Christos Tzolis scored the only goal as Club Brugge edged out Sturm Graz 1-0 for their first win in this season's Champions League.
The Greece international delivered the decisive blow in the 23rd minute at 28 Black Arena on Wednesday.
Both sides were seeking their first point in the competition, having recorded defeats on matchday one against Borussia Dortmund and Brest respectively.
Brugge broke through midway through the first half, as Tzolis controlled before firing in off the post from the edge of the penalty area.
The visitors went close to doubling their lead after the break, but Sturm Graz goalkeeper Kjell Scherpen came to the hosts' rescue with a series of fine saves.
Urged on by the home fans, Christian Ilzer's side went in search of an equaliser, but it did not arrive as Brugge held out for the points.
Data Debrief: Third time unlucky for Sturm Graz
Sturm Graz have now suffered four successive Champions League defeats for the third time in their history.
Meanwhile, the Austrian side have now lost their last four European matches against Belgian opposition without scoring.
By contrast, Brugge maintained their perfect record of three straight wins against Austrian opponents, while they have now kept four clean sheets in five Champions League away games - as many as in their previous 22.
Tzolis' strike came from one of three shots on target, becoming the first Brugge player to register that amount in a single Champions League game since Hans Vanaken did so against Paris Saint-Germain in September 2021.
