Andy Walker insists Celtic are guilty of an "embarrassing and insulting" failure to communicate with fans.
The former Parkhead star is furious that supporters haven't been updated on the club's promise of a January review into Neil Lennon 's future.
The club are now staring at the painful scenario of Rangers being able to win the league at Celtic Park in March.
Walker reckons most fans know 10 In A Row is all-but gone and insists they deserve to be presented with a recovery plan.
He's accused the board of showing punters a lack of respect and demanded they be told what the verdict is on Lennon and offered clarity on incoming CEO Dominic McKay's remit.
Walker told Sky Sports : "As things stand right now, I haven't spoken to a single Celtic supporter who believes in the current set-up and the lack of communication from a senior figure at the club to address the fans' concerns is embarrassing and insulting.
"Season-ticket holders are being asked to buy into a set-up that is unclear. They deserve more respect than they're currently getting from this Celtic board.
"If the board wish Neil Lennon to stay in place for the rest of this season and beyond, tell the fans. If they want to make a change at the end of the season, tell the fans.
"If a different structure altogether is to be put in place, tell the fans.
"It won't be too long till the biggest games of every season for Celtic - the July Champions League qualifiers - come around.
"New chief executive Dominic McKay starts his post with the club on July 1. Is it his role to identify new players and/or the possibility of a new coach/manager? Unbelievably, no one knows.
"Now that it's only a matter of time before Rangers deservedly clinch the title, the Celtic fans should be given hope for next season.
"Tell them what the plan is."
