The Aberdeen board are due to meet on Wednesday to discuss the future of manager Jim Goodwin following the Scottish Cup loss to sixth-placed Darvel.
Monday’s shock 1-0 defeat at Ayrshire has intensified the pressure on the 41-year-old Irishman.
Aberdeen have won once in nine games and slipped to fifth in the Scottish Premiership.
Monday’s loss followed two more damaging losses in eight days.
A 2-1 extra-time loss to Rangers in the League Cup semi-final was followed by a 5-0 Premiership win over third-placed Heart of Midlothian.
But the loss to part-time Premier League West of Scotland leaders Darvel was widely touted as the biggest upset in Scottish Cup history, given that five levels separate the teams.
What was arguably the worst result in Aberdeen’s history comes at the start of the 40th anniversary year of their greatest triumph – the European Cup Winners’ Cup final victory over Real Madrid.
Although he described Darvel’s defeat as ’embarrassing and humiliating’, Goodwin said ‘I believe I can turn the tide’ after agreeing their form ‘wasn’t good enough’ for a club of his stature. of Aberdeen.
Goodwin was brought in last February on a two-and-a-half-year deal by top-flight rivals St Mirren to replace Stephen Glass, who was made redundant 11 months after taking over from Derek McInnes.
