Aberdeen parted ways with manager Jim Goodwin just minutes after Saturday 6-0 loss far to Hibernian.
Pittodrie’s board have demanded an “immediate response” to the club’s worst defeat to sixth division side Darvel on Monday.
Instead, Goodwin’s side were blown away by an equally faltering Hibs, taking Aberdeen’s recent run to a 10 win.
The announcement came just 19 minutes after full time.
Goodwin, 41, was appointed on February 19.
“Jim is a good man, he gave his all here. I met him right after the game and he came over and gave me a hug and just said, ‘I know, Dave, it’s just not pretty well, “said the president of Aberdeen. Dave Cormack told BBC Scotland.
“So we are parting ways for obvious reasons. Since we came back from the World Cup, our away form has been abysmal, our home form has been pretty decent. I think some players have to take responsibility as well. As a Dons fan I’m 64 now I’ve been going there for almost 60 years I take responsibility I’m the president of the club and I’ve overseen football-wise the changes we’ve made .
“Like the fans, I felt quite humbled today and I’m sorry – they were brilliant today. I’m quite emotional for the club. It means everything to me. It’s our hometown. I’m long gone. I rightly take the skins. I deserve it but I’m determined to do it right.
Earlier this month, Aberdeen also lost a League Cup semi-final to Rangers in extra time and suffered a 5-0 league defeat by Hearts.
The loss to part-time West of Scotland League Premier Division leaders Darvel is widely regarded as the biggest shock in Scottish Cup history, given that five tiers separate the sides.
Aberdeen’s worst result comes as the club enter the 40th anniversary year of their greatest triumph – the European Cup Winners’ Cup final win over Real Madrid.
The Pittodrie club have now sacked their last two managers shortly before completing a year in office.
Goodwin had been brought on a two-and-a-half-year deal from top-flight rivals St Mirren to replace Stephen Glass, who was let go in February, 11 months after taking over from Derek McInnes, who spent eight years in charge.
Goodwin, who began his playing career with Celtic before playing with Stockport County, Scunthorpe United, Huddersfield Town, Oldham Athletic, Hamilton Academical and St Mirren, began his managerial career by leading Alloa Athletic to League promotion 1 Scottish.
He returned to St Mirren, which was two places above Aberdeen when the Pittodrie club decided to appoint him as manager.
