Aberdeen boss Mark McGhee was left stunned after his disillusioned players savaged his coaching methods, reports the Scottish Sun.
The under pressure Dons boss kept his side in the dressing room for an hour-long inquest after Saturday's loss at Falkirk.
SunSport understands several players attacked McGhee's training regime, the constant changing of playing systems and the relentless demand for them to report for early Sunday morning sessions.
Blunt talking Dons stars also complained about fitness work they don't believe is effective.
That's led to deep unhappiness. McGhee took on board the frank opinions and the players were immediately given Sunday and yesterday off.
Now McGhee hopes troubled Dons can pick up the pieces with a win over Hearts this Saturday.
He is happy to compromise - but is demanding results in return to ease the mounting pressure.
He said: "There are things they would like to do differently, so I'll be thinking about that over the next couple of days."
