Aberdeen name Swedish boss Thelin as new manager from summer 2024
The club, ninth in the table, sacked Barry Robson in January after nine months in charge and, following a brief spell with Neil Warnock at the Pittodrie helm, installed Peter Leven as interim boss in March.
"Jimmy Thelin has been appointed as the 25th permanent manager of Aberdeen," the club said in a statement.
"The Swede, together with assistants Christer Persson and Emir Bajrami, will leave their current roles at Allsvenskan side Elfsborg this summer, taking up post at Pittodrie in early June."
Thelin, 46, led Jonkopings Sodra to the Swedish top flight in 2015 in his first job as manager and in 2017 was appointed boss at Elfsborg, whom he has twice guided to the Allsvenskan runners-up' spot.
He said: "I'm very honoured to be the new Aberdeen manager and to be coming to this great club and city. I wanted to be sure I was making the right step in my career, particularly as this will be my first time managing outside of Sweden."
