Willy Boly scored a 93rd-minute winner for Wolves as they won their first ever Europa League group game, beating Besiktas 1-0 in Istanbul.
Both sides lost their opening Group K games two weeks ago and have won just one league match so far domestically, and it showed in a game that lacked finishing quality.
But ultimately, Wolves put in a classic away performance, keeping Besiktas at bay for much of the game before scoring a late winner as Boly turned the ball home late on.
Wolves move off the bottom of Group K and into third, one point behind Braga and Slovan Bratislava, who drew in Group K's other game on Thursday. Besiktas are now in fourth as their dismal start to the season continues.
