"Recently, the efforts have clearly been below the level we expect," the football club writes on its website.
Thelin joined Aberdeen from Elfsborg in the early summer of 2024. He had a dream start to his new coaching job, but the team then slipped in the league, finishing fifth. The big highlight of the 47-year-old Thelin's time at Aberdeen was the Scottish Cup title, which the club had not won in 35 years.
This season, Aberdeen is eighth in the Scottish league.
