Aberdeen chairman Dave Cormack is braced for the “exhausting” process of recruiting a fourth new manager in the space of three years after Barry Robson was sacked on Wednesday.

First-team coach Peter Leven and under-18s coach Scott Anderson have been placed in temporary charge while the Dons board begin the now-familiar task of searching for a new boss.

Alex Neil, Neil Lennon, Robbie Neilson, Neil Warnock and Stephen Robinson are among those to have been linked with the Pittodrie vacancy.

Almost 12 months to the day after stepping up from his role with the under-18s to take charge of the first team – initially on an interim basis – Robson was relieved of his duties along with assistant Steve Agnew.

Tuesday’s 1-1 draw at home to Dundee, in which the 45-year-old came under fire from sections of the Dons support, proved to be the final straw, with a club statement saying this season’s results and performances in the cinch Premiership “have been well below the expectations set”.

Robson was appointed Aberdeen manager on a permanent basis last May after overseeing impressive form during his stint as caretaker, with a run of seven successive wins helping the Dons overhaul Hearts to claim third place and a crack at European group-stage football.

Cormack lamented the fact the Dons were unable to replicate such form this season as he described the current league position of eighth as “unacceptable”, even allowing for the demands of trying to juggle domestic matters with competing in the Conference League.

“Although it has been a difficult call, the board felt the change was necessary and in the best interests of Aberdeen FC,” the Dons chairman told the club’s website.

“Barry earned the right to be Aberdeen manager and knew the high level of expectation we had when he took the role.

“We gave Barry as much time and support as we possibly could in the hope, and expectation, he could return us to the league form we witnessed in the spring of last year.

“There is a talented squad of players at the club which makes our current league position unacceptable.

“With 17 games left in the league and still in the Scottish Cup, this change is necessary to help us refocus on our ambitions for the rest of the season.

“It’s important we thank Barry for his significant contribution to Aberdeen as a player, a coach and manager. He’s a good man who worked extremely hard in everything he did for us, and it goes without saying that we wish him, and Steve, our very best.”

Following the relative stability of having Derek McInnes in charge from 2013 to 2021 – finishing in the top four in each of his seven full seasons in charge – the Dons have seen Steven Glass, Jim Goodwin and Robson all last no more than a year at the helm before being sacked with the team in the bottom six.

Cormack is frustrated that he and his fellow Dons directors find themselves on the hunt for yet another new boss at a time when the club is “in good shape” off the field.

“The club, as a business, is in good shape,” he said. “We have no bank debt, significant commercial growth, record season ticket and AberDNA membership sales.

“We also have an evolving player trading model that is allowing us to invest significantly more in the football operation than the operating income we generate.

“But, as chairman, I accept responsibility, along with the board, for the managerial upheavals. It’s exhausting for everyone to go through, not least our fans and the managers who gave their all and lost their jobs.”

Aberdeen’s next two league games are at home to Celtic and away to Rangers before they host League Two side Bonnyrigg in the last 16 of the Scottish Cup.

Barry Robson has been sacked as manager of Aberdeen, with the team eighth in the Scottish Premiership table.

The 45-year-old has departed along with his assistant Steve Agnew following the 1-1 draw with Dundee at Pittodrie on Tuesday.

He led the club to a third-placed finish last season and qualification for the Europa Conference League but managed only one win in his last five league games in charge.

The club said in a statement that results and performances this season had “been well below the expectations set”.

“Although it has been a difficult call, the board felt the change was necessary and in the best interests of Aberdeen FC,” chairman Dave Cormack told the club website.

“Barry earned the right to be Aberdeen manager and knew the high level of expectation we had when he took the role.

“We gave Barry as much time and support as we possibly could in the hope, and expectation, he could return us to the league form we witnessed in the spring of last year.

“There is a talented squad of players at the club which makes our current league position unacceptable.

“With 17 games left in the league and still in the Scottish Cup, this change is necessary to help us refocus on our ambitions for the rest of the season.”

Cormack said first team coach Peter Leven would take training on an interim basis.

