The Green Brigade have urged their members to "hold off" renewing their Celtic season tickets as they seek talks with fellow supporters' groups.
The club's Ultras have been vocal critics of the board and have once again shared their concerns after the Parkhead side announced season tickets are going on sale before a new manager is confirmed.
Eddie Howe is expected to usher in a new era at the club after a season to forget as rivals Rangers romped to the title.
Celtic have frozen prices on season tickets and have also included a £50 retail voucher but some supporters were left puzzled the big announcement was not accompanied by a new boss.
And now the Green Brigade – who supported the Celtic Trust's call to allot last year's season ticket holder with shares – want talks with other leading groups.
A short statement on their Twitter page read: "We share the frustration of many around the season ticket launch and plan to consult NCC members ASAP.
"We'll also speak with other fan orgs to discuss a joined-up approach. In the meantime, we'd encourage all in the North Curve to hold off renewing their season ticket."
