Kaheem Parris scored one goal in qualifying to help Sabah reach the league phase of the Champions League
Azerbaijani champions Sabah picked up a historic first Champions League win with victory over Slavia Prague.
The competition debutants, who were thrashed by Manchester United in the opening round of fixtures, scored two second-half goals to clinch their win on Tuesday.
Kaheem Parris, who had a first-half strike ruled out by the video assistant referee for offside, swept home a 49th-minute opener - latching on to Ivan Lepinjica's cutback and finishing first time from the edge of the box.
Slavia came close to equalising when Lukas Provod saw a hooked effort saved, before his follow-up header was blocked on the line by Sabah defender Akim Zedadka.
The visitors appealed for a penalty and the VAR had an extended check but decided the ball had glanced off Zedadka's chest before striking his arm.
The hosts sealed their victory late on through a bizarre Joy-Lance Mickels goal.
Slavia keeper Jakub Markovic came well out of his goal and miscontrolled before Mickels had a weak shot from distance.
It should have been cleared by Slavia defender David Moses, but the Nigerian tripped over his feet and the ball bobbled into the net.
The defeat extends Slavia's winless run in the Champions League to 21 matches (seven draws and 14 losses) - the longest in the competition since a 23-game run by Romanian side FCSB in 2013.
Slavia visit Fenerbahce on 21 October in the next round of fixtures, while Sabah host Borussia Dortmund.
