Aberdeen sack boss Jim Goodwin after 6-0 thrashing by Hibs
The Aberdeen hierarchy announced the 41-year-old's axing just 19 minutes after the final whistle had blown in the Scottish Premiership fixture.
The decision also follows The Dons' humiliating 1-0 defeat to minnows Darvel in the Scottish cup on Monday.
The board had publicly demanded an "immediate response" to the club's worst-ever defeat to the sixth-tier part-time side.
Goodwin had been in charge at Aberdeen since February last year but had only won one game in his last ten games in charge.
In a statement on the club's website, Aberdeen Chairman Dave Cormack was brutally honest in his appraisal of Goodwin's recent results.
"I met with Jim at the end of the game. Jim is a thoroughly decent guy. He came up, gave me a hug and said, 'It isn't good enough.'
"He has given it everything he can give it, but the simple facts are that the results since coming back from the World Cup break have been wholly unacceptable and the away form is utterly abysmal.
"I feel for the supporters too. I feel embarrassed, humiliated, shell-shocked at events of the last week. That's how our fans feel and I can only apologise to them."
Aberdeen currently sit in seventh place in the Premiership table., with just nine wins and two draws from their 23 games
