Aberdeen's wretched winless run extended to eight games despite signs of encouragement, as ruthless Shakhtar Donetsk carved out a Conference League win at a raucous Pittodrie.
The hosts put up a spirited second-half showing once they went 3-1 down after leading, but Jimmy Thelin's side were unable to force an effective route back into the game as the Ukrainian side showed a clinical edge in front of goal.
Jesper Karlsson's early penalty was cancelled out by the first of three well-taken Shakhtar goals, with Yehor Nazaryna firing back across Dimitar Mitov to equalise before the interval.
The majority of Aberdeen fans have stood by the embattled Thelin on their torrid run, but many feared a side with the quality and reputation of Shakhtar would compound their misery.
Two quickfire goals from the visitors made that a reality.
Lucas Ferreira ghosted in at the back post to nod his side into a deserved lead, with full-back Pedrinho firing in a low, powerful drive for his side's third.
The hosts were buoyed by Nicky Devlin's close-range header - capitalising on a rebound from Marko Lazetic's sensational effort - as the Pittodrie crowd rallied around their side.
Thelin's team can take plenty of encouragement from their performance in the second half, as they showed the spirit, intensity, and energy that they have been sorely lacking throughout the start of their disappointing campaign so far.
