The Swede enjoyed a historic high during his tenure, leading Aberdeen to Scottish Cup glory with a memorable victory over holders Celtic at the national stadium. However, despite that success, his spell in the Granite City has now come to an end.

Thelin met with the Aberdeen board — Dave Cormack, Allan Burrows and Lutz Pfannenstiel — to formally conclude his departure, as the club begins its search for a sixth manager in the space of just four years.

It is fair to say Thelin was backed financially, with significant investment made in Bilalovic, Milanovic and highly rated youngster Mitchell Frame. However, none were able to consistently live up to expectations.

Peter Leven will take interim charge alongside Craig Hinchliffe for the upcoming double-header next week, where Aberdeen will face Rangers at Ibrox.

Thelin said: “Today my time as manager at Aberdeen comes to an end. It is with great respect for this historic Club that I accept this decision.

“Results ultimately decide the tenure of this profession, and as such I take my share of responsibility.

“I believe wholly in the work that was done; however, football doesn’t always allow time for belief to become results. I would like to thank the players for their commitment and effort during my time as their coach, and the staff who worked every day with loyalty and pride.

“I would also like to thank the supporters. Your passion for your team never waivers, even in disappointment.

“Aberdeen will forever be a part of my journey, and it has been an honour to lead this great Club and share that memorable day together at Hampden.

“I leave wishing success to everyone involved both on and off the pitch.”

Chairman Dave Cormack added: “In wishing Jimmy and Christer the very best for the future I want to thank them for delivering our first Scottish Cup win in 35 years last May.

“These memories will last a lifetime, and Jimmy will be forever etched into Aberdeen’s history for delivering such a special day for our supporters, as only one of six Aberdeen managers to win the Scottish Cup in our storied 122-year history.

“However, after significant investment in recent windows, we have not kicked on in the way we hoped or expected following that success. We have tried to give the situation as much time as possible, but recent performances have been significantly below the standards we expect, and we believe it is now right to take a different direction.”
