene will only improve as we progress that campaign."
