Aberdeen fans chanted "sacked in the morning" as embattled manager Jimmy Thelin's miserable start to the season continued with a meek Scottish Premiership defeat against Dundee United at Tannadice.
Goals from Ivan Dolcek and Bert Esselink either side of half-time inflicted a fourth league loss from their opening five matches for the Scottish Cup winners.
Dolcek - with his fifth goal involvement in his first five games for United - found the bottom corner just before the interval with a fine strike on his weaker right foot.
Then a helping hand from Aberdeen allowed Jim Goodwin's side to double their lead on 50 minutes. Esselink was left all alone from a corner and powered a header beyond Dimitar Mitov after a flick-on from Vicko Sevelj.
Thelin's side still haven't scored in the league and although they created several good chances, they again lacked a clinical touch.
Jesper Karlsson headed a decent chance wide in the opening stages and lashed a golden opportunity over the top in the second half, while Stuart Armstrong's curling effort from range bounced out off the bar.
Thelin - who has won just four league games in 2025 - was mocked by the home fans throughout the contest, with the sizeable away support joining the calls for him to go late on, and booing on the full-time whistle.