Steve Agnew admitted Aberdeen are expecting to host a different Rangers side on Sunday to the version they defeated 3-1 at Ibrox almost two months ago.

The Dons pulled off an impressive victory over the Gers on the last day of September, leading to the sacking of the Glasgow club’s boss Michael Beale two days later.

Since then Philippe Clement has taken over and overseen a seven-game unbeaten run in all competitions – including six wins – ensuring Rangers head to Pittodrie this weekend with renewed confidence.

“Obviously that was an encouraging performance and result at Ibrox but there have been changes there,” said Dons assistant Agnew on Thursday. “They’ve obviously changed the coach and results have been good since the new coach has come in.

“Rangers will be slightly different because a new coach usually changes the way he wants the team to play. We’re aware of that and we’ve analysed Rangers.

“We know it will be a tough game but we’re all really looking forward to it. We’re quietly confident. There will be a great atmosphere on Sunday and we believe we’re more than capable of getting the result we want.”

Aberdeen and Rangers meet again three weeks later in the Viaplay Cup final, but Agnew is adamant the Hampden showdown on 17 December will not come into the Dons’ thoughts this weekend.

“I think Rangers at Pittodrie, Sunday lunchtime, is as far as we look,” he said. “All our focus is on that. Anything beyond that, we really don’t look at. Sunday is just an exciting fixture that we can’t wait for.”

Sunday’s match is the first of 12 for Aberdeen in just over five weeks before they sign off for a short winter break after their trip to Ross County on 2 January. Agnew is confident the Dons – currently ninth in the league – are equipped to handle the demands of what promises to be a gruelling run.

“It is a big challenge, the number of games coming in such a short period of time,” he said. “We adapt training because of the amount of games and in the summer the club were terrific in terms of the recruitment so we have a squad in place to take us through this hectic period.

“We’re all quietly confident as a group that by the time we come through all this, we’ll be in a healthy place, whether that’s a cup final that goes well or moving up the league.”

Barry Robson has targeted European football after extending his deal as Aberdeen boss.

The former Dons midfielder took over from Jim Goodwin in January and was put in charge until the end of the season.

However, Aberdeen have now announced Robson and his assistant Steve Agnew have agreed two-year contract extensions and will remain at the club until at least the end of the 2024/25 campaign.

After seven straight wins, the Dons are in a strong position to finish third in the cinch Premiership, sitting five points ahead of Hearts with five fixtures remaining.

Robson told the club’s official website: “I am honoured to have been given the opportunity to manage this fantastic football club.

“I would like to thank the chairman and the wider board for putting their trust in me and together with Steve and my staff we will work tirelessly to match the ambitions of the club.

“Since being asked to take the team at the end of January the response from the players has been immense, and likewise the supporters have been brilliant and got right behind the team. They have played their part in our recent wins.

“We still have five tough matches remaining this season but we’re all more determined than ever to deliver European football again for the supporters and longer term meet the expectations of this great club.”

Robson will officially become the 24th managerial appointment in the history of Aberdeen.

Chairman Dave Cormack said: “We are delighted to announce the appointment of Barry as men’s first team manager.

“Barry has not only delivered excellent results on the pitch over the last couple of months, he’s also been instrumental in implementing a holistic approach at Cormack Park, whereby youth academy and first-team coaches and staff are working closely together on a club-wide approach to player development, delivering a consistent playing philosophy from the academy to the first team, and maintaining and developing the player pathway to first team football.

“He immediately recognised the need to surround himself with experience to help him in his growth and we are pleased that Steve Agnew has agreed to become permanent assistant manager.

“Barry’s focus now, whilst clearly pushing to secure European football for the club, will be on the recruitment process for next season.”

Agnew said: “I’m delighted to join Barry as part of the coaching team at this great club.

“I have really enjoyed my time here so far. It is a fantastic club with amazing supporters at its core.

“They have got behind us home and away and the support has contributed to our run of form.

“Our goal now is to finish this season strong and continue to plan for 2023/24.”
