Willie Miller insists Dave Cormack 's stewardship of Aberdeen hasn't been good enough.
The Pittodrie legend has let rip at the chairman's record and boss Jim Goodwin over the handling of Andrew Considine's messy departure.
Aberdeen are now on their third manager in 14 months after Stephen Glass' largely disastrous succession to Derek McInnes was ended early.
But Goodwin has so far failed to inspire an upturn and Miller reckons the pressure is now on the club hierarchy to deliver success.
Miller said on BBC Sportsound: "You have a chairman who's come in and the performances and how the club have dealt with things over the three or four years he's been in charge leaves a lot to be desired.
"Dave Cormack has a lot to prove. It hasn't been good enough.
"Derek McInnes was dispatched and at the time I thought it was the wrong decision at the time.
"Stephen Glass lasts nine or 10 months and gets the axe. The chairman and board have a huge role to play next season. They have to turn it round."
A tearful Considine made his final Aberdeen appearance on Sunday after a disagreement over his proposed contract extension.
In April, Record Sport exclusively revealed the club withdrew an offer to the 35-year-old, who will now move on after 18 years with the Dons.
A public statement from Goodwin stated Aberdeen had made the Scotland defender offer, a revelation Miller is adamant was needless.
Discussion had turned to whether clubs pay too much attention to opinions on social media, to which Miller responded: "There’s a bit of vanity there. You have to be bigger than what’s in the media and online.
"It’s like Jim Goodwin saying Andrew Considine was being offered a six-figure fee. You don’t say that. You don’t have to say that."
Miller continued an impassioned defence of Considine by insisting the contract should not have been taken off the table as a mark of respect to a player who had offered almost two decades of service.
He said: "You've got to take a leak like that, wherever it came from, on the chin and deal with the player and the service that player has given to the club.
"You offer him a contract 25 per cent less than what he was on, he's looking round at the other players who are on much, much higher wages than Andrew Considine.
"He goes back in, wants to open up the negotiations through his agent. That didn't happen, the leak came and the contract was withdrawn.
"Why the contract was withdrawn? I don't know.
"Leave the contract on the table, allow Andrew to decide whether he wants another season or not.
"And then the manager comes out and mentions six-figure sums and the fans start thinking he's on a fortune - but there's players here at Pittodrie on much, more than Andrew Considine but we don't hear what they're on.
"That was poorly handed, as well.
"Listen, every manager's got to come in and make their own decisions, he needs a bit of guidance from the people at the club and how the club works - what is the DNA of Aberdeen Football Club? How do they deal with their employees? How do they deal with a player that has given almost two decades of service, who got injured on the field of play representing the club?
"You have got to deal with that and deal with the player appropriately. I don't think he has been dealt with appropriately.
"The manager's got to make the decision but it's how you deal with that decision. I'm sad and sorry it's finalised the way it has.
"Andrew's got his round of applause today and I think he'll serve another club for another two or three years, wherever that may be.
"I think he goes with all the best wishes of every Aberdeen supporter and anybody who has the best interests of Aberdeen Football Club at heart."
