A solitary goal from Boris Maric was enough to give visitors NK Zrinjski the upper hand in their UEFA Champions League first qualifying round meeting with F91 Dudelange in Luxembourg.
Franjo Dzidic's Bosnia-Herzegovnian Premier League champions took the lead in the 15th minute of the first-leg encounter to take control of the tie ahead of next Wednesday's return leg in Mostar.
A draw on home territory would be enough for Zrinjski to book a second qualifying round match with Austrian champions SK Rapid Wien.
